Try adding a half a can of Freeze 12 to your system, if you have access to the fittings necessary to connect up to a can of Freeze 12 and a recovery system to remove some of the Freon 134A. Freeze 12 will drop the condenser pressure and vent temperatures quite a bit while maintaining the 25 to 40 psig suction pressure recommended for R-134 systems.


It's compatible with 134?

I did the fan clutch oil swap tonight, at least, after draining for 24 hrs I refilled and reinstalled the unit. Works worse than before. I actually measured what came out and put in the same amount so I don't think I over or under filled. It's cooler here right now, though, I'd say high 70s, but even so I would expect the clutch to kick in at some point. Nothing. It sounds as if I don't have a fan at all, even after running hard on the highway. AC is doing the same thing it was before. I'm not sure what's going on. Next step is to lower the system pressure and go back to an OE fan clutch and hope I can get it to behave better.

My thinking is that the AC on the Trooper just sucked stock and it sucks even worse when R134 and I'm stuck with it. Guess it's time to try and sell the truck again.
