O/T Evacuate Air Condition Lines.

I'm putting the Caravan back together after the deer altercation.

The condenser is so twisted that I can not bang it back in shape and have any confidence it will not leak. I bought one at a wrecking yard for $12. It comes off with one nut which connects the condenser to the AC hoses. The wrecking yard, of course has evacuated the system and drained the R12.

So, I've a question... How do I evacuate the pressure lines so that: <ul type="square">[*]R12 is not sprayed all over the place,[*]I can recover the R12 and not destroy the 0zone layer?[/list]Of course, any hints on drawing down and and recharging the system would be helpful.

Re: O/T Evacuate Air Condition Lines.

its not as difficult as you would think.

use this to draw a vacuum:

use one of these for servicing:

its pretty straight forward to do a/c work. my pops invested a little more into his equipment to work on his cherokee's a/c. the condenser had a crack at a coil elbow, but after having the right tools for the job, it was a piece o cake.

Re: O/T Evacuate Air Condition Lines.

Both the guages and the pump will only work with R134, I'm trying to not refit to take the R134, and refill using R12... if I can find the stuff.

It cost me about $100 for the R134 retrofit kit and dryer for our Cherokee....
I would speculate that the R12 will cost you a lot more than that....I hear it's going for about $1000/jug for R12

Re: O/T Evacuate Air Condition Lines.

I can't see it being economical to buy the needed equip to do one car yourself.

Todays retro fit kits have the new oil additive in the 134a, cross contamination with residual r12 and it's oil is not a problem. I recently did my Cherokee with a $40 kit from Advance Auto and it works great. I had no r12 left to recover.

As far as recovering the r12, I'd take it to a shop and let them have it no charge. At $50 a lb you might make a deal, get them to evacuate it twice. Once to get rid of he r12 and again after you install the new parts.
