    My question is simple if the car is running fine but the temp reading on dash is below normal (12 o'clock position)operating position, is that a concern?
    Obviously not overheating, is there such a thing as underheating?
    Would it be the thermostat or the temp sending unit that might be needing replacement. Coolant was low a bit but topped it off and it is staying topped off but no change in not getting to needle on temp dash pointing straight up, a bout to the left.
