SAE J20 R1 EPDM Coolant System Hoses For Heavy-duty Application
The radiator coolant hose for the automotive cooling system is an important component in the automotive cooling system. It is mainly responsible for the circulation process of transporting coolant from the engine to the radiator and returning from the radiator to the engine. This process is essential to maintain the optimal operating temperature of the engine, prevent the engine from overheating, thereby protecting its normal operation and extending its service life.
The main function of the automotive radiator coolant hose is to promote the circulation of coolant between the engine and the radiator to achieve the purpose of heat exchange. When the engine is running, a large amount of heat is generated inside, which will be transferred to the radiator through the coolant flow, where heat exchange with the outside air is carried out to cool the coolant. The cooled liquid returns to the engine again to form a closed-loop cooling system. This circulation can not only effectively prevent the engine from overheating, but also help keep the engine within an ideal operating temperature range, thereby improving fuel efficiency and power output.

COOLANT CIRCULATION
Coolant hoses help circulate the coolant from the radiator to the engine and back. This circulation helps regulate the engine's temperature, preventing it from overheating.
