over the last few days every time I've been out in the car I've had a coolant temp warning come up. The dash display creeps up to 110/120 on the dash, it drops back to 90 within about 20-30 seconds.
I've changed the temp sensor, I've check a return flow to the expansion tank.
Today I set the climate control to show engine coolant temp (51). It started off at about 14 and settled at 75. Driving home I noticed the dash temp gauge rise to 100 however the climate controll stayed on 75.
Any ideas on the problem!?
