I agree there are other pontiac owners with cooling issues... but at 75° it should not be overheating at idle or when moving, especially with an aluminum radiator..

Ive read the 1st gen firebirds dont have ideal air flow, do you have the full shroud and fan is positioned right in the shroud? Are there other pieces that go around the core support ive read about?

Ive also heard that electric fans can restrict air flow and cause cooling issues compared to just the stock fan. One member on here has a 700hp gto that said he tried electric fans & other combos of parts but the best was a stock fan & shroud.

Just some suggestions & things to consider, hope you can figure it out.
