AC Compressor replacement - What other parts are needed, if any?

I am getting ready to replace the AC compressor on my 03 GT and I am trying to determine what other parts (if any) I should replace at the same time. I've read about replacing the drier, but it's built into the condenser and I wasn't really planning on spending another $100 on a new condenser.

belt is new, lines are fine from a cosmetic standpoint. Will be purchasing compressor oil and freon, but was just wondering about what the risk is of other system parts having been negatively impacted by the compressor failure.

Define failure? Did it explode? If so fragments of parts could clog up the lines and so forth. Causing cooling issues.

The drier is inside the condenser yes but you can still replace it without having to replace the condenser. It look like a large nut on the tube part of the condenser on the drivers side. Open up the large nut. I think it was a 22 or 24mm and it is a dececant sp? bag like thing in there. They are cheap and if your compressor let go internally then I am sure it is full of crap and needs to be replaced.

The compressor did pretty much 'explode'. It was knocking for a while and then went with a big bang. I checked it out and it's got a nice fat crack down the side of the body. I'm thinking at this point I will open the lines and blow them out with some compressed air. Depending on what comes out, I'll try to decide whether lots of pieces got into the lines.

Driers are cheap. Do it right the first time so you don't have to do it again when it will cost you more. Plus your a/c will work better. The drier is like the filter of the a/c system. The first time is always bad enough. Going back to do something a second times sucks.

so where would I get a new drier? I didn't see it available separately from the condenser (at least at Autozone). Ideas?

Nevermind, I see now. I was thinking the drier was on the side of the condenser. This is what I found on the Autozone site and I'll definitely replace it..

Everco/A/C Receiver Drier (83124) | 2003 Mitsubishi Eclipse 6 Cylinders H 3.0L SFI | AutoZone.com
I used 03 GTS cuz that is what I have. It was under reciever/drier #83124

It is just a bag $15.99. The screw that comes out looks like the shiny metal thing on the far left of that pic. Comes with new o-ring and whole nine yards. There will be a ton of black nasty crap in your old one when you pull it out. I removed my condenser and flushed it with some stuff made especially for flushing a/c systems and got a ton of crud out.

Thanks for the advice. I think I will flush the condenser also, since it's directly downstream of the compressor.

This is taken from the maintenance section. You may be particularly interested in the highlighted info:

Quote:
Before opening up the A/C system, take the vehicle to a garage and have them evacuate the system of all refrigerant. DO NOT vent the refrigerant in to the atmosphere. R-134a does not damage the Ozone layer like R-12 does, but R-134a is about 100 times more potent of a greenhouse gas than Carbon Dioxide.

Once the system has been evacuated, remove the output hose from the compressor, It is the smaller one. Look inside of it. If metal shavings or flakes can be seen stuck to the walls of the tubing, a replacement Compressor and Condenser Core will be needed. The Receiver/Drier is built in to the Condenser Core and cannot be replaced separately. Do not skimp on the Condenser Core. Failure to replace it after a catastrophic Compressor failure will only destroy the new Compressor. It is also recommended to replace the Expansion Valve, since it may be clogged with debris as well.

If any parts are replaced, be sure to add compressor oil to the new part. Mitsubishi calls for PAG 56, but it is not available except from the dealer, the closest grade is PAG 46. A Compressor holds 100 mL, although sometimes it comes pre-filled, check anyways. A Condenser Core holds about 15 mL of oil.

I did see a lot of dirty crap inside the line coming out of the compressor and flushed it. I also replaced the guts of the drier and flushed out the condenser with some ac flushy stuff. The new (used, bought on eBay for $85) compressor is doing well, except that I still have a leak in the system somewhere. So now I get to bust out my UV lamp and go leak hunting.

Is process same for 2001 GS?

My compressor starting making a horrible rattling sound. I removed the belts and confirmed the culprit was the compressor. Now I am searching the forums to determine if this is a job I can do myself. I appreciate the information in this thread, just curious if there are any additional steps or otherwise to replace the compressor on a 2001 GS?

Currently the car is in my garage with the belt off. It's drivable, but without power steering. I'm tempted to replace the compressor myself just want to confirm all the parts I will need.

Can someone confirm that you can replace the drier on a 01 GS without replacing the entire condensor?

Also, if I replace the parts myself, will an AC shop having any issues vacuuming and/or recharging the system if I bring the car to them?

Thanks

I have a brand-new GT compressor for sale in the marketplace if you need one.
