I have a 99 GT and I had the coolant changed about a month ago. But recently the coolant light comes on when I get on it. But the car is not running any hotter than before. I've checked the level and it is fine. I did have to top it off when they changed it because the shop I took it to did'nt. I'm thinking that there is an air pocket in the system, if that's possible. The light does go off after the car is turned off. But comes back on after it runs for a while. Any and all help is appreciated. Thanks.
