Replacing the radiator of the Renault Logan air conditioner; describe in detail

Replacing the radiator of the Renault Logan air conditioner - we describe in detail

If your Renault Logan had been deprived of this device, it would hardly have lasted long. The radiator is the main unit of the cooling system, thanks to which the engine runs smoothly, without overheating. Meanwhile, it is also subject to wear and tear and irreparable breakdowns. If this happens, our car service will quickly and inexpensively replace it.

Construction and meaning of the node

From the point of view of design, the stove is a special, most ordinary heat exchanger, which performs the function of transferring heat from the coolant to the environment. In this regard, it is practically no different from the main radiator, which performs a similar function. This particular radiator is connected to the cooling system in parallel. For this purpose, the design has special fittings through which the coolant (coolant) enters the stove and gives off heat to the passenger compartment.

The product is made in the form of oblong honeycombs. Such a design is considered classic, while it is precisely this design that allows the most efficient transfer of thermal energy from the coolant to the environment. Mandatory are the inlet and outlet valves, which are used to supply and return the coolant, respectively.

The main radiator operates in a large circuit, while the stove radiator operates in a small circuit. At the start of the car, the small circuit is started first of all, when the coolant flows from the engine to the small radiator and vice versa. Due to this, car owners can turn on the stove immediately after starting the engine.

Most models have a special expansion tank and steam outlet. They are necessary in order to remove excessively superheated water and generated steam. Many drivers ask a logical question - why can't you use the heat that is released from the main radiator? The fact is that the air that is blown into it is not purified in any way, therefore, it contains dust and other pollutants.

Having a separate radiator with fan and filter not only improves air safety and cleanliness, but also allows you to regulate the level of heat. It is possible to implement such a system based on a large radiator in front of the car, but it will be too complicated and ineffective. Also, do not confuse the radiator of the Renault Logan air conditioner with the heat exchanger for the oven. These are different parts in the car, while the latter has a capacitor in its composition, if you speak correctly.

Naturally, if the heating radiator is damaged, the stove will function with low efficiency or will not warm up the interior at all. Moreover, a coolant leak can cause a wide variety of problems. Ultimately, it will not be enough to cool the motor, which will lead to overheating and all the ensuing consequences. For example, overheating within 20 minutes can cause:

  • deformation of the cylinder head;
  • the appearance of cracks in the cylinder head,
  • the burnout of the cylinder head gasket;
  • the destruction of the inter-ring partitions;
  • destruction of oil seals.

In this regard, you should not be careless about stove breakdowns, especially if it is connected with the radiator itself.
