Coolant Hose 11537572158 For BMW E46 E87 E83 E90 E91

The water pipe connecting the automobile thermostat to the cylinder head is the pipe connecting the thermostat and the engine cylinder head, and its main function is to guide the coolant from the engine cylinder head to the thermostat for temperature adjustment.

Specific functions include:

1. Cooling the engine cylinder head: The engine cylinder head is an important part of the upper part of the engine, which is responsible for sealing the cylinder and valve mechanism. Through the water pipe connected to the cylinder head through the thermostat, the cooling liquid can flow through the cylinder head of the engine, absorb the heat generated by the engine, prevent the cylinder head from overheating, and keep the engine in a suitable working temperature range.

2. Transmission of temperature signal: The water pipe connecting the thermostat to the cylinder head also plays the role of transmitting temperature signal. When the coolant flows through the engine cylinder head, it will absorb the heat of the cylinder head and the temperature will rise accordingly. This temperature signal will be transmitted to the thermostat through the water pipe, and the thermostat will judge whether it is necessary to adjust the flow of coolant according to the temperature signal to maintain the suitable working temperature of the engine.

3. Maintain the circulation of the cooling system: the water pipe connecting the thermostat to the cylinder head connects the engine cylinder head and the thermostat, so that the coolant can circulate between them. After absorbing heat in the engine cylinder head, the coolant flows to the thermostat through the water pipe, and then flows back to the engine for circulation after being adjusted by the thermostat, so as to keep the normal operation of the cooling system.

In a word, the water pipe connected to the automobile thermostat cylinder head plays an important role in cooling the engine cylinder head, transmitting temperature signals and maintaining the circulation of the cooling system, ensuring the engine to run in a suitable temperature range and improving the performance and life of the engine.
