Heating system Chevrolet-Niva: change of the heat exchanger for the interior heater. Expert recommendations for replacing a stove radiator on a Chevrolet Lanos, Cruz and Lacetti Chevrolet lacetti replacing a heating radiator with a copper one

With the onset winter period, motorists start using the heater. But in life it happens that the stove stops supplying warm air to the cabin. There may be various reasons for this, so it is worth knowing the methods of diagnosis and repair.

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

Video materials will tell about the repair of the Chevrolet Lacetti heater, replacement of the stove radiator, as well as diagnostics and repair of the unit.

Causes of malfunction of the interior heater

The Lacetti heating system has a standard circuit, like all Chevrolets of this class. In the diagnosis of the stove, there are mechanical and electrical faults. So, the radiator can be covered, which suddenly flows, or the pipe can become clogged. On the other hand, the problem may lie in an electrical malfunction. Consider the main nodes where we will look for the problem:

Heater control unit.
Motor.

The main points and places of malfunction have been identified, you can proceed to diagnostics and repair.

Heater radiator

The first sign of a heater radiator malfunction is a leak from the elements themselves. If the element leaks, then it definitely needs to be replaced, otherwise there will be no warm air in the cabin. It is worth warning that the replacement of the stove radiator, according to the factory technology, is carried out after removing the torpedo. But motorists have come up with a way in which they do not need to dismantle the tidy.

So, let's look at how to dismantle the stove radiator with minimal means:

To begin with, it is worth pushing the seats to the rear position.
Remove the cover from the gear knob.

We unscrew the rods from the wings, and remove the gear lever

Now it is necessary to dismantle the gearbox control drive mechanism. To do this, you have to unscrew the 4 mounting bolts.

Dismantle the console by unscrewing the mounting screws.
With the above operations performed, access to the heater will open. The air duct and air distributor can now be removed.
We unscrew the screws securing the upper casing of the stove. Access to the radiator is opened.
We unscrew all the screws securing the casing, we get full access to the radiator.
Disconnect the coolant supply pipes and remove the heater radiator.

If the procedure seemed complicated enough, then you will have to dismantle the instrument panel and remove the radiator according to the factory scheme.

Now it's worth figuring out which radiator is suitable for the car. The original part has a catalog number - 96554446, as well as dimensions 178 * 168 * 26 mm. The average cost is 5,000 rubles. In addition, there are a number of analogs that are not inferior in quality to the original.

Manufacturer	Catalog number	Price
Kager	32-0456	2000
Termal	116509GS	2000
Polcar	2505N8-1	2700
QML	CR-0705	2500

Luzar	LRh CHLt04346	3500
Stellox	10-35105-SX	3000
Kap	G05RADSD00275	4000

Cold air blows, does not warm. This reason is also hidden in the radiator of the stove. This may be due to the fact that there is a blockage in the pipes or the radiator itself. To eliminate the malfunction, you can try to clean it, but this may not help, and you still have to change the radiator itself or the pipe. For cleaning, you can use flushing agents for the cooling system, which are sold in the automotive market or in car dealerships.

Heater control unit

Another place that can cause a malfunction is the heater control unit. It is a mechanical-electrical component that serves as a control to regulate the interior temperature. It has two rods that regulate the opening and closing of the tap. In this case, the malfunction may lie in the heater cable.
The second variant of the malfunction is a malfunction of the electrical part of the unit. In this case, as practice shows, it is recommended to change the block completely, or give it to specialists for soldering. Of course, repairs can fix the problem, but not for long.

Fuses, relays and electrics

If the motor stops showing signs of life, or does not start at all, then most likely the malfunction is caused by a blown fuse. On the Chevrolet Lacetti, these elements are located both under the hood and in the cabin. Of course, you can find pinouts on the fuse box covers, but not always.

Responsible for heating and ventilation of the passenger compartment in the engine compartment are:

In the cabin, from the side of the driver's door, on the side of the torpedo, there is also a number of fuses that are responsible for ventilation. They are worth checking out too:

f7	20	Air conditioner, stove
f22	15	Stove, air conditioner

To check the fuse, it must be removed from the control unit, see if the thread is intact inside. If there is a break, the fuse should be replaced. Do not forget to take into account the rated power.

Breaks in the electrical circuit or damage to the wiring should be considered when troubleshooting. We are looking for a faulty circuit and repair the damage. To do this, it is necessary to have an electrical circuit and its decoding.

Heater motor

Often, the heater motor can be damaged directly. This may be due to damage to the winding or combustion of the motor itself. In this case, the element may beep, or not start at all. To fix the malfunction, you will have to change the motor.

Consider the sequence of actions aimed at replacing the heater motor:

The first step is to turn off the battery. This is due to safety measures so as not to accidentally short-circuit anything.
Now you need to unscrew the fasteners, and then remove the glove box.

Having gained access to the stove motor, we disconnect the wiring pads - the resistor connector and the power supply of the electric fan.
We unscrew the fastening screws and remove the protective cover.
We unscrew the fasteners of the electric fan, pull it down and towards ourselves.

The stove motor has been replaced. Dismantling for cleaning is carried out in the same way.

The original catalog number of the stove fan is 96554418. The average cost is 6,000 rubles. Only Luzar is presented from analogues, which has the article LFH0564 and the price of 3000 rubles.

Output

You can find the malfunction of the Chevrolet Lacetti stove yourself. This could be due to a radiator, fan, or electrician. You can also eliminate the causes with your own hands, but it is worth studying the heating and ventilation scheme, and you will also need some knowledge and skills in auto repair.

The stove radiator performs an important function in the heating system of every car. In the event of a malfunction of the heat exchanger, the performance of the system is impaired, which not only reduces the comfort of driving, but can also lead to overheating of the motor. Exists characteristic signs that indicate that there is a problem with the radiator and the part needs to be replaced.

Where is the radiator of the stove on the "Chevrolet Niva"

The heating system of a car consists of a number of elements, without which its normal functioning is impossible. One of these is the stove radiator. Sometimes there are problems with the heat exchanger, to eliminate which it is necessary to dismantle the unit. The radiator is located in the passenger compartment behind the heater control unit. In addition to heating and ventilation devices, the car can be equipped with an air conditioning system. If in the first case it is possible to dismantle the radiator without any particular difficulties, then in the second it will take a lot of effort.

Body interior heating system: 1 - ventilation duct; 2 - air duct for heating the windshield; 3 - intermediate body; 4 - intermediate air duct; 5 - air intake filter housing; 6 - heating system fan; 7 - central ventilation nozzle of the passenger compartment; 8 - facing of the control levers panel; 9 - front air duct for heating the passenger compartment; 10 - rear air duct for heating the passenger compartment; 11 - leg heating air duct; 12 - heater assembly; 13 - side nozzle (stove radiator is inside the box 12)

When a radiator needs replacement

With long-term use vehicle, the following problems arise with the heat exchanger:

the appearance of a leak, as evidenced by puddles under the rug on the driver's side, the formation of a greasy film on the glass;
clogging, which affects the bad bandwidth and deterioration of heat transfer.

How to replace the radiator of the stove on a "Chevrolet Niva" without an air conditioner

Before proceeding with the dismantling of the radiator, you will need to drain the antifreeze from the cooling system. To do this, unscrew the bolt on the cylinder block and remove the expansion tank cover. Another option is also possible, in which the tank lid is opened and the cooling tube of the throttle assembly is disconnected. Instead of this tube, another hose is inserted through which the liquid is removed. To speed up the process, you can gently blow out the tank to drain the remaining antifreeze. In addition, it is recommended to disconnect the negative terminal from the battery.

To replace the radiator of the stove, it is necessary to unscrew the bolt on the cylinder block and the plug of the expansion tank to drain the coolant

Tools for the job

To dismantle the radiator you will need:

screwdrivers (flat, cross);
pliers;
nippers;
socket heads of different dimensions (8, 10, 14).

How to remove a stove radiator

It should be borne in mind that the manufacturer's recommendations for car repair are not always the simplest and most affordable for an ordinary motorist. Therefore, quite often you have to rely on the experience of owners who carry out repairs with their own hands using improvised means and tools, resorting to various tricks. Let's start the disassembly procedure:

We dismantle the glove compartment, for which we unscrew the corresponding fasteners. We unscrew the self-tapping screws for fastening the cladding on the right and left sides at the feet of the passenger, remove the terminals of the lighting bulbs.
To remove the glove compartment, you will need to unscrew the corresponding screws and remove the side decorative cladding at the feet
We loosen the clamps of the rubber pipes from the radiator and carefully pull them together, draining the remnants of the antifreeze into the prepared container.
After removing the hoses from the radiator, drain the remnants of antifreeze into the prepared container
After removing the hoses, we unscrew the fasteners of the heat exchanger itself and push the part towards ourselves until it rests against the air duct.
Unscrew the nut securing the relay cover with the head on "8" and remove the element. It will be seen that the corner of the frame interferes with the subsequent dismantling of the radiator. To solve this problem, we remove the interfering part of the plastic with pliers and remove the heat exchanger itself.
To dismantle the radiator from the seat, you will need to cut off a piece of plastic
On a new radiator, it is recommended to glue the extreme edges with foam rubber to avoid air penetration due to a leaky connection.
We also cut off a piece of plastic on the frame of the new heat exchanger, and then insert the part into its seat.
On the new radiator of the stove, it is necessary to cut off the corner of the frame, which will allow the installation of the part in place
We assemble in the reverse order.

How to remove the evaporator and fan

Before dismantling the radiator, you will need to provide access to it. To do this, it is necessary to remove the air conditioner evaporator. We carry out the procedure step by step:

We remove the glove compartment, for which we unscrew all the fasteners.
We dismantle the airbag (if it is present in the vehicle configuration). We remove the negative terminal from the battery, then we look for the red connector of the airbag and take it out. Use a suitable tool to unscrew the cushion mounting bolts. Using a flat screwdriver, pry off the cover on the panel, press the latches from below and pull the pillow up.
Using a key or a head of a suitable dimension, unscrew the two bolts securing the airbag
We remove the air duct from the passenger side. Use a flat screwdriver to pry off the ventilation grill caps, unscrew the screws and take out the grill. Remove the tape and remove the duct.

We bend back the metal brackets.
To ensure that nothing interferes with the removal of the evaporator, you need to bend the metal brackets
Carefully remove the cable, which is responsible for adjusting the damper, so as not to lose the latch. We remove the structure itself to the right.
To disassemble the fan into two parts, remove the latches (6 pieces) by prying them off with a screwdriver. After that, the housing can be separated and taken out downward.
To separate the parts of the fan, it is necessary to remove the latches, after which the elements are removed
The next step is to dismantle the air conditioner evaporator. To do this, under the hood, unscrew the tubes of the air conditioning device. Since freon will begin to leave the system, it is better to avoid getting it into the respiratory system.
We unscrew the nuts from the adjacent studs.
In the engine compartment, you will need to unscrew the nuts from the studs and remove the evaporator tubes
Carefully unscrew the bolts securing the evaporator body so as not to rip off the nuts, and one self-tapping screw located near the radiator pipes.
In the cabin, carefully unscrew the evaporator mounting bolts, as well as the self-tapping screw
We remove the evaporator nozzle to the right until it is free, and you will have to apply some effort. The left front bracket will interfere with the removal of the assembly - it must be pulled and removed from under the panel mount. In addition, the clamps of the radiator pipes will prevent the removal. It is better to loosen them and pull them down. After that, we take out the evaporator itself.
To remove the evaporator, you need to make some effort to pull the bracket on the left side from under the panel mount

How to remove a radiator

Dismantling the evaporator refers to preparatory activities before removing the stove radiator. First, we perform the following step-by-step actions:

This completes the dismantling process. The assembly is carried out in the reverse order. It is recommended to use new fittings during installation, as rubber elements lose their elasticity over time. Optionally, the hoses can be sealed with a sealant. Upon completion of all procedures, coolant is poured into the system to the required level in the expansion tank.

Before the cold weather sets in, it is recommended to check the operation of the heating system and make sure that the radiator connections are tight in order to reduce the likelihood of unforeseen situations. If you need to replace the radiator on a Chevrolet Niva with or without air conditioning, you can do the procedure yourself, despite the complexity of the work. You just need to be patient and follow the step-by-step instructions.

As you know, the efficiency of the stove largely contributes to more comfortable driving. Especially when it comes to the cold season. One of the main components of any heating system in the car is a radiator device, so every motorist must monitor its performance. How to replace the radiator of the Chevrolet Lanos stove and how to determine the malfunction of the device - find out in this article.

Criteria for choosing a heater radiator

First, let's talk about what to look for when buying a radiator device for Lanos, Cruz and Lacetti cars:

As practice shows, the design of this product usually not very reliable, especially when it comes to radiator devices in Lanos. Often, the device mounting brackets break, as a result of which the product passes cold air and, accordingly, does not heat the interior well. In this case, the level of the nominal temperature will decrease, so even when the regulator is set to the most powerful heating, cool air will enter the cabin.

In addition to the breakage of the brackets, the product must be changed in the following cases:

if the device is clogged (you can try to rinse it, but this usually does not help);
if the product is damaged, which contributes to the leakage of coolant;
if the thermostat malfunctions.

Before starting the replacement, it is necessary to exclude all factors that may affect the performance of the heating system. For example, you need to check the pipes and hoses for leaks. If you notice that the volume of antifreeze in the expansion tank has decreased, stains of drips have appeared under the bottom of the car, then it is necessary to diagnose the pipeline. Failed pipes, on which there are traces of damage, need to be replaced (video author - Ruslan Iskhakov).

Removal and replacement instructions

Consider the process of replacing a device using the example of a Chevrolet Lacetti car:

To begin with, the center console is dismantled, there is nothing complicated about it - you just need to unscrew all the bolts that secure it, and then remove the console from the mounts.
Then, all attachments are removed from the console, in particular, the glove box, plastic inserts, you also need to disconnect the cables from the heater flaps and dismantle the central trim. Also remove the glove box and backlight control module, optics adjuster, clock. When disconnecting elements, it is advisable to sign all connectors with wiring, this will allow you to avoid mistakes during assembly during assembly.
Then you will need a long wrench, a ratchet wrench with 10 and 12 heads, and a Phillips screwdriver. Also note that you will need a new thread lock to assemble the center console, purchase one in advance.
Some center consoles are fixed to the beam from the inside, this can cause inconvenience when dismantling the torpedo. There is a self-tapping screw, you will have to unscrew it anyway. All the fastening elements of the center console to the beam are unscrewed. To dismantle the console, you need to lift it slightly and then remove it. You will also need to disconnect all the chip retainers that hold the wires to the beam.
Further, on the right and left sides, you will need to unscrew three screws each, with which the beam is fixed to the car body. Also, in the area of fixing the steering column to the body, you can see six more bolts, they also need to be unscrewed.
Then the beam is dismantled. Having done this, you can proceed to removing the control module for the heater.
There is nothing difficult in removing the module. You will need to unscrew two screws in the passenger compartment, with the help of which it fixes the heater module with the block in which the condenser evaporating device with a filter element is installed.
Then, in the engine compartment, it is necessary to disconnect the two hoses that are connected to the radiator assembly. You should also unscrew the four screws fixing the heater module to the car body.
Further, the module itself is dismantled, after which you can easily remove the radiator device as well. To disassemble the module, you need to unscrew ten more screws. A new radiator is being installed.

The price of the issue

The cost of radiators today varies in the region of 2-3 thousand rubles on average.

The cooling system of the Chevrolet-Niva includes not only such structural elements as a thermostat and a pump, but also a heat exchanger for the interior heater. The unit is located in a plastic casing and is installed in the center of the dashboard, so it is quite easy to detect malfunctions - they are identified visually, and also introduce a certain "aroma" of antifreeze into the interior.

Signs of the need to replace the heater radiator on a Chevrolet Niva car

After a long operating period, it may turn out that the car remains without heating in winter. To exclude the development of such a plot, you need to know the main signs that require increased attention, first of all, to the state of the heater heat exchanger:

the presence of coolant under the mat on the driver's side;
the appearance of a specific smell in the car interior;
after the operation of the heater, a greasy coating appears on the glass;
insufficient degree of air heating;
the need for regular replenishment of the level of antifreeze in the cooling system.

In the absence of antifreeze leaks at the joints, any of the above symptoms indicates that it is necessary to replace the radiator of the Chevrolet Niva stove, and the faster the better. When choosing a new heat exchanger, one should take into account the availability of two types of products on sale: made of aluminum and copper, each one determines the priorities independently - enough has been written about the properties of these materials.

Preparatory cycle

To complete the work, you will need the following set of tools:

head on "10" with a long crank;
head to "8";
head on "14" with a long crank;
set of open-end wrenches;
a set of Phillips and flathead screwdrivers;
pliers.

An obligatory stage of the preparatory work is to drain the coolant. When performing the process of replacing the stove radiator on a Chevrolet Niva car, the drain is carried out in two ways:

in the traditional way - remove the cover from the expansion tank and unscrew the drain bolt located in the front of the cylinder block jacket;
an alternative way is to open the cover of the expansion tank, unscrew the cooling hose of the throttle assembly and close it with a finger, insert another hose instead of it and drain the liquid through it; in this case, you can blow into the tank to completely remove the remains of antifreeze.

Important! To avoid airbags deployment during work, the ignition key must be set to the "Lock" position and the wire going to ground must be disconnected from the battery. You can start work only after 2 minutes, when the backup capacitor is completely discharged.

It is advisable to prepare thin strips of foam rubber, which will be needed for pasting the radiator around the entire perimeter. This procedure aims to minimize gaps and concentrate air flow through the heat exchanger.

The presence of an air conditioner significantly affects the repair process, since it significantly complicates the technological process. In this case, in practice, two options are applicable:

without dismantling the instrument panel - depressurization of the air conditioning system and dismantling of the evaporator followed by charging with refrigerant;
with complete dismantling of the dashboard and steering column - the air conditioning system remains in working order.

Both options at home are difficult to implement, because they contain complex technological steps, so we will consider replacing a faulty stove radiator in a car that is not equipped with air conditioning.

The technology of changing the heat exchanger on a Chevrolet-Niva car without air conditioning

Although the manufacturer himself recommends starting to change the heat exchanger only after complete dismantling dashboard, the motorist ingenuity has proven its worth and made it possible to bypass a number of complex operations. To do this, it is enough to repeat the following technological transitions:

dismantle the glove box by unscrewing all the screws, for this you need a Phillips screwdriver with a short handle;
dismantle the lower air duct directed to the passenger's legs (fixed with one screw);
loosen the clamp of the lower branch pipe and, having prepared a small container (for example, cut plastic bottle), pull off the hose and drain the remaining liquid;
loosen the clamp of the upper branch pipe and pull it off;
unscrew the two self-tapping screws that secure the heat exchanger and push it towards you until it stops in the upper air duct;
unscrew the nut on "8", which secures the relay cover and dismantle it;
saw off with a hacksaw blade or bite off the corner of the plastic radiator housing with pliers and pull it out towards you;
glue a thin layer of foam rubber around the perimeter of the new heat exchanger, the Moment glue is suitable for this, and let it dry;
replace the stove radiator with the regular place of the Chevrolet Niva car in the reverse order, after removing the corner of the plastic case in the same way as on the faulty unit.

After installing the pipes, do not forget to tighten the clamps and screw the bolt to drain the antifreeze on the cylinder block. Now you need to top up required amount coolant into the expansion tank and after a few days of machine operation check the coolant level.

With prolonged use of the car, you can notice the effect of fogging of the glass. In particularly critical cases, an unpleasant odor appears in the cabin from the vents. You can also notice coolant leaks, which is the whole reason.

The radiator of the Chevrolet Niva stove is located in the center console in the place marked with an arrow. This is one of the main components of the cooling system, with which, nevertheless, problems can arise from time to time, like with a thermostat and a pump. If the tightness of the case is broken, the coolant begins to flow into the passenger compartment, which in most cases is noticeable even without disassembling the instrument panel.

To get to the radiator, it is better to remove the panels from the passenger side, since the device is located closer to the right side of the car.

This problem is most common in high-mileage vehicles. There can be many reasons for the appearance, for example, from poor-quality coolant, a factory defect in the production of a part, blockage or increased pressure of antifreeze in the system.

At the same time, there are several signs characteristic of this particular problem that it is necessary to replace the radiator of the Chevrolet Niva stove:

Traces of antifreeze under the driver's or passenger's mat
poor heating of the passenger compartment
traces of grease on the windshield above the deflectors
lowering the liquid level in the expansion tank
the appearance of a specific chemical odor in the cabin

There are 2 main ways to replace a radiator. It's connected with technical characteristics auto. Chevrolet Niva without air conditioning has.In order to independently change the heater radiator, the Chevrolet Niva must be stocked with the following set of tools:

screwdriwer set
pliers
socket wrench for 8, 10 and 14

Before replacing, the terminal is removed from the battery so that if antifreeze accidentally hits the wiring during operation, it does not cause a short circuit. It is important to remember that voltage is maintained in the system for 2-3 minutes due to the operation of the backup capacitor.

After that, the antifreeze is drained from the heating system.

To do this, remove the cover from the expansion tank, then unscrew the drain bolt at the bottom of the engine. You can also disconnect the cooling tube of the throttle assembly and connect a hose instead, through which the coolant can be drained into a prepared container.

We change the radiator without removing the dashboard

This procedure is based on experience a large number drivers who have already replaced parts without complex dismantling of the instrument panel. The work can be broken down into several stages:

Replacement by car with air conditioning.

The radiator of the stove on a Chevrolet Niva with air conditioning, due to the design, is located somewhat differently than in the previous case. Therefore, in order to change it, it is better to resort to some tricks.

Also, replacing the radiator of a Niva Chevrolet stove with air conditioning without removing the instrument panel will require replacing the evaporator. Therefore, in some cases, car owners prefer to make repairs with the removal of the tidy. Despite the fact that this method is more complicated, it allows you not to violate the tightness of the air conditioning system so that there are no costs for refueling with freon.

The work can be broken down into several main stages:

It is necessary to disconnect the battery, then drain the antifreeze from the cooling system into a special container. To remove all residual fluid, you can blow out the expansion tank.
The mounting bolts of the radio are unscrewed, then it is removed together with the slide. Self-tapping screws are unscrewed that hold the panels and the instrument panel. Then press the latches and slightly take the panel away so that it comes out of the grooves.
To simplify the reassembly process, you can mark all the chips and connectors with a marker or attach beacons from electrical tape. Then the side shield, the steering wheel cover, the backlight connector are removed.
The steering column is removed together with the strut
The fan is unscrewed, then you can proceed to dismantle the stove together with the air conditioner unit

It is important to remember that replacing the stove radiator will require disassembling a significant part of the front panel, therefore, so that during assembly there are no unnecessary parts left and the system works properly, you must adhere to a clear order during reassembly and, if necessary, remember the location of the fasteners.

After dismantling, it is necessary to check the radiator and all inlet pipes for leaks. If possible, it is necessary to replace all the pipes that are damaged or appearance raises suspicions so as not to return again to such a long repair procedure.

The assembly is carried out in the reverse order. After all the elements are installed in their places, the system is filled with coolant and for the first few days it is necessary to monitor its level. If all the work was done correctly, then the interior of the car will get rid of antifreeze smudges for a long time and heat will return and Fresh air without foreign smell.
