Coolant Hose 11537585023 B For BMW  E70 E71

The water pipe connecting the automobile thermostat to the cylinder head plays an important role in the automobile cooling system. Its main functions are as follows:

1. Cooling the engine: The water pipe connected with the thermostat to the cylinder head leads the coolant out of the cylinder head of the engine, and then returns to the engine after being adjusted by the thermostat to help maintain the engine in a suitable working temperature range. This helps to prevent the engine from overheating or low temperature and ensure the normal operation of the engine.

2. Energy saving: Through the thermostat connected to the water pipe of the cylinder head, the coolant can reach the appropriate working temperature faster when the engine is started, reducing the energy consumption of the cooling system and improving the fuel efficiency.

3. Protect the engine: Proper working temperature is helpful to reduce the wear of engine parts and prolong the service life of the engine. The water pipe connecting the thermostat to the cylinder head plays a role in protecting the engine and ensuring the engine to run in the best working condition.

4. Improve thermal efficiency: Through the thermostat connected to the water pipe of the cylinder head, the coolant can absorb and dissipate the heat generated by the engine more effectively, improve the thermal efficiency of the engine and reduce the heat loss.

Generally speaking, the water pipe connecting the automobile thermostat to the cylinder head plays an important role in regulating the temperature of coolant, protecting the engine, saving energy and improving thermal efficiency, and is an indispensable part of the cooling system.
