Hello,
I have 03 GrandPrix it runs great, I have noticed in the last 2 weeks it gets over heating almost to H sign, But it's only while in traffic, but on highways it stays around 210, I check the coolant there is no leak, and there is no oil in the coolant, or coolant in the oil, and I have checked the fans, they are working fine I guess.
Any idea what is it causing to gets overheating?
Thanks alot
