DIY automotive AC recharge?

[Moody Blue]

Have a 96 Safari van and the AC stopped working last year. The summer before that I spent $600 getting it fixed and don't feel like spending that much again on an old vehicle that I will probably sell next year.

There is still some pressure in the system and when I bypass the low psressure switch the compressor kicks in as it should. I was thinking about getting some of those aftermarket recharge kits, only the genuine R134a not the other stuff on the market. Is this something I can expect reasonable success with? What about having it shipped across the border into Canada, any issues?

Your system should be a R134A and to recharge it is easy...just get the kit. The true question is where did the old stuff go? You obviously have a leak regardless of how small. Recharging it means it will work fine and get worse daily due to the leak.

Bofore you fill it check ALL your fitting and make sure they are tight.

R134a is molecularly larger than R12 refrigerant, so it won't leak as easily as R12

Go to AutoZone (or other auto parts retailer, even Walmart has them), and you'll find a kit with a gauge and hose for $25 or so... get the large light blue can of material that has stop leak, leak finder, oil, and refrigerant, .... follow the instructions and Good Luck !

The leak finder is a dye in the refrigerant... it will help identify leak spots if any exist.

A company called Clip Light makes a great stop leak. They have it just for automotive as well as other small to commercial units. I've used the stuff several times with success!

I had several units that had leaks in areas that did not have access to repair. Their product stopped it finally. Saved the company $3000 for the hopper and barrel assemby replacement. The stuff is not cheap, but not real expensive either.

Only problem or drawback is if the freon lines are open to the air, the stuff will start to harden/gum up. Just immediately cap the lines and everything will be okay.

No probem charging it yourself, just don't overcharge the system.
