Good question! I hope someone has the answer to it because I am kind of curious myself. I have to recharge mine before the heat comes in.

You set the proper pressure on the tank and then you fill through either the high or low line....dont remember which though.

Originally it was probably R12. If it has been converted to r134a there should be a tag under the hood specifiying that. If not, take it to a garage and have them vacuum all the r12 out (If there's any r12 in the system and you add r134a, I've heard you can seize the compressor and that costs $). Then you can just go to an autoparts place and get a conversion kit. They're usually like $25. It will come with the adapters you need to hook the r134a hose up to the r12 fitting. Then you just put the hose on the can, shake it up, flip it upside down and hook it to the low pressure fitting on the a/c line. (If you bought an r12 -> r134a kit it probably comes with some oils and all the fittings you might need as well as the instructions). Just make sure to keep an eye on the gauge that's on the hose (probably, some hoses don't have a gauge). As with everything else on your car, you don't want to overfill it. You might also need to get the compressor going, but I can't remember.

never even heard of R12
R134a is where it's at. ^^that guy seems to know his stuff.

It's all about the year of your car.
Older cars came from the factory w/ R12.
Then some legislation got passed that banned R12 from new car sales and mandated that people try to move to a more environmentally friendly refrigerant (R134-a). My memory tells me something about R12 in the atmosphere leads to ozone depletion....

Like Ethix said, if you have an early car (mine's a 93) you should have a sticker on the underside of your hood, near the front of the car, which says you've been converted to R134a. My sticker is dark green.

Hope that helps,

Quick question. I have a 92 which came stock with r12. I have a r134a compressor and would like to convert my system over to r134a. I was always under the assumption that more than just the compressor is needed to be convert. Does anyone know the list of parts needed to correctly convert to r134a. Thanks in advance guys.

My understanding is that you just have to remove all R12 from system, change o-rings, stick R134a nipples over the R12 nipples, and refill system w/ R134a.

I've certainly seen kits at Autozone/Pep Boys/Advance Auto that only contain those items and claim that they can convert your A/C system....

Does anyone have personal experience w/ this?

Ethix

I've never done it myself, but my friend converted his and he did everything you mentioned except changing the o-rings. He converted it last summer and it still works awesome.

Next time im at autozone, i'll check out the conversion kit and see whats involved. Hopefully its just its pretty simple and doesnt involve changing any of the lines or condensor.

Local toyota dealer converted my 93 to R134a for only $100. Now when it leaks - no, i didn't feel like gettting the pressure line replaced - I just add a can of the recharge stuff from autozone.

no problems, no need for a different compressor or anything like that.

The '92 came w/ R-12.

basic retrofit to R-134A is to change the fittings & add 2-3oz of "retrofit" oil. This is for a
basic change over, if repairs were made extra oil will be needed to make up the loss.

recharge the system to 80% R-134a to what the hood label says.
EG: if the label says max charge 1lb then you add 12.8 oz of R-134a.

NOTE: if your buying 1LB cans @ pep boys/ autozone MAKE SURE your
buying R-134a. NOT freezone or other junk. IT IS NOT THE SAME as the
sales guy or your friends say. R-134a is only a few $ LB more, trust me
& spend the extra.
