Why Replace Your Radiator Hose?

Over time, rubber radiator hoses harden, crack and deteriorate — particularly at the connection points where heat and pressure cycles are most intense. A failing upper radiator hose can cause coolant leaks, engine overheating and potential head gasket or turbo damage if left unaddressed. Replacing a worn hose is one of the most cost-effective preventative maintenance steps for any diesel 4WD.
