COOLING SYSTEM: THERMOSTAT HOUSING
The thermostat is found inside what we call a thermostat housing. This encasing will connect to the engine and radiator hoses and assist the thermostat is regulating coolant flow to the radiator. The housing replacements will often come with the thermostat pre-built in. Replacing the thermostat is strongly suggested whenever replacing a radiator. Given some housings include the thermostat, you may want to replace the entire unit.
