Retro Fit, R-12 To R-134a

Alphaman on Tue June 02, 2009 2:57 PM User is offline

Year: 1994
Make: Oldsmobile
Model: Bravada
Engine Size: 4.3 W
Refrigerant Type: R-12
Country of Origin: United States

I want to change the R-12 to R-134a. Accumulator must be replaced, What kind of oil should I use?
PAG oil or Ester oil? Should the ofrice tube be replaced?
The hoses must replaced, I don't think they leak R-12, but with R-134a, I need barrier hoses?
How about the Cycyling clutch switch?
Thanks Mr. AlphaMan..... the great......

R12 is the best solution for the repair of that vehicle.

Hi Alphaman; Please listen to bohica, leave it R-12! Most here will say the same. Too many have spent big bucks to convert and were very disappointed-- Higher costs,(compared to just recharging with r-12) higher vent temps, lousy performance all around, etc! I have a feeling someone might have suggested to you to convert, to "save" money, r-134 being less expensive-- You will not. Just read some of the threads here of folks converting--very few success stories, LOTS of bad stories. Hope we've convinced you

Double check under hood label, the 1994 Bravada "should be" R134a already...
