Coolant Hose 11538645479 For BMW N20 F25 F26 E84

Thermostat is an important component in automobile cooling system, which is used to control the flow and temperature of coolant. It is usually installed on the water inlet pipe of the engine, and it can adjust the flow and direction of coolant by sensing the temperature change of the engine to maintain the normal working temperature of the engine.

The water pipe connecting the thermostat needs to have the following characteristics:

1. High temperature resistance: The water pipe connecting the thermostat needs to be able to withstand the flow of coolant at high temperature without deformation or rupture. The coolant will reach a high temperature when the engine is running, so the water pipe needs to have good high temperature resistance.

2. Corrosion resistance: The coolant contains certain acidic substances and impurities, which may corrode water pipe materials. Therefore, the water pipe connected to the thermostat needs to have good corrosion resistance and can resist the corrosion of the water pipe by corrosive substances in the coolant.

3. Sealing: The water pipe connected to the thermostat needs to have good sealing performance to ensure that the coolant will not leak or leak. Coolant is an important part of the cooling system. Leakage or leakage will lead to insufficient coolant and affect the normal operation of the engine.

4. Pressure resistance: The water pipe connecting the thermostat needs to have enough pressure resistance to withstand the pressure change in the cooling system. The coolant in the cooling system will be affected by the pressure when the engine is running, and the water pipe connecting the thermostat needs to be able to withstand this pressure without cracking or leakage.

5. Flexibility: The water pipe connected to the thermostat needs to be flexible to adapt to the vibration and movement of the engine. The engine will vibrate and move when working, and the water pipe connecting the thermostat needs to be able to follow the movement of the engine without cracking or leakage.

In short, the water pipe connecting the thermostat needs to have high temperature resistance, corrosion resistance, good sealing, sufficient pressure resistance and certain flexibility to ensure the normal operation of the thermostat and effective control of the cooling system.
