Hello family,
Well tonight I had an hour drive home which was 45 min of highway driving and I realized that my car never reached full temperature.
This obviously sounds to me like a failed thermostat, but even though I was keeping a fairly constant speed the temp gauge kept fluctuating, some time it almost reached running temp but then never stayed there.
So I am wondering what are the chances that it is the coolant temp sensor over the thermostat and is there any way to tell which it is before I start replacing parts?
Also conditions tonight were normal: about 65 degrees, and I even drove with the heat on for a bit to see if it would cause the temp gauge to go up but it never did.
Any insight from the experts?
Thanks,
DM
