Does anyone know what kind of refrigerant goes into Corrolla '93

R12 most likely. Look under the hood. There should be a label somewhere telling you how much it holds and which refrigerant it uses.
 
According to Edmunds '94 was the first year to have R-134 refrigerant.
As nutbucket said there should be a sticker under the hood somewhere that says what type and how much refrigerant it uses.

Ummm isn't that just a little illegal?

Yep. My guess its probably relabled cans of R134. I've heard of this scam when ppl goto Mexico to get R12.

EDIT: There's also stuff called Freeze12 (available only to licensed technitians) but its about $10 a pound and is completely compatible with R12.
 
i'll keep this in mind. my car has a leak somewhere. i originally thought that i would have to fix out something expensive, but since i'm going to trade the car in a few years, i figure recharging it every once in a while would be worth it. (especially after i found how easy it is to do).

If it's 93 it's most likely R12. You can fill it with R134a but it won't cool as well.

If you do it, you'll fry the compressor. You have to retrofit the system properly first.

My camry is a '93 and uses R12. You can buy a conversion kit..I think it's some new o-rings and something that will let you use R-134a

I'm not a believe of retrofit. The benefit is your next recharge will be cheapter, but if you get the leaks fixed right in the first place, there is no such thing as next recharge unless you crash.

That's bull. It will not "fry" the compressor.

Yes it will. R134a does not carry mineral oil and leads to lubricant starvation, which obvious causes compressor failure. If you retrofit properly with proper lubricant, it is ok, but my response was to "you can just add r134a".

Well, I know plenty of people who evacuate and fill with R134 and the correct lube. Works great.

You just answered yourself. Read what Shawn said carefully. What he said is just charge the system with R-134a as you would R-12.

But the article you linked to says this at the end:

In summary, retrofitting to R-134a refrigerant in most cases can be done very easily and cost effectively. Removing the old mineral oil from the system is not always essential. As long as you add the new PAG or POE oil, proper oil return can be expected. Depending on the level of system performance you or your customers expect, R-134a retrofitting can be accomplished on most vehicles with little if any system changes. Remember, always consult the vehicle manufacturer for any specific guidelines they may have.

Seems to discount your statement. As long as you add the POE or PAG, and I'd honestly replace the receiver/drier to make sure you've got as much old oil out as possible, then the retrofit is typically quite easy. Seems to sure work for lots of people with not a lot of problems.
 
If the valve looks like a large version of a tire valve, it's R-12. If there are no threads and it looks like a quick-coupling, it's R-134a.

Getting the oil out isn't always as easy as you think 😉. All I said is if you simply charge it with 134a, you will kill your compressor.
