I took a little time to look at the truck today. Just for my own curiosity:
I removed the two caps from both ports and depressed one of the schrader valves and got absolutely nothing.
I pulled a vacuum for 45 minutes. It went to just below 30 in a matter of one minute. What does that tell you ...

He was going to use this in his 2004 but he sold that truck so he still got the stuff. It’s all brand new.

My brother-in-law will sell me a complete kit for $350. That sounds pretty good to me.

I was going to work on it a little today, but the air quality here is not very good and I’m doing the work outside.
Just out of curiosity, I think I’m going to put my gauge on it just to see where it’s at right now

My initial plan was to replace the complete ac system because of the age. I have a brother in law that can get all the parts at a super price. My only problem is the evaporator. That will be a real pita to replace.

I would flush it but I don’t know if my compressor is big enough to accomplish that

It has 160,000 on the clock.

Two, if you want to chance it and chalk-up the refrigerant loss to annual seasonal losses from the compressor shaft seal, recover the refrigerant (or have it done), replace the accumulator and OT, evacuate, and as above, recharge the system to the manufacturer's specifications (by weight, of course ...

I have done a little ac work before so I am not a complete newbie but I am wanting info on where to start this project. I have had this truck for 10 years and very seldom drive it but I want to get the ac working. As of now, the ac is not working. The compressor does not engage. What is the first ...

OK...just want to give an update. I have been doing diagnostics with the help of a "corvette mechanic and friend". With his help, we found the Blower Control Module to be defective. Compressor is now running. I turned the compressor off and on a dozen times to burnish the hub and pulley face of the ...

hi
Always start with 90% going from R12 to R134a then charge according to
pressures high /low expected for the system
low around avg 28psi
high side no more than 250psi but lower below 200 is ideal . If high side is around the 250 psi really needs more condenser and or fan
txv system ...
