The A/C compressor on my 97 OB 2.5 is bad and I got another from the wreckers. Anyone know how much refrigerant oil should be added to it? Do I need to purge the part first?

Hello RodA and welcome! Posted Image

From the factory service manual:
If the compressor is replaced (after stabilization):
Drain and measure the oil from the original compressor.
Drain the oil from the replacement compressor and refill with the same amount that was drained from the original [20 ml (0.7 US fl oz, 0.7 Imp fl oz) minimum]. Always use ZXL100PG for the replacement oil. (You might want to verify your system's specified oil; I can look it up for you if needed).

Thanks, I'll try that. I think all the oil drained out of the second hand one, but I can try measuring the amount of the one in the car.

now, i say this to make a point, so read all of it. not that i recommend it or that it's a good idea, but typically there's enough oil in the system to probably get distributed through your used compressor without adding anything. now, again i don't recommend it and that's not what you're going to do since you also risk completely trashing your system. but my point is, don't feel like you have to measure the quantity to some very specific accuracy, because that isn't the case either. make a good judgement call after hearing some knowledgeable suggestions and enjoy the cool air!
