car overheats when the engine is driving at high rpms

as in up hill, when the rpms are high the temp goes up, but the problem is that i when i drive at high rpms on a level surface i don't get the same problem. i feel that its just lack of air when i am driving up hill, because if i drive down hill in the same heat and even at high rpms the car runs fine no major temp change.

any tips for me?

Re: car overheats when the engine is driving at high rpms

do you still have the lower air dam that attaches to the bottom of the radiator core support?

Besides the air dam, Camaros (at least some) have a Baffle, Rad Air Lwr GM p/n 14107379. Check the following link, post #13.

This is common, my car does the same. Think about it higher revs=more heat. Its how an engine works. Then add in the extra load from the hill and it all makes sense. Our cars are built to overheat.
