The cooling system of a modern car is closely related to interior heating. In order to warm up the interior of the vehicle faster, it is necessary to temporarily cut off the cooling radiator. This problem is successfully solved by the thermostat. As soon as the temperature in the small circuit reaches 80 … 92 ° C, the valve begins to open, expanding the line. After the coolant has cooled down, the valve closes again. With timely replacement of antifreeze, the thermostat's service life can be extended up to 10 years. And then the owner has a question of replacing this important node. Our experts recommend that you pay attention to several points when buying.
Symptoms of a faulty thermostat. In order for the engine to please the motorist for a long time, it is important to maintain the temperature regime in the specified range. Replacement of the thermostat is required immediately in the following cases:
- overheating of the motor due to a permanently closed circuit;
- the stove does not heat up even when the engine is running for a long time due to the constantly open thermostat.
To finally make sure that the unit is broken, you need to touch the cooling system pipes that connect the thermostat to the radiator.
Types of thermostats. In modern cars, there are several varieties that differ in design.
- Two-valve thermostats are used in engines with high pressure in the cooling system. When the antifreeze is at medium temperature, one valve opens. When the high temperature is reached, the second valve is activated.
- Side valve models are installed in simple cooling systems. Additional elements allow to reduce the temperature difference in the circuit.
- Manufacturers use aluminum or plastic to make the thermostat housing. The metal knot looks more reliable, but it costs more.
- Modern thermostats are equipped with electronic heating and temperature sensors. These additional options allow you to react in a timely manner to an increase or decrease in temperature.
Thermostat selection options. To choose a replacement for a failed node, you can resort to one of two options.
- It is very easy to buy a thermostat by VIN code. Alternatively, you can set several parameters of the car (make, model, year of manufacture, engine, etc.), after which the seller will offer the node found in the catalog.
- Owners of used cars often have to deal with the fact that the purchased spare part does not correspond to the “original”. One of the reasons is the completion of the cooling system by the previous owner. Only an experienced auto mechanic can deal with this problem.
- There are times when the same model has different designs. Then you should be guided by the markings that are on the old thermostat.
