a/c

[Blazer Eagle]

so i know this has been discussed before but i couldn't find the threads

what i have is a 1974 blazer with no air conditioning, on another site i pondered how easy it would be to take the a/c parts out of a truck and put them into my blazer, it all semmed pretty simple, a lot of little screws for the ducts, the evaporator the condesnser and the compressor

but what somebody brought up is that the old chevy system runs on r12 coolant which is really expensive now that the new cars run on r13a

what are your thoughts on the matter?

Get an aftermarket system with a Sanden Compressor, it will work mo bettr
and will be more dependable.

You can complete a R134a conversion on the old R12 system. Although it doesn't work as good as the old R12 it will still perform well. The conversion is pretty simple, require some oil in the line for the compressor, but nothing else really special. The 134a is way cheaper. Its a fairly popular thing that most AC repair type people should be able to handle easily.

I am in the process of doing the same thing and was going to go 134, but then my neighbor was moving and came up to me with a cylinder and said it was R12 that he didn't want any more, had all new cars now. So I basically got about 12 lbs of R12 for nothing. woohoo for me.

Good luck your project
