if anyone could help that would be beyond awesome... i have a 2000 silverado 1500 with a 4.3 v6 and just recently my ac compressor seized up so i went to advanced auto and ordered a new compressor. (link below)... now what im trying to find is what to torque the bolts to and also what pag oil do i need ... the table given with the compressor looks like this table (http://www.discountacparts.com/image...ressor-oil.jpg)

and i dont know which model my compressor is so any help would be greatly appreciated

Someone correct me if I 'm wrong, but I think the torque for the compressor bolts is
37 lb ft and the oil is Pac 150. The new compressor should come with oil. The whole
a/c system should hold 8 fl oz. I take it, since the compressor went out on you, the
system isn't pressurized. Once you replace the compressor you have to evacuate
the system to remove any air and moisture, then recharge the system with R-134A
refridgerent. Check the top of the accumulator to see how many lbs to install.
Only charge the a/c system on the low side service port with the motor running and
the a/c controls on cold and the blower on high.

The oil is PAG 150.
You will definately have to pull a vac on it to get the moisture out of the system before you charge it, so be aware of that.

well, what you should have done, was take that compressor out, put it into vise, pour some good oil inside, and hand crank it. we de-seized compressors like this before, to our ultimate surprise. actually, was quite easy. have no idea how bad they where seized comparing to yours, but would guess - about same.
good chance is, you fried your a/c clutch same time.
