- There is only one drop-in Freon replacement that I'm aware of and
- that's the GHG-12 replacement that I've been working with George Goble
- ghg@ecn.purdue.edu, on. It has not yet been blessed by GMC so the
- dealer would likely not be using it. Besides it increases the cooling
- capacity of the system 20-30%, depending on the particular system.
-
- There is a substitute from Dupont called SUVA MP-52. It requires a different
- kind of oil and is not a drop-in. Installation requires a complete flush
- of the system and the replacement of at least the dryer. Cooling capacity
- is unknown.
-
- The R-134a replacement is a major undertaking. Just about everything except
- the evaporator must be changed. Industry estimates at conversion costs
- range from $800-$1200 for a passenger car. Neither R-134a nor SUVA may
- be just plopped in an existing system. Corrosive destruction and/or
- almost immediate oil failure will be the result.
-
- Your friend needs to find out what was put in his system pronto.
