Does anyone know what the part #'s are to replace the o-rings on the accumulator and on the high pressure side where the orifice tube is at? Also do the hoses in back of the compressor have o rings? Going to replace all those things to before i recharge the system with R-134. Thanks!

 

No part #s, really...

Just go to the parts store and buy one of those huge assortments of the green ones.

There are several styles that could be on the compressor; no way to know which for sure, until you take the lines off and look.

When you replace the compressor, as really needs to be done because the oil in it now is incompatible with R-134A and will turn to some kind of gel, it will come with whatever seals the particular compressor needs.

Use the "red" or "orange" Frod orifice tube... have the parts store look it up for about a 98 Crown Vic or something. Happens to be a better match for R-134A in a GM R-12 system, than any of the GM ones for either R-134A or R-12 systems.
