I do not know for your rig.

The details were listed on my coolant surge tank as I recall and specified 134a. Perhaps yours is there also.

You should be able to tell by the type of fittings on the A/C fill. R-12 and R-134 have different fittings to make it more difficult to fill with wrong freon. Use Google to find environmentally safe R-12 substitutes if that's what your set up needs. It is cheaper and legal to buy. Test pressures before installing, it is common for A/C to be full but doesn't cool because coolant is still flowing into the heater core and the flap that allows outside air is still open. Try A/C on MAX COOL and see if it is cooling better.

Automotive Air Conditioning Systems That Will Not Accept Freon | eHow.com

Here is a brief summary of causes of AC system not allowing 134a into the system.

There is a lot of specific advice on the web. That is how I learned to locate and replace my AC compressor last summer.

Note: If you have the Over-The-Road bus air feature providing AC in the bedroom from the engine compressor, there are two driers in the system that need to be replaced when the system is opened to the atmosphere.

One next to the engine and one in the cabinetry above the bed.
