Maintenance/Repairs

I own a 1991 Toyota Corolla with 79,400 miles. The A/C is low so I know this car use R-12 Freon. The problem is that I know R-12 is no longer so can I fill it with R134a? Is there any DIY to do it? Or has to be done professionally shop?

Thanks

Pete

Certain things have to be replaced, but it isn’t terribly expensive. Have a pro do it for you if you don’t know what you’re doing. A properly done A/C job is always $ well spent.

You can still find R-12 from people who deal in old car parts, but it’s expensive. However, it still may be cheaper than converting to R-134a.

If the leak is fixed.

Google “Freeze-12”…Pro’s HATE it but backyard guys love it…

WalMart sells an R134a kit that says “compatible with R-12 residue”. When it leaks out eventually, look for a can (at WalMart again) that says it’s compatible with R-12, stops leaks and conditions the compressor seals.
