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.

    Radiator fans appear to not running proper, one runs but the other fails to start? one mechanic mentioned the second fan only runs when the AC is energized? it this correct? and what is the correct temp level and/or max? mine gets to almost half the temp.

    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.
