1993 Dodge Ram R12 R134a conversion
So I am in a middle of a dilemma.
I have to replace the blower for my 1993 Dodge B250. To do so, I have to remove the AC system above it. Thus, I have to discharge the R12 and evenutally refill with r12.
This charge to refill the R12 is $375 in CA where R12 is $30 a pound; plus replace rates.
Now I am thinking about converting to R134a. My understanding that I will need to:
- empty R12
- flush system to remove existing oil
- replace drier
- replace fittings to R134a
- replace R12 label to R134a
Do I need barrier hoses?, replace O-rings? new compressor? Neoprene seals?
I am expecting "It depends" answers, if any.
Anyone done this on a Dodge Van?
