Should be located at the engine end of the upper radiator hose in a housing Drain about 1 gallon of coolant from radiator Remove housing Make note how thermostat is installed Clean both sufaces Replace thermostat and gasket Re-fill coolant slowly to prevent "air lock" Start engine Look for leaks Run engine to normal operating temperature with heater on Re-check coolant level
