Hi there, I just bought a 05 grand prix, happy with it so far I just was wondering what position the needle should be at when it gets up to temprature? It went up to a little over half way when I was idling waiting in line at the car wash, although I was on the highway before that and it never got that hot. Is it normal for it to get that high? It started to cool down before I shut it off at the carwash so I wasn't too worried about it but I am just paranoid I guess
