Note:

If the radiator does not fit completely into the container, check it sequentially from all sides.

16. Install the radiator on the car in the reverse order of removal, first placing the lower mounting pads on the radiator pins and inserting the upper mounting bushings into the brackets.

17. Install the electric fan and all removed parts on the Lada Granta car in the reverse order of removal.

18. Add coolant as described here (for 8-valve engines) or here (for 16-valve engines).

Replacing the cooling radiator on Grant

An engine radiator is a special design that is part of the cooling system of a vehicle engine. Its main function is to reduce the temperature of the coolant, which circulates through many cells located in this very radiator. During operation of the engine radiator, the liquid in it is under pressure and in cases where depressurization of this element occurs, a leak forms, and the above pressure decreases significantly. In most cases, the engine radiator cannot be restored, so it is simply replaced.

Replacing the cooling radiator on a Grant with your own hands

Below you can find instructions for changing the radiator of the vehicle engine cooling system:

1. First of all, you should drain the coolant that is in the engine.

2. Next, you need to dismantle the electric fan that belongs to the radiator.

3. Now you need to squeeze the antennae of the hose clamp that is connected to the expansion tank and disconnect it.

4. The next manipulation should be to remove the hose from the fitting located on the radiator.

5. Absolutely identical manipulation must be performed on the hose responsible for supplying coolant.

6. Now, for the third time, you need to manipulate the tendrils of the clamp fastening, this time the actions should concern the hose, which is responsible for draining the coolant.

7. Next, you need to unscrew the two fastening nuts, which are located on the top of the radiator. Along with the nuts, you also need to remove the washers that are located under them.

8. It's time to dismantle the radiator itself. To do this, this element of the cooling system must be tilted towards the engine and removed from the engine compartment.

9. Now you need to remove from the vehicle body two rubber cushions that protected the radiator of the cooling system from unnecessary shocks.

10. Next, you should carry out a visual inspection of the rubber cushions, and if they are damaged, replace them.

11. The next step is to dismantle the rubber-metal bushings.

12. Next, install a new radiator and reassemble the structure in the reverse order.

Let us recall that in the previous article we looked at how to replace the timing belt on a grant with your own hands. This repair can be performed in a garage, provided you have all the necessary tools.

What to do if you doubt that the radiator of the Lada Granta engine cooling system is faulty?

Sometimes, the radiator may seem to be fully functional upon external inspection. To make sure there is a leak in it, you must close all the holes into which the pipes are supplied, and connect a hose to one of them, through which compressed air with a pressure of 0.1 MPa will be supplied. Next, place the radiator in a tank of water for thirty seconds. If bubbles appear, then you can be sure that this radiator is leaking.

Recommendations for the selection of parts and components

The range is represented by domestic manufacturers, originals and high-quality analogues. The final choice is up to the owner of the technical device.

Service center technicians strongly recommend purchasing original parts. The service life and manufacturing quality of factory components are an order of magnitude higher than their analogues.

Before purchasing, carefully check the spare part catalog numbers with the actual data in the instruction manual. If necessary, get free consultations from service station specialists.

Lately it has become popular to order parts for subsequent installation directly in workshops. There are many advantages of this choice: prompt delivery, professional installation, quality guarantee.

Reviews

Positive
1.Mikhail: I have run over 80,000 km on my car, there are no complaints, the cooling system is working as normal. I follow the manufacturer's instructions - replace antifreeze every 75,000 km.
2.Vladimir: in two years of active driving, I replaced the thermostat once. I don’t consider this a significant breakdown, since this is a normal occurrence for domestic cars.
3.Kirill: The car is a year and a half old, I bought it at a dealership. There are no complaints, all mechanisms work as usual. Breakdowns happen, but they are not so significant and can be easily fixed on your own.
4.Gennady: after buying the car from the dealership, I immediately replaced the antifreeze with a new, imported one. Domestic is of low quality and quickly loses its properties.
5.Vasily: I am satisfied with the quality of assembly and manufacturing of the Lada Granta (16 valves). As for a domestic manufacturer, this is very good, it cannot be compared with Kalina, Priora. I fix minor damage myself.
6.Konstantin: within a year and a half of using the car, I replaced two clamps on the cooling system pipe. I don’t consider this a defect; it’s normal for Lada.
7.Victor: I’ve heard negative reviews about Granta, I think they are unfounded. You should always follow the instructions in the instruction manual, then everything will be fine.
Negative
1.Alexander: the radiator leaked at 39,000, corrosion formed, luckily I replaced it with a new one under warranty. After 15,000 km. The thermostat has failed. Lots of trouble with the Grant, it’s better to pay a few tens of thousands extra and buy a Renault Logan.
2.Vladislav: Two years have passed since I bought the car, and I have already had unscheduled repairs at a service station several times. The build quality is crude, many defects are not eliminated from generation to generation.
3.Igor: many components and assemblies do not maintain their service life and wear out prematurely.

Conclusion The average service life of the cooling system radiator on a Lada Grant is over 100,000 km. Provided you follow the manufacturer's recommendations and replace the antifreeze, no problems arise after 75,000 km.

A number of owners save on maintenance, buy cheap analogues, lubricants, liquids, as a result of which irreversible processes begin. The mechanisms fail and work unstably.

Replacement procedure

  1. After the engine has cooled, unscrew the coolant expansion tank cap. The lid must be opened to equalize the pressure in the system.

Loosen the coolant drain plug on the engine block. The plug is located under the ignition unit.

Place a container to collect the liquid and unscrew the cap completely. Head plug for thirteen.

Press the lock and remove the power connector from the electronic gas pedal.

  • Unscrew the three nuts securing the gas pedal and remove it. Ten head nuts.
  • Press the latch and disconnect the power connector for the brake light button.
    Disconnect the brake pedal from the brake booster. To do this, remove the locking ring using pliers and remove the pin that fits through the hole in the pedal and the VUT bracket.

    Unscrew the two screws securing the plastic cover that makes access to the radiator difficult. Phillips head screws.

    Unscrew the three nuts securing the gas pedal bracket and remove it. Ten head nuts.

  • In the engine compartment, disconnect the power connector to the mass air flow sensor.
  • Loosen the clamp on the pipe going to the intake manifold. Next, disconnect the plastic pipe for the air intake and remove the air filter housing assembly. Clamp for a slotted screwdriver or 8mm head.
    Loosen the clamp and remove the pipe coming to the thermostat. Also remove the pipe connected to the pump. Head clamps for thirteen.

    Remove the insulation from the engine shield so that it can be reused.

    Cut or saw through the two aluminum tubes that go to the radiator. Cut off the tube that is closest as short as possible.

    Remove the radiator from its seat. When dismantling, it is best to place the brake pedal between the radiator tubes.

    Glue the seal onto the new radiator, just like it was on the old one. Most often, the seal comes with the radiator.

    Cut the pipes on the new radiator as shown in the photo below.

    Clean the seat and install the radiator.

    Place two clamps on the radiator tubes and lubricate the pipes with a sealing compound. Insert the pipes from the side of the engine compartment. Direct the heads of the clamps towards the radiator so that there are no problems with the plastic cover during installation.

  • Glue the insulation near the pipes.
  • Mount the gas pedal bracket and secure with three nuts.
  • Install the plastic cover for the radiator pipes and secure with two screws.
  • Connect the brake pedal to the vacuum booster.
  • Connect the brake light button power connector.
  • Install the gas pedal and secure with three screws. Also don't forget to connect the power connector.
  • Cut the pipes to size. Trim the pipes so that they are not strained and there are no kinks.
  • Fill the radiator with coolant.
    Lubricate the pipes with a sealing compound and secure them to the thermostat and pump.
  • Install the air filter housing and connect the mass air flow sensor.
  • Pass coolant through a sieve and pour into the system.
  • Start the engine and check connections for leaks.

How to replace a radiator on a grant with air conditioning

Removing the air conditioner radiator on a Lada Granta car is carried out to replace it with a new one or repair it, in most cases to restore the tightness of the system. To carry out repair work, you will need a Phillips screwdriver, eight-size wrenches and a ten-socket socket.

It is most convenient to carry out repairs on a vehicle mounted on an inspection pit or lifts. Do the following sequence of actions:

  • De-energize the vehicle by disconnecting the negative terminal from the battery.
  • Remove refrigerant from the system.
  • Then remove the front bumper.
  • We disconnect the connector with the power wires from the electric radiator fan of the air conditioner.
  • We disconnect the flanges of the high and low pressure pipelines from the radiator. Immediately after disconnecting, plug the holes to prevent dirt from getting into them.
  • We press the clamps and pull out the bracket with the radiator from the holders on the engine cooling radiator. Let's take it off.
    • Replace it, then install it in the reverse order, removing the pipeline plugs directly when connecting the pipes. Be sure to replace the O-rings with new ones and lubricate them with oil used for the air conditioning system.

    Notes:

    Replacing the cooling radiator on Grant

    Replacing the main engine cooling radiator on cars such as the Lada Granta is done in rare cases, and the main ones are listed below:

    1. The appearance of a radiator leak, which can be caused by excess pressure in the cooling system
    2. Damage to pipes, which most often occurs as a result of an accident

    If for these or other reasons you had to change the radiator, then for this repair you will need a tool such as:

    • heads for 7, 8, 10 and 13 mm
    • 17 mm wrench
    • ratchet handles or cranks
    • pliers
    • flat and Phillips blade screwdrivers

    Preparatory stage before replacing the radiator

    Any repair of the power plant cooling system requires draining the coolant. If you need to replace the cooling radiator, you will need to drain the liquid in full.

    How to remove the radiator, how to change it? We act like this.

    1. We place the Lada Kalina in the middle of a flat area.
    2. Taking a “10” size key as our “helpers,” we dismantle the metal protection sheet located under the engine sump. This is necessary so that the process of draining the antifreeze is carried out directly into the container, and not along the surface of the crankcase protection.
    3. Draining the liquid should begin after the Lada Kalina engine has cooled. This will eliminate the risk of hand burns.
    4. We continue the process by dismantling the air filter housing.
    5. To gain access to the drain plug on the engine block, it is necessary to remove the ignition coil. To do this, you will need to de-energize the network by removing the terminals from the battery. It is also necessary to remove the high-voltage wires. The coil fastener is unscrewed using a hex key of size “5”.
    6. The plug on the block is unscrewed if you use the key at “13”.
    7. Don’t forget to first place a container of the appropriate size under the drain hole.
    8. After waiting for the antifreeze to completely drain, we move the container to the radiator.
    9. Disconnect the lower hose and continue collecting the refrigerant in the same container. The liquid will come out of the system more readily if you open the cap on the expansion tank.
    10. Having completed the “draining event”, we return the cylinder block plug to its original place, tightening it to the required torque.
    11. Now, using a suitable screwdriver, remove and tighten the clamp securing the system pipe to the fitting of the throttle assembly heating unit. This is necessary to bleed air from the circuit while charging refrigerant.

    The replacement of the cooling radiator is complete.

    Replacing the radiator insert on models with air conditioning

    Replacing the air conditioner radiator on Lada Kalina

    The sequence of actions is as follows

    1. Remove the car bumper.
    2. Pour the antifreeze into a container prepared in advance.
    3. Disconnect the radiator fan terminals.
    4. Remove the pressure pipes and plug them to prevent dirt from entering.

    • Press out the plastic fasteners of the cooling system and remove the air conditioner radiator from the car.
    • Installation of a new element is carried out in the reverse order.

      If it is necessary to install a new element, the plastic line plugs are removed only immediately before installing it on the machine.

      On Lada Kalina, replacing the radiator is quite simple. The procedure does not require highly specialized tools or special pullers. Also, there is no need for deep knowledge of the design of the car - for the whole process, it is enough to have “direct hands” and an understanding of the principles of car design.

    Radiator dismantling in Kalina

    To remove the designated assembly and related components, you will need to use the following tools:

    • wrench "10" (socket type);
    • pliers with thinned grips;
    • Phillips screwdriver;
    • If the Lada Kalina is equipped with an air conditioning system, then we additionally stock up on a set of Torx (star profile).
    1. Disconnect the power connector from the system fan.
    2. Let's dismantle this unit. It is held on the radiator with 4 bolts. To unscrew them, you will need to use a “10” key. Extraction is carried out in the upward direction.
    3. Next, we move on to removing the pipes from the radiator fittings. We loosen the clamps using pliers or a screwdriver. We use the same wrench to unscrew the two nuts that hold the radiator assembly in the seat.
    4. Now we tilt the product slightly towards the engine and lift it up.

    When dismantling the unit on a Lada Kalina equipped with air conditioning, you will need to resort to removing additional components that are directly attached to the radiator. To carry out this activity, you should stock up on a key with an asterisk profile.

    You need to unscrew 4 screws. During dismantling, look towards the lower radiator cushions. They can either be removed along with the product or left in the landing niches. Experts recommend removing these support elements to assess their condition. It would also be useful to remove the rubber-metal bushings present on the body of the LADA Kalina radiator unit. It is better to replace them with new analogues.

    Eliminating air jams

    The design of the cooling system in the VAZ-1118 has one unpleasant drawback - the tendency for the circuit to become airy. This can lead to overheating and engine damage. Here we recommend resorting to minor system upgrades. You need to act when the liquid is drained.

    1. First we replace the thermostat. Instead of a standard product with five holes, we install a component with six such holes.
    2. We add a refrigerant filter to the circuit.
    3. We install a shut-off valve on the pipe leading to the stove.

    These actions are not capable of radically transforming the system. Experienced owners of LADA Kalina have moved further in this matter. They add steam exhaust pipes, install a forced fan activation button, etc. To install the designated outlet, the diagram looks like this: we cut a tee into the pipe leading to the expansion tank. It is connected through a separate hose to the pipe of the throttle body heating unit. We place the second tee in the return from the radiator of the heating system and connect it with an expansion tank. Now you know how to remove, as well as how to change the radiator, and fix other problems yourself.

    Replacing the stove radiator on a Lada Granta with your own hands + video

    Lada Granta has become a really popular car. And, in many ways, this happened thanks to the affordable price and good components. For example, the stove installed on the Lada Granta is quite good, as it warms up the interior to the required level very quickly. AvtoVAZ engineers did a very good job on this issue, since for our harsh winters the issue of high-quality heating of the interior is very relevant.

    Installation of a new Lada Granta radiator

    When buying a new radiator, you need to understand that it must be either original or very close to the original in its characteristics.

    Car enthusiasts have to console themselves mainly with a radiator heater for the Lada Granta Luzar. In general, he performed well. Especially with the use of special additives that seal the liquid supply channels. The new generation of radiators has features in the fastenings; they consist of two parts and are assembled together with three self-tapping screws.

    The new radiator will fall into place correctly if, after purchase, you carefully cover it with foam rubber around the perimeter, after which a small window of the required format is cut, somewhere at the bottom of the stove body. Thanks to these manipulations, the new radiator should fit perfectly into place. Next, the entire assembly proceeds in reverse order.

    We dismantle the radiator of the Lada Granta stove

    This radiator eventually leaked into the car interior. And antifreeze vapors are harmful!

    Despite the fact that there are usually no complaints about the quality of the stove, breakdowns can still occur. If you focus on the radiator, it may clog or leak. In any case, you need to immediately begin dismantling the stove, after which it will be possible to inspect it in detail and understand the causes of the breakdown.

    Most of the work will have to be done on the top of the engine compartment, as well as from inside the car. In fact, in this case we will not need a pit, a jack, or a lift. Just keep in mind that access to the engine compartment will be extremely difficult.

    1. To begin, unscrew a couple of clamps that secure the heater pipes to the heater radiator. This frees them up so we can remove the pipes completely.

    2. Now we will have access to draining the coolant from the radiator. Naturally, you will have to take care in advance of the container where this liquid will be drained.

    3. If possible, we move the pipes to the side. In principle, most of the work in the engine compartment is completed here.
    4. Next comes work from inside the car. Near the handbrake you can find one self-tapping screw that secures the tunnel, as well as another self-tapping screw for fixing the parking brake housing. Unscrew them completely. In addition, on the driver's side and on the passenger's side there will be two more screws that secure the tunnel on both sides.

    One self-tapping screw under the handbrake tunnel

    Unscrew the two screws. One is visible in the photo, the second is to the right, closer to the gearshift knob

    Three pedal mounting bolts

    Gained access to the heater radiator pipes

    We saw off the radiator tubes to remove it

    Installation of a new Lada Granta radiator

    The new radiator must be original or at least compatible with it in size and technical parameters.

    We carefully cover its perimeter with foam rubber, after which we begin to work with the window in the stove body.

    Carefully cut a small window of a suitable size, closer to the bottom of the stove body.

    After this, the new radiator will fit into place very well. All other parts are assembled in reverse order.

    Selecting a new heater radiator (verified articles)

    A model specifically for the Lada Granta Luzar under the symbol LRh 0190b would be a good fit for the role of a standard heater radiator.

    It is completely made of aluminum alloy, and the price of this radiator is about one and a half thousand rubles. In addition to the Lada Grant, it is also suitable for installation in the second version of the Lada Kalina.

    In general, so far, alternatives are rarely found on the domestic market. So car enthusiasts have to be content with this radiator. However, it performs quite well, especially if you do not use special additives to “repair” it, which seal the liquid supply channels.

    Radiators of the so-called new type are characterized by mounting features. In addition, such radiators are not solid, but consist of two parts. They are assembled together using three self-tapping screws.

    As for the “old” radiator model, it has a completely solid structure. However, most of the fastening elements are the same as the new type, so installing any of them should not lead to any difficulties.

    Replacing the Grant stove radiator

    Introduction

    Keeping your car warm and dry is the key to comfortable travel in any weather. The Lada Granta is capable of giving such sensations, but when in cold weather the heater radiator begins to leak or becomes completely clogged, making it impossible to warm up the car interior, then driving such a car turns into a test.

    This article will discuss replacing the heating radiator on a Lada Granta car. It describes in detail the reasons for its failure and how to replace the stove radiator on a Grant without much difficulty and extra effort.

    Grant stove radiator

    The location of the heater radiator on the Grant is not convenient for replacing it. To remove the radiator without damaging it, you will have to dismantle the dashboard, which can take a lot of time and labor due to a trivial problem that can be solved in an hour in other cars.

    The radiator is located under the dashboard in its central part at the driver’s feet. Its pipes are hidden behind the decorative side panel trim. This location of the radiator makes it a little difficult to access it when replacing it, but if you use the correct replacement instructions, then removing and installing the radiator yourself will not be difficult.

    Why is cold air blowing from the stove?

    It often happens that cold air starts blowing from the Granta air ducts instead of warm air. This happens due to:

    • Radiator clogged;
    • Low antifreeze level;
    • Faulty thermostat;
    • Faulty stove damper;

    If you observe symptoms of a cold heater in your car, then you need to check the above description of the cause of this ailment.

    How to identify a clogged radiator

    Checking the radiator is a fairly simple task that anyone can do. To do this, you need to check the circulation of fluid through the radiator. If the circulation is normal, then both radiator tubes will be hot, but if the inlet tube is hot and the outlet tube is cold, this indicates that the radiator is clogged from the inside.

    A clogged radiator can be washed or, at best, replaced with a new one.

    Cost of Lada Granta heater radiator

    Below is a current list of prices for heater radiators grants.

    Types of Grant stove radiators

    There are two types of radiators: with soldered pipes (factory radiator) and with removable ones.


    Factory radiator with permanent pipes

    The manufacturer produces radiators with non-removable pipes, that is, in order to dismantle it without removing the entire panel of the car, it is necessary to saw off the pipes coming from the radiator.

    It is best to purchase a heater core from Datsun On-Do. The dimensions of the Datsun radiator are no different from the Grant one, with the exception of removable pipes, which will greatly reduce the pain during installation.

    Replacement

    To replace the stove radiator, you will need to prepare the necessary tools, coolant and the radiator itself. By following our instructions, you can easily replace the heater radiator on a Grant without removing the panel.

    What you need to replace:

    • Coolant 10kg;
    • Container for draining coolant;
    • Phillips screwdriver;
    • Hoses 16mm 2 pcs (if the radiator is Grantovsky);

    Step-by-step replacement process

    It is necessary to remove the battery, the air filter box by pulling it out from the rubber dampers and remove the intake corrugation. You will need this to access the thermostat.

    We drain the antifreeze from the cooling radiator by unscrewing the plug in the lower right part of the radiator. To drain, you will need a container of at least 10 liters.

    Attention: It is necessary to drain the coolant when the engine is cold to avoid burns.

    Remove the connector from the electronic accelerator pedal and unscrew the pedal from the car body using a 10mm socket wrench. Then remove the pedal from the studs.

    Unscrew the screws securing the radiator cap with a 6 mm wrench and remove it.

    We remove the radiator pipes and lower them down so that the remaining antifreeze drains.

    Now you need to press down the brake pedal; to do this, remove the cotter pin that secures the pedal and press on it when we remove the radiator.

    If the radiator is not dismountable, that is, the pipes are not removable, they must be sawed off with a hacksaw. If the pipes are removed, they must be removed and pulled out of the holes in the engine shield.

    After removing the pipes, you can pull out the radiator by pressing the brake pedal down.

    We install the new radiator in the same way, pressing down the brake pedal, first removing the pipes from the radiator and installing them after the radiator is placed in its seat.

    If the radiator is not prefabricated, then the pipes can be sawed off and the connection can be made on the hoses.

    Adviсe

    Antifreeze leaked into the cabin

    To prevent problems with the heater core, you need to carefully monitor it. For example, from the first days of buying a car, periodically look under the car to see if there are dark spots there. And in the engine compartment it would be a good idea to observe the condition of the cooling system hoses. If you notice traces of antifreeze in any of these places, you need to immediately seek help, or carry out repairs yourself.

    If possible, the hoses for connecting the heater radiator should be replaced with new ones, having coated the connection points with sealant. But some do not agree with this opinion. After all, sealant from the hose can get inside the cooling system and cause damage to the pump. As a result, the timing belt will break and the valves will meet the pistons.

    How to change the heater radiator on a grant?

    Replacing the Lada Granta heater core

    The Lada Granta stove often does not heat up, especially in cars with fairly high mileage. To understand why the Lada Granta stove does not blow warm air, you first need to understand the structure of the entire heating and ventilation system. For clarity, we will add to our article a photo of parts of the car’s heating system and tell you where the stove and other ventilation elements are located.

    The main elements of the Lada Granta heating system - stove, fan, air ducts, heater radiator - are located under the dashboard (device panel). But if you don’t need to disassemble much to remove the fan (it’s enough to remove the glove compartment lid), then to remove the heater radiator you will have to completely remove the dashboard (Lada Granta panel), and this is quite labor-intensive work.
