Question

Hi guys, I have a question as I had a trip today with my z3, as I would drive the car faster, the temperature would rise, and when I would let off the gas the temperature would drop down again.

Is this symptom a sign of fridge problems, or water pump???
Thanks in advance

I would think that the thermostat is stuck open ?

It’s raising above the mid way point but not maxing out in the red, unfortunately whenever I would push the car more than 120 km it would rise, and when I would let go of the gas it would drop again. What strike me as odd is that it would over heat on the highway and not in traffic???
If it was the thermostat wouldn’t the temp rise in traffic??

The potential causes of a car overheating at motorway speeds is a stuck thermostat, a restricted radiator, or a kinked hose.
