Does anyone know what kind of refrigerant is used for the A/C unit? Also, I see those little bottles in the truckstops for do it yourself. Is that the right stuff to put in and do they work?

If you are getting some cool air I have used those type,but buy them at WalMart as they are much cheaper there,it lasted the whole year after I recharged mine with one.

Ya, but what type of refrigerant. They many a few different types. I'm not sure what type my 2001 truck takes? Maybe I'll wait until I get to Texas and have someone do it. I don't think you can mix different types.

dont worry.. if you buy the wrong one. it wont hook up. it should be 134-a
i buy from walmart. very easy. but buy a gauge also so as not to overfill sys.

Ok, thanks for the replies. Maybe I'll give one of those little bottles a try. My compressor kicks on for about 30 seconds then off and continues this cycle. I think this is due to not enough gas in the lines. I have an A/C temp gauge that a HVAC person uses and my output is about 65 degrees and it should be a lot colder than that.

I had a BMW before that didn't get cold enough. My buddy had me rev my engine up then pumped a ton of freon into the system. Ice started forming at the vents for the first week after that!

mine blows at 41 degrees after 1 can.

I called my A/C friend and he had me stop at Walmart and buy a little kit with a guage. I put the gauge on and it was below normal but still plenty of pressure so that ruled out a massive leak. I put 4 cans in and it raised the pressure to just at the OK mark but needs to go more. He said it would take 20 cans to get it up since it's a big unit with lots of pipe and would be cheaper to pay a garage $29.95 to dump a lot in.

It went from 65 to degress to 50 so a huge improvement and it's nice and cool in the truck. I'm still going to get it charged the whole way when I can.

Nice here in Texas, in the 70's
