Poor output from the heater and/or engine overheating can be caused by air left in the cooling system after the cooling system has been serviced. Our technicians tell us the proper coolant fill procedure should be used to prevent this problem from occurring.

    purged cooling system to replace radiator. Since doing so engine overheats immediately upon starting. Temperature gauge on panel says in normal operating range. New gauge shows going over 200 degrees? Lower radiator hose doesnt get hot till 190 degrees. Replaced thermostat and original temp sensor. have not yet figured out what to do.

    engine overheating without notice. temp gauge does not reflect overheating.
