EGR return hose

The main function of the EGR return hose for engine accessories is to discharge hot water from the engine, ensuring that the engine does not overheat. When the engine is working, a large amount of heat is generated, which needs to be dissipated through the cooling system. The cooling water circulates inside the engine, absorbs heat, and is discharged through the EGR return hose to maintain the normal operating temperature of the engine and prevent overheating and damage.
