Fast and qualitative replacement of the radiator of the VAZ-2109. VAZ-2109: replacing heater radiator with own hands

Owners of VAZs of the Samara family know firsthand that one of the most vulnerable elements of the cooling system is the radiator of the heater. Too, it often goes out of order, or rather, flows. And the metal from which the radiator is made, seems to be nothing, and the heat transfer is not bad, but that's all. The benefit of the price for this part is acceptable, which allows you to make a replacement if necessary. But even here everything is not so smooth. The fact is that replacing the radiator of the VAZ-2109 stove involves dismantling and removing the control panel. At least that's what is stated in the user's manual of this car. We'll tell you how fast replacement of the radiator of the VAZ-2109 heater is carried out without disassembling the torpedo.

Symptoms of a malfunction

Most often, the stove declares its problem with the onset of cold weather. Most drivers for the summer period overlap the heater tap, stopping the flow of coolant into the radiator. With a decrease in temperature, car owners are starting to actively use the stove, and often encounter the appearance of damp spots of incomprehensible origin on the carpet under the glove compartment from the front passenger side. This is the first sign that the radiator stove has flowed.

Sometimes it happens that the visual flow can not be determined. The cooling liquid can simply leak into the heater housing, and already from there, evaporating under the influence of warm air, enters the interior through the deflectors of the ventilation and heating system.

And in either case, the salon will contain a specific smell, inherent in antifreeze or antifreeze. In addition, the leakage of coolant into the interior of the car can be accompanied by the formation of a white oily coating on the inside of the windshield.

If these signs are present, the VAZ-2109 heater radiator will need to be replaced, but before that, you should make sure that it was he, rather than the heater tap.

The reasons for the heat sink of the heater

Coolant leakage can be caused by the following factors:

• Factory marriage, allowed in the manufacture of a radiator;
• Depressurization of the device due to corrosive processes;
• Use of a poor-quality coolant whose composition contributes to corrosion;
• Mechanical damage to the heater.

Necessary Tools and Tools

Having carried out a preliminary inspection of the heating system and putting an exact "diagnosis", you can begin to prepare for repair. Start with the purchase of a new radiator heater. Today on sale you can find two types of these parts: copper and aluminum. The first are reliable and, if properly operated, can serve an average of five years. Of course, they are more expensive (1500-2000 rubles). Aluminum radiators are slightly cheaper (about 1000 rubles), however they serve half as much. There is another kind of heat exchanger from the same material (non-original), which is best not to buy, especially if you are making a machine for yourself. They produce them incomprehensibly where, but they cost about 600 rubles.

In addition, the independent replacement of the VAZ-2109 heater radiator implies the use of the following tools and means:

• set of wrenches;
• Cross and slotted screwdriver ;
• Capacity of about 5 liters (for draining the coolant);
• Clean rag.

It is also desirable the presence of a male helper, who will both physically and morally support, because the upcoming procedure is not particularly fascinating.

Preparing the car

Before starting to repair, the car must be properly prepared for it. First you need to drain the coolant from the system. Warm up the engine to operating temperature and place the machine on a pit or on a flyover. Carefully open the radiator cap and the expansion tank cap. This is necessary in order for the coolant to drain faster. Now place a pre-prepared container under the drain plug, and only then unscrew it with a key. It may take 7-10 minutes for the whole OZH to leave the system.

Then you can proceed directly to the repair.

Replacement of the radiator of the stove on VAZ-2109: instruction

We will bypass the way of replacing the heater, which involves dismantling the control panel. Although it is considered correct and even registered in the manual, it can take away a lot of time and nerves from you. Let us dwell on the folk method invented and repeatedly used in our garages.

The first thing to do is to remove the front passenger seat, since it will interfere with our process. Next, shut off the heater tap and proceed to unscrew the screws that secure the control panel to the body on the right side. Do not forget to dismantle the glove box. After turning the screws that fix the panel to the right to the floor.

Check that all screws are unscrewed. To do this, try to lift the panel and pull it toward you. If something hinders this, then somewhere is not unscrewed. If the panel is moved, insert any object (bar, log, bottle) between it and the body, which would keep it in a raised state.

Replacement of the radiator of the VAZ-2109 begins with the disconnection of hoses from the nozzles. For this purpose it is enough to loosen the fasteners of the clamps with a screwdriver, and pull the hoses on yourself. Be prepared for the coolant to flow out of the radiator. A clean rag should always be at hand. After that, you can dismantle the radiator. We unscrew three screws on its cover, fastening it to the body. Now the radiator can be removed from the heater housing. The new part is installed in the reverse order.

But that is not all. Self-replacement of the heater radiator without removing the VAZ-2109 panel should result in a thorough check of the tightness of the connections. When the radiator is installed, do not rush the panel. Fill the coolant into the system, remember to tighten the drain plug, start the engine and warm it up. Moving to the interior, inspect the connection points of the hoses and nozzles, as well as the heater tap. If there is no leak, you can collect the panel.

By the way, it's possible to repair not only the VAZ-2109. Replacement of the heater radiator with their own hands in a similar way can be carried out on all "Samara", regardless of the height of the panel.

Some useful tips

Finally, here are some tips for the heater of your car to serve you as long as possible.

1. Having decided to replace the radiator of the heater, do not be stingy. It is better once to buy a quality original part than every year to mess with its repair or replacement.
2. Never use products of doubtful origin and composition as OLC.
3. Do not allow the radiator to remain idle for a long time without liquid. Even in the summer, at least once a month, open the heater tap to expel the coolant.
