Drain about 1 gallon of coolant from radiator Follow upper radiator hose to engine housing Remove housing - make note how thermostat is installed Clean both surfaces Install new thermostat and gasket Re-fill coolant slowly to prevent "airlock" Start engine and check for leaks Run engine to normal operating temperature with heater on Check coolant level
