I have a Tech II in the shop but don't have a candi module so I can't track temps. If I can use a friends candi module I will track the temps and see what happens. If I really get ambitious I will hook up the data logger.........we'll see.

Excellent cooling system chat by the way, thanks.

Ken,

How about R12, and a GM swash plate 6 cylinder non-cycling compressor? Comfy!

109F, idling, and gauge at 3/4 doesn't sound too bad. Which direction was the nose pointed relative to the wind? It would be interesting to pin down the conditions where these things are getting hot. I was at the Hummer Happening near Los Angeles in the Santa Monica Mountains, and temps were low 90's. I was watching the guage closely, because of the overheating reports. One minute the guage was just below the red zone, and the next it was mid-point, even when just idling with the air on. Seems like something isn't quite right.
