My temperature gauge is really irratic! One minute it's off the guage hot, the next it's in the normal range and sometimes it doesn't register at all.
I recently had the wp,thermostat, belts, seals and tensioner changed. They also changes the sensor that goes into the thermostat housing.
Any suggestions as to what the problem might be??

 

Was it for that exact same problem you're having now?

If not, was the air from your cooling system bleed correctly?

 

These parts were changed because it was overheating, plus I just passed the 130K mark.
Regarding the coolant system bleed, wouldn't the air pocket bleed out by itself after a little while?

 

I have the same problem and have no idea, im not sure if i wanna pay to get it fixed, but i dont want to ruin my engine my having it overheat.
