Thermostat Housing 11118619408 For BMW F20 F21 F30 F34

When the thermostat cover of an automobile fails, the following problems may be caused:

1. Engine overheating: The main function of thermostat cover is to control the pressure and temperature of cooling system. If the thermostat cover fails, the pressure or temperature of the cooling system may be too high, which may lead to overheating of the engine. An overheated engine may damage seals, increase friction and wear, and even lead to engine failure.

2. Coolant leakage: The sealing ring or valve on the thermostat cover may be worn, aged or damaged, resulting in coolant leakage. Coolant leakage will cause the cooling system to lose pressure, reduce the cooling effect, and then lead to overheating of the engine.

In order to inspect and repair the automobile thermostat cover, the following steps can be taken:

1. Check the condition of the thermostat cover: Check whether the thermostat cover has cracks, deformation or other obvious damage. If problems are found, the thermostat cover needs to be replaced in time.

2. Check the sealing ring: Check whether the sealing ring on the thermostat cover is intact. If the sealing ring is aged, worn or damaged, it may lead to coolant leakage. The sealing ring needs to be replaced.

3. Check the valve: Some thermostats are equipped with valves to control the pressure of the cooling system. Check whether the valve works normally and whether it is blocked or damaged. If the valve fails, the cooling system pressure may be too high, and the thermostat cover needs to be replaced.

4. Check coolant leakage: Check whether there is any sign of coolant leakage. You can observe whether there is coolant leakage under the ground or use a pressure test tool to detect whether there is leakage in the cooling system.

If the above methods can't solve the problem, it is recommended to seek professional automobile maintenance service. Professional technicians can determine the cause of thermostat cover failure through more in-depth inspection and diagnosis, and carry out corresponding maintenance or replacement of thermostat cover. In the process of maintenance, the thermostat cover and sealing ring with original factory or reliable quality should be selected to ensure the normal operation and safety of the cooling system.
