For the past two days I've noticed that my temp dial is staying right on the C and not moving to half way between C and H. The problem is that it's not consistently staying on C. If I shut the car off for a minute or so and then restart it the temp needle will occasionally rise to the normal half way point.
I'm wondering if there is anything I can check first to see what the cause is? I've tried to search but not found anything conclusive. I've read some people say it could be an air pocket but I've not done any changes to the car for a long time so I'm not sure how an air pocket could be the symptom.
Is the replacement of the thermostat a tricky job? Does anyone know of the part number I'd need to order to replace it? Where approximately is this located?
Thanks for help or suggestions!
