freon in 1991 sc400 motor

[zdatsupra]

hi all,
can someone identify the freon thats in a stock 1991 sc400 motor? is it R12

I got out of the supras but have not found a good forum like this for the sc.

should be r134a.

It will also say on the hood.

thanks, i actually found the sticker today i had not seen and its R12.
it looks like its leaking from the top manifold on the compressor just like the mkiii are famous for.
anyone have an excerpt of the manual related to the 1uz-fe motor and ac?
need to know the volume of refrigerant and recommended pressures...

when i replaced this manifold gasket on my supra, i did the evaporator and expan valve at the same time.. then later on, my compressor seals went bad. may just do it all at once this time.

Any shop that does a/c can look it up for you. Are you just using a/c in a can or something?

It should be R12. R134a wasn't mandated until 1996...

I thought i was earlier than that.

Was that all cars in 96 with some already having them?

Manufacture of 12 was banned in 1994 (Montreal Protocol) so I suppose you could find 134 around then. I've never seen it in a Toyota that early though and especially not in a 91. Your advice to check the sticker was spot on however...

...may just do it all at once this time...

A very wise approach when dealing with MVAC...
