LR018275 Radiator hose is a key component in the engine cooling system. It connects the radiator and the engine and is used to circulate coolant between the two. After the coolant absorbs the heat generated by the engine, it flows into the radiator through this hose to dissipate the heat, and then flows back to the engine, forming an efficient heat dissipation cycle, thereby keeping the engine within a safe operating temperature range. The hose is usually made of multiple layers of rubber and reinforced fibers to withstand the high temperature and pressure inside the cooling system.
