I gathered the information directly from the Pontiac service manuals. I agree that depending upon the timing of publication, some of the codes may have changed, but were authored by GM and considered accurate at the time of printing.
I agree that service manuals tend to be much more accurate than the parts manuals, but they can have errors. Someone had posted the other 69 radiator codes on a forum. Not sure what their source was, but a couple of the codes were different. None of the Camaro service manuals have radiator tables like that. Y'all are lucky.

Kurt, reading your page, the diameter of the four blade fans used on Ram Air Firebird and 396 Camaro is larger than the diameter of the four blade fan used on the L6.
Really? I've never seen a different size fan. I'll have to ask around. My 396 car had a clutch fan, so no help...
PMI, I didn't realize some trans were aircooled! Thanks!
