The thermostat is a valve that controls the flow path of the coolant. For an automatic thermostat, usually containing the temperature sensing component, by expansion or cold shrink to open, turn off the air, gas or liquid flow.

What is the fixture, where is the thermostat installed?

Generally installed in the water pipe engine side, is in the cylinder head, open the water pipe by the engine side, there is a fist-sized, usually two bolts fixed metal pieces, it can be opened to see the normal car Are more than 85 degrees above the water temperature to open, the following closed, but the specific depends on what your car, different car water temperature is not the same, the temperature of the china auto thermostat is not the same.

Experts say the thermostat is a valve that controls the flow path of the coolant and is an automatic thermostat that usually contains a temperature sensing unit that opens and closes air, gas, or liquid flow by thermal expansion or shrinkage. The thermostat can automatically adjust the amount of water entering the radiator according to the temperature of the coolant and change the circulation range of the coolant to adjust the cooling capacity of the cooling system to ensure that the engine is working in the proper temperature range.

Since china auto thermostat is so important, how can a check be made once the thermostat has a problem? Zhengzhou Wantong car school expert teacher said the thermostat detection method there are two, that is, after the car inspection and removal check. The following one by one.

The method of inspecting the thermostat

1, the engine after the start of the inspection: open the radiator water tank cover, if the cooler coolant cool, indicating that the thermostat is working properly, otherwise, said the thermostat work disorders. When the coolant thermometer indicates below 70 ℃, if the coolant inlet pipe if the coolant flow, coolant warm, then the thermostat main valve closed lax, so that the coolant too early cycle.

2, the coolant temperature after the check: the initial work of the engine, the coolant temperature rise quickly; when the coolant temperature meter indicates 80 ℃, the heating rate slows down, then the thermostat is working properly.

In the coolant temperature table indicates 70 ~ 80 ℃, open the radiator cover and radiator drain switch, feel the coolant temperature by hand, if the hot instructions that the thermostat work properly; if the radiator water cooler temperature is low, And the radiator in the water chamber into the water pipe without coolant outflow or outflow, indicating that the main thermostat valve can not open.

Check the method after the china auto thermostat is removed.
