I was wondering if theres somthing wrong or if I'm being paranoid. I was driving around today in 105degree weather and I have my air on and the temp goes way up like the line b4 the red. When I'm driving it will go between the middle and that line b4 the red. When I shut off the AC the temp will go down and it stays in the middle. The car has 88K on it and I know i'm due for a waterpump and timing belt. Am I being paranoid??
