Answer
Hi Justin:

when the car overheats does the electric cooling fan run on the radaitor? If not then you have to find the root cause of the fan problem. If the a/c on this car still works turn it on and after about a minute the fan should come on if not then ther for sure is an issue with the cooling fan. If the fan runs and it still over heats I'd start looking for an engine mechanical issue like low on coolant or a head gasket problem. Possably a restriction in the air flow across the radaitor??? just a few things to look at. Good luck :)
