My 84z has a.c., going to retro it to 134a is the lowside fill the line up topside in the engine compartment or the one closer to the bottom by the frame/pass. side? Thanks. How much should it hold, 1 can oil and 2 of freon, Im not sure with this old of a car, if it was newer no problem.

 

I just did the one on my 92, I would think a 84 would be the same, the low side was located on my accumulator and if you buy the conversion fittings they only fit one way. I added one 8 oz. can of ester oil and 2-12 oz. cans of 134a and it cools just fine.

 

Thanks for the info on the a.c., if anyone else has any input, I'd appreciate it.

 

fittings fit one way...retrofit kit worked great on my formie
