Radiator Hose

Radiator Hose

Radiator hoses connect the radiator to the engine and carry coolant between them. There’s usually an upper and lower hose, both made of flexible rubber. They’re crucial for the flow of coolant, and if they crack, bulge, or split, they can leak or even burst—leading to sudden overheating. These hoses should be checked regularly for signs of aging and replaced when they get soft or show cracks.
