The radiator hoses connect the radiator to the cylinder block and circulate coolant throughout the engine to remove excess heat. An upper hose connects the top of the radiator to the top of the engine. A lower hose connects the bottom of the radiator to the water pump of the engine, which keeps coolant flowing through the system. Since the radiator hoses are constantly exposed to extreme under-the-hood conditions, it will inevitably wear and develop tears and cracks. YHTAUTO radiator hoses provide a reliable replacement solution for you.
