The radiator transports the heat from the engine’s coolant to the outside air while the radiator cap seals and pressurizes the cooling system.
Common signs of wear are coolant leaking, engine overheating, rusting, and physical damage.
The radiator should have the bugs, leaves and other environmental debris removed from the front of the radiator. Failure to remove debris can seriously block air flow and reduce cooling efficiency. Anytime the instrument panel-mounted temperature gauge illuminates immediately visit your local Custom Complete Automotive for an engine coolant system diagnosis.
The radiator cap should never be removed while the engine is hot. If the cap is not properly secured there may be a lack of pressure in the cooling system, vapor leaks, etc.
Servicing your coolant system at regular intervals can help early detection of leaks, corrosion, or a worn cap gasket.
