I did mention how to do it before...

An air con shop will have the right tool for it, you can unbolt the compressor, leave it connected, and fit the tool easily enough from underneath.

You don't need the stupid tool like for Sanden compressors so it's all good

This idiot even gives you an easy run through how to

Thats a Denso 10pa, 15c variant, they put them in the w202 mercs, but have different flanges on them. you can get one here if you've got to get another one, just bolt on your pulley etc.

You can also rebuild these easily enough, there's plenty of videos on youtube and seal kits are cheap

If you just want to do the clutch bearing, you can leave all the lines attached and unbolt the compressor from the block, pull the front of the compressor down and do the job with lines still connected...

I want to buy an RVR auto just to get Aldo to do the box! Your experience in these boxes is next to incomparable

Well get him to put some dye in the system after you replace the bearing to check for leaks. I'd check the compressor engages firstly by bypassing the pressure switch, pretty sure you just stick a wire between the two terminals on the plug to the low pressure switch, I'm not 100% on whether these have a high pressure switch as well so just do the test on both if you see two on the lines. Otherwise, get real crude and jump it (compressor) straight to the battery via a switch with engine running

Mine still had gas and worked fine, just get the thing to fire up first. Most air con people will just tell you to get a new fuckin everything because no-one uses their fuckin brain anymore...

Have a crack at getting it running. Take it to someone if you can't get it going yourself to be absolutely sure. If it fires up, go ahead and put a new clutch pulley bearing in there. Then get the bloke to put some dye in the system first gas, go back, check for leaks (UV light). Replace anything that needs to be. Good to go.

If no go, bite the bullet. Compressors are touch and go around 150k you can never be sure if they're any good. But Mitsi had half decent compressors in most of em. Good luck with it mate

If it's air con compressors bearing, the air con compressors idler bearing was shagged in mine when I had it. it made a noise really similar to the motor pinging when I would hit WOT. Eventually I could hear it at idle and majority of the time driving. An air con shop will have the right tool for it, you can unbolt the compressor, leave it connected, and fit the tool easily enough from underneath. Low gas will just make the pressure switch stop the compressor being turned on. If you have no cold air and can still turn the air con on (compressor engages) you will need a new switch.

I also changed the bearing on the air con belt idler and the alternator bearing. Idler bearing was shagged, alternator was getting bad. Engine had 140K.
