it works but theres a reason why it all leaked out its a closed system in a week you will probaly add another can and
There's a lot of unknowns with this truck. It sat unused for a long period of time so I'll see how long the charge last. I have guages, sealant, and more freon. <img src="/forums/images/graemlins/smile.gif" alt="" />
One issue I did notice today was that the idle was way high (2k rpm) with the A/C on. Is that controlled by the Fast Idle screw?
IIRC you can control the AC idle up on the carb, it should be the passanger side of the motor, a little diaphragm with a vacuum like attached.
As far as the A/C goes here's the story: R-134a (what you have) is alot different from R-12 (stock) when you convert you must change out ALL the o-rings to ones that are compatable with R-134a, as it will eat the R-12 o-rings. Also in talking to my neighbor who's a car A/C guy(and a really good one at that) he tells me that R-134a is physically smaller in size than R-12 is, this causes problems in systems that weren't designed to use the newer R-134a. In new cars what have the R-134a from the factory they use what's called "barrier" hoses which instead of being straight rubber, they have IIRC a nylon 'barrier' inside of them that keeps the smaller particles of the R-134a where they are supposed to be. Now the best way to convert is of course to change all the o-rings about 10-12 and then change the hoses. Me, I'm in the process of buying the o-rings I need from the stealer (R-12 compatable) and then I'm gonna recharge with either R-12 or Freeze-12.
