A/C Compressor Change out
Any tips on Changing the A/C compressor? On a scale of 1-10 how aggravating is it? If you've changed an A/C compressor, which compressor did you swap the old one with? Should I do anything else besides changing the belt while I'm at it?
Thank you!

Re: A/C Compressor Change out
I used an ACDelco compressor. About a 6 in aggravating due to tight access and having to work mostly from the bottom. What you have to replace will vary depending on why you are replacing the compressor. The accumulator should be replaced anytime you replace the compressor. Orings for any joints you disconnect or that are leaking. Oil. The amount will depend on what you replace and if you flush the system. I think 8 oz of PAG150 is the total system capacity.
If you find any black gunk or metal shavings when you open the system you will need to do more. You will need to flush all the lines and evaporator. You would also need to replace the condenser and expansion valve.
The compressor manufacturer will probably have a list of parts you have to replace to be covered by their warranty.
