Gates 33038 cooling system components for the 1954-1967 Ford F-250 3.6L / 3.9L / 4.3L / 4.4L / 4.8L / 5.8L and other vehicles and equipment come as an OE Type engine coolant thermostat that opens and closes to control coolant flow and engine temperature.
- OEM fit, function and design for precise engine cooling
- Precise temperature control with a leak-free, OEM-equivalent fit
- Quality-controlled factory calibration keeps opening and closing accurate, regardless of pressure changes
Overheating, slow warm-up or a temperature gauge that swings can mean a thermostat is sticking. A failing water pump, a clogged radiator or a coolant leak can also be behind those symptoms, so track down the cause before you buy a thermostat.
It is listed for many vehicles and equipment across Ford, Dodge, Chrysler, Buick and other makes, including the 1966-1978 Dodge Charger 5.2L. Open the "Vehicles it fits" section to look up your exact model and engine.
