Before dismantling

In any car, including the Lada Kalina, replacing the cooling radiator implies that all the antifreeze has been drained from the system. How exactly you can get rid of old antifreeze was discussed in detail earlier. Well, now let us note once again that any manipulations can be performed after disconnecting the battery. It’s easier to unscrew and remove the “negative” terminal, which is what is done in practice.

It turns out that you first need to open the hood and disconnect the terminal, and only then can you proceed with subsequent operations. One of them will be removing the antifreeze, the other will be dismantling the fan.

Look again at exactly what the unit called “radiator” looks like. Before dismantling it, it is necessary to remove the fan with the casing.

The main thing is not to forget to disconnect the electrical connector. Also, you need to disconnect the pipes (two large and one thin). Of course, all this is done when there is no longer any antifreeze.

Tighten the battery terminal with a 10mm wrench

Owners of cars with 8-valve engines are a little luckier than everyone else. For them there is no need to remove the decorative trim that limits access to the engine. The plastic cover must be completely removed:

1. Having pressed the latch lever, disconnect the wire loop from the connector of the adsorber purge valve;

1. The metal plate fixing the valve is pryed with a screwdriver and removed;

1. The valve module, together with the attached hoses, is moved to the side;

1. You need to unscrew the oil filler plug;

1. The cover is dismantled as follows: by carefully pulling the part up, it is disconnected along with the fasteners.

The actions listed in the list are illustrated in the photo.

When to change the radiator

Regardless of location, design and intended purpose, radiators should be replaced when a leak is detected. Some types of coolers can be repaired. At the same time, specialists plug the damaged areas, which makes it possible to continue to operate the device. The disadvantage of the restoration procedure is a noticeable decrease in the efficiency of the part. The machine overheats faster and does not maintain operating temperature well.

Cases of decreased trafficability of highways are considered separately. When using low-quality antifreeze, sediment and scale may form. When sludge completely clogs the tubes, the part must be decarbonized or replaced.

How to remove a radiator (step by step instructions)

Let's assume the following requirements are met:

• The negative terminal is disconnected;

• There is no antifreeze in the cooling system;

• The 16-valve engine trim was removed.

Then, you can begin to dismantle the fan cooling the radiator. It may be necessary to remove the air filter module, which prevents free access to the engine compartment. The module is not completely dismantled, but simply taken to the side. Then you can remove the fan:

1. Disconnect the fan power connector;

1. Unscrew two metric 10 located on top of the casing;

1. The same bolt is located below. It needs to be unscrewed with a spanner;

1. The fan casing must be carefully guided upward (along the guide on the radiator), then disengaging the plastic tab.

Basic radiator malfunctions

Malfunctions of this Kalina unit do not occur so often and are the result of wear and tear due to natural causes of the car owner’s negligence. There are two most common types of problems:

• coolant leak;
• coking of cavities inside the radiator.

Leaks are dangerous because a decrease in coolant level leads to an increase in engine temperature. This leads to overheating and jamming of the motor. A leak of hot antifreeze can be dangerous. The fluid in the system is under pressure, a leak can form a fountain, and contact of hot antifreeze on exposed skin will cause burns.

Coking disrupts the antifreeze circulation process. As a result, the lower part of the radiator begins to cool, and then the entire heat exchanger. The liquid will not cool, causing the engine to overheat. In most cases, the cause of coking is ordinary scale. This happens when tap water is poured into the SOD. Less commonly, blockages occur due to mixing oil and antifreeze. In this case, the reason is the loss of tightness of the cylinder head gasket.

At an early stage, coking is difficult to detect. In advanced cases, mixing oil and antifreeze forms a consistency similar to jelly, which makes the heat exchanger tubes difficult to pass or completely impassable.

The radiator should be replaced if you find a fluid leak in your Lada Kalina 2. The radiator can be inspected and repaired in specialized services.

Take a 10mm wrench, a Phillips screwdriver, and a clamp with elongated thin jaws.

Warning

Carry out the removal procedure only on a cold engine.

2. On vehicles with air conditioning, unfasten the front bumper.

Note

The front bumper is disconnected because when removing the radiator of the cooling structure, it is also necessary to remove the condenser of the air conditioning structure. Because of the bumper, this procedure will become inaccessible as it blocks access.

3. Remove the electric radiator fan.

4. Squeeze the antennae of the breather fastening clamp, move the clamp along the breather,

5. Disconnect the breather and radiator fitting.

6. Squeeze the tendrils of the inlet breather fastening tie towards the radiator and slide the tie along the hose.

7. Remove the breather from the radiator pipe.

8. In the same way, disconnect the outlet breather and radiator.

9. On vehicles equipped with an air conditioning structure, disconnect the radiator of the cooling structure and the condenser of the air conditioning system. DO NOT disconnect the condenser and piping. Secure the condenser to the radiator frame.

Warning

Be careful when disconnecting the condenser from the air conditioner. Take it to the required distance so as not to damage the pipelines of the air conditioning structure.

10. Unscrew the 2nd fastening nuts to the upper cross member of the radiator frame,

11. Remove the nuts secured under the washer nuts,

12. Tilt the radiator towards the engine,

13. Remove the radiator from the engine compartment of Lada Viburnum 2.

14. Remove the 2nd lower fastening pads from the radiator, if any remain on the radiator mounting pins. If the cushions remain on the body, remove them from the lower cross member of the radiator frame.

Causes and symptoms of failure

In addition to the low quality of components and features of the car’s cooling system, the driver himself is often to blame for damage to the stove. Trying to save on consumables and operating materials, he significantly reduces the service life of the heater.

The main reasons for stove failure:

1. Using low-quality antifreeze. This can lead to contamination of all channels, which will significantly reduce heat transfer and circulation.
2. Faulty expansion tank cap. It causes increased pressure in the system, which will certainly lead to a “rupture” of the heat exchanger.
3. Manufacturing defects.
4. Using cheap antifreeze. Low-quality liquids are an aggressive environment for aluminum.
5. Use in the cold season as a coolant (coolant), water or low-density antifreeze.

A number of symptoms can indicate the presence of a stove failure.

Signs of damage to the heating radiator:

• drops of coolant on the passenger seat mat;
• the smell of antifreeze in the cabin and a “greasy” coating on the glass;
• low heating of the radiator, provided that the remaining heater elements are in good working order.

Replacing a stove radiator with your own hands: how to change the heat exchanger, how to repair or restore the radiator (140 photos and videos)
If the radiator device cannot be repaired, then you need to look for a new auto part. When searching for a part, motorists are often faced with a wide range of prices. For some, this fact is alarming. Others rush to buy cheaper goods.

You need to understand that the cost of a part is determined by the following factors:

1. Quality.
2. Year of manufacture of the car.
3. Radiator type.
4. Originality of detail.
5. State.
6. Manufacturer.
7. List and price of additional services (for example, delivery to the specified address or assistance in installation (replacement)).
8. The place where the purchase is made.
9. Implementer's pricing policy.
