What do I have to do to switch to R134 ?

I've had 134 in the 1086 for some time now and it still cools OK but not quite as well as R12. How well it cools depends on who's sitting in the cab. My son cranks the air all the way up and still tell me it's too warm. I barely have it on and I'm comfortable. Something that helps is to take the lid off the roof and blow out the evaporator. Mine was so plugged I had to soak it with soapy water and then rinse it out. It helped a lot. Jim

you can get the conversion kits from napa. you need to evac the system, we generally hold a vacuum on it with our charging station for 6 hours or so. you need to use the esther oil for the 134 conversion. you also ned to know the r-12 capacity of the system.r-134 is 80% of the r-12 volume. so take your lbs of r12 times .8 will give you how many pounds of 134 to add. i converted my 90 gmc suburban, cools just as good with 134 as it did with r12.
