A/C Compressor

Hey all, I have to replace my A/C compressor and dryer and i was wondering if anyone else has done this and how big of a job it would be. Its an 02 with the 3.4. Thanks

 

not hard at all. 4 bolts on the compressor. 10mm bolts for the ac lines. buckle clamp on the dryer. this might be a little tricky to get to since its so close to the grill. dont forget to evac/recharge sys.

 

Yeah, you will want to evac the system, add oil as required, may want a new dryer... Change it out and take it to a real A/C shop to have it serviced and checked for leaks. Then take it back a few days later if you suspect a leak.

 

Or you could stuff it with lube and turn it into an 'on board' compressor!!!

 

Do not forget to buy and install new o rings when you open the lines..

 

Good Point!!!

 

Thanks for all the help guys. I may tackle this the first of next week. No need to evac the system cause the compressor was leaking and thats why I have to change it out. I read somewhere to lube the new o-rings with compressor oil, do I have to do this or can I use any oil or does it even have to be done? Anyone ever charge there own system instead of taking it to a A/C shop? One last quick question, How hard is it to loosen the power steering belt, I want to change the compressor belt and its behind the power steering. Thanks again, I'll let everyone know how it turns out once I get to it.

 

Be mindful that if your systems been up to atmosphere then more than likely you've got water vapor mixed with air in your whole system. It's generally recommended that you do a couple of "pump-downs" using dry N2 or CO2 to absorb the water rather than waste your R-134. After your final pump-down add the R-134. Add the 134 slowly to the suction side (fat tube going to your evaporator at the firewall. You're completed when your low-side pressure is at aprox. 25 PSI when compressor cycles on and no more bubbles in the drier sight glass. As for an AC shop, well I'd rather pay a couple hundred bucks once for the vac pump, manifold gauges, and sniffer and have the tools for life rather than keep paying a shop over and over again. But then that's me. Good luck.

 

Well a little later than I figured but its finally done! I now have ice cold air! The compressor wasn't too hard to get unbolted, but I had to unbolt the power steering pump to be able to lift the compressor past it. And the new drier was pretty easy once I took the grill out which only took a couple minutes. Once all the parts were in I took it to the local A/C shop to get charged and now its good to go! Thanks for all the help!

 

Did the ac shop put the oil in it , if not how do you know how much and where to put it?
