What is the correct way of charging the A/C system on a my 89 GT? The A/C has worked pretty good for the last 7 years I have owned it, but it is just barely cool at the vents now. I need to know for sure what port to fill and if I need to rev engine etc. I'm no expert on the subject. |
Unless you converted to r134, your on a r12 system, it can be costly, and you cant buy r12 anymore, they have a "freeze 12" replacement, but you have to be licensed to buy it here in my state anyway.
Also, It is best to let a vaccuum pump sit on the lines, and evacuate the system, you will get ice cold a/c if you do it this way.
I recommend you convert to r134, it's not too hard, but do some research first, or you can ruin you compressor.
