i have a 99 mark 1. temp gauge only goes about one third of way when car has warmed up. only when idling it does it go to half way and then fan kicks in and needle drops back to one third again. Heater works fine. engine performs very well. Is there a problem with the sender or the thermostat? if the engine is running cool will that do any harm?
