Please click the link for one second and look at the two pictures that thread started up with http://www.grandprixforums.net/tempe...mal-30982.html (cause I don't remember how to post pics I forgot lol) That is how my car's temperature used to act, but now in heavy traffic goes up to 210 like before and when I take the highway it won't drop, or it will drop a little under 210 mark, It was not the case before, months ago when I was in heavy traffic, temperature did go up to 210 but after entering the highway the temperature would drop to normal in few minutes (as you see in the first pic) Now it drops a little under 210 or drop more but it takes like 30 minutes.
Does it mean my thermostat is bad and need to be replaced at this point? If it helps, my car is a 97 and it has 198000![]()
