R-134a, there should be a sticker under the hood.
The only stickers i saw were a couple and all say R-12 But the high pressure valve is big as the ones with R-134 That`s why i`m confused
than that means it may have been retrofitted, there should be another sticker someplace that showes that also, unless it was done by a "backyard" mechanic
Nope,no sticker with R-134a anywhere,but i`m going to go with the R-134a the hi side valve won`t fit the R-12 recharging hose.
92 would be R-12 from the factory.
The S P/U used R-12 till 93 , The S Blazers had R-12 till 94.
Thanks i was going nuts trying to sort it out.
