My Trans am has a problem with heating up. at idle, it just keeps going up and up and up...scary fast. I pulled into a parkway rest stop over the summer to put my t-tops back on quick, and when i got back in the car, my car was at over 260, and the coolant was boiling out of the tank. Anyway, I found that when the car is getting hot, turning the heat on full blast helps take away some of the heat, but what I found interesting is that when the AC is on, as long as the car isnt already running hot, the AC helps keep the car from heating up. I was stuck in traffic trying to get to jersey gardens the week of the Republican Convention (bumper to bumper going nowhere) and I was freaking out thinking my car was going to get too hot, but the ac really kept it down. it did rise, but only by maybe 20 degrees over the course of probably sitting in traffic for an hour. Can anyone offer an explination as to why the AC helps keep the engine cool? Thanks.
