4RUNNER 1992 Freon Replacement, good idea?

Hi, my air has now for the first time begun to blow hot. Any feedback about the odds for success with the spending of money to add freon would be greatly appreciated, thanks for your comments, Rick

There is a 99.999% probability that you will be successful in spending money to add freon to your air conditioner.

If you want to spend your money wisely, I recommend that you have the conversion to R134A done instead of looking for someplace to install R-12. You will still be successful in spending money on the repair but it will be less money.

Greatly appreciate the answer, how about throwing in a 5,000 btu air conditioner into the back of my 4x4, adding a 600 watt power inverter and some air ducts?

This solution is not very stylish, but how about an RV air conditioner?

least you don't need an inverter :-)

Really. Back just a few years ago, replacing R-12 was easy. But, since the EPA has put a price on the use of R-12, it is currently cheaper to convert to R-134a. Do this instead. Last check: R-12 (retail to the consumer through a licensed repair facility~ $95/lb!). You CANNOT buy R-12 yourself; you need to be licensed.

Did you ever have the free special service campaign done on your A/C? The will replace the expansion valve (if corrode), seals and recharge with R12 FREE! Even after all these years. check

for SSCP01 JUN 93 Campaign - A/C Expansion Valve If it is not corroded then they add a special anti-corrosion agent --- but more than likely its corroded and has leaked the R12.

Thanks, I certainly will look into this. I'm not the original owner and this is a 1992, are you sure there's no time limits and this applies in Canada? That site you mentioned, do you have to join to get the details? Here's another referance page for Toyota recalls.

There are other choices besides R134a. R134a is not too bad in a new system designed for it because it has a lower heat content and a higher pressure curve the R12 and may or may not work well in older R12 systems. So not only will it likely produce less cooling it will also run a a higher pressure which is more strain on a older compressor plus the big wild card is that R134a is not compatable with R12 oil at all so you have to add oil (in effect overcharge it with oil) so that it can bid to R12 oil and to R134 so it can be properly circulated through the system. R134 is not the best sub for R12 in a system designed for R12 though a lot of people will tend to suggest that it is.
