Cooling Function and Replacement Information

The radiator transfers heat from circulating coolant to the air moving through the core. Correct coolant flow and an unobstructed fin surface support stable operating temperature under normal working conditions.

Leakage, damaged tanks, restricted fins or recurring high coolant temperature can indicate service is required. Hoses, pumps, thermostats, fans and other system faults should also be inspected before replacement.
