Replacement radiator cooling grant 8 valves

Radiator replacement and stove repair Lada Granta

The engineering staff of AvtoVAZ worked very hard on the heating of the Lada Grant. The interior warms up very quickly and the temperature reaches the desired level. But, despite the high-quality performance of the stove itself, breakdowns sometimes cannot be avoided. For example, the radiator may leak or become clogged. For this reason, you need to understand the causes of the breakdown by dismantling the stove.

This type of repair eliminates the need for a jack, a lift, or even an inspection hole.

All the main work is done in the upper level of the engine compartment or inside the car; the only inconvenience is the difficulty of accessing the engine.

1. We begin the repair by unscrewing the two clamps that secure the stove pipes to the heater radiator. We remove the pipes completely.
2. We find a container for draining the coolant in advance and drain it.
3. At the end of the work in the engine compartment, we move the pipes to the side.
4. Inside the car, unscrew the self-tapping screw that secures the tunnel near the handbrake, and the other that serves as a clamp for the parking brake housing. We find and unscrew two more screws on the driver and passenger sides.
5. Using a screwdriver, you very carefully remove the cover of the gear shift knob. And at the same time the tunnel rises slightly, moving it to the left.
6. Unscrew the nuts securing the gas pedal and the stand under it.
7. A few more screws securing the casing are unscrewed, and the cover is removed.
8. Next we do the cutting. And only now the radiator is removed, the brake pedals, which interfere with this process, are clamped.

I would like to remind you that all these manipulations must be performed after first de-energizing the car, that is, you need to remove the terminals from the battery. Otherwise, you can get a short circuit that will damage all elements of the Lada Granta electrical network.

You can replace the radiator of the Lada Granta stove without removing the panel. To do this, it is necessary to cut off the pipes flush, extending beyond the body and interfering with the installation of the radiator. Remove the key from the pedal so that the pedal goes deep and does not interfere with the process. A long pipe with an internal diameter of 16 and an outer diameter of 24 is purchased and installed. Connects to pump and thermostat.

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.

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.

Features of operation of the Lada Granta stove

The Lada Granta has sensors on the dashboard that are responsible for the function of the stove, regulating power indicators, air temperature, and also has a regulator. The latter determines the priority direction of air flows:

• to the salon;
• on your feet;
• simultaneously into the interior and onto the glass.

There is also a horizontal range of motion handle that determines the source of air supply (from the cabin or from the street).

In a situation where a car is stuck in a traffic jam, and in front of it is a car with garbage, the “from the salon” variation is just a godsend for passengers and the driver. The same option is relevant in the case of accelerating the warming up of the car.

We dismantle the radiator of the Lada Granta stove

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.

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.

Installation of a new Lada Granta radiator

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

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)

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.

Reviews

Conclusion As practice shows, most calls to service stations are caused by a jammed thermostat on the Lada Grant. The reasons are different. The factor of manufacturing defects cannot be ruled out, but the fault also lies with the owner of the car.

Buy original spare parts, maintain your car in a timely manner - then the number of breakdowns will be reduced several times.

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.

Reviews

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.

Features of the Lada Granta stove

The dashboard controls that control the operation of the stove include switches marked with what power should be applied to the stove, as well as what kind of air it should blow - cold or hot. Near this switch there is another regulator that allows you to set priority air flow directions. This could be the windshield, interior, legs, or interior and glass at the same time.

Below these switches there is another handle with a horizontal range of motion. They can determine where the air will come from - from the cabin or from the street.

The “interior” option will be relevant if there are unpleasant odors outside or if you are faced with the task of warming up the car faster.

In recirculation mode, the car windows may fog up, so if you have air conditioning, we recommend turning it on. On many foreign cars, the air conditioner automatically turns on when the air recirculation mode is activated.

The rear windows can be heated with a special button located slightly below the handle.

The radiator must be replaced if a coolant leak is detected. In a workshop with special equipment, the radiator can be checked and repaired. You can also learn about the possibility of repairing the Lada Granta radiator yourself from the article “Radiator Repair”. Remove the radiator only when the engine is cold to avoid burns from hot coolant.

You will need: a 10" wrench (a socket head is more convenient), a screwdriver with a Phillips blade, and pliers with long thin jaws.
