Is it pretty easy to change comp.....it is leaking at front seal.Do you need to replace accumulator also? Need to convert to R134?

 

Most likely you will need to replace the accumulator/drier if the system is opened. There may be shut off valves to isolate the accumulator. If there is you are in luck. Don't know if that seal can be replaced in car but that is the way to go, if possible. The important part, after removing a comp. is the evacuating and recharging the system. Do you have a vacuum pump to do that? Moisture and air are the killers of A/C systems. If you can't do it get an expert that ONLY does AC systems. If the AC was working well before you may be better off changing the seal in that rather than buy OPJ.
