2000 S70 - Question about A/C compressor shim fix

[cn90]

falconbrother,

If you want a permanent fix, it is actually not that hard as long as you have the right tools.
You need to make a home-made puller (or modify the universal AC Clutch tool), and use M5 bolts to extract the AC Clutch as it is stuck to the compressor shaft.

1. The AC Compressor is held by four (4) 14-mm bolts.
The two (2) inner bolts facing the engine: they are bolted into an aluminum bracket (you can see it from below).
So once you remove these 2 bolts, the bracket will fall off.
During install, just apply a bit of RTV on the back side of the bracket to prevent it from falling off.
The bracket can only be fitted in 1 way.

2. Once you angle the AC Compressor down, it is much much easier.

I posted info here (Clutch gap adjustment with Compressor in place):

More here, note that below is for V50/S40 but the idea is the same:

Plastic did not work for me so I ended up using wire (bare, solid). Found just the right gage and just worked it around the 3 guide pins after prying open a gap. Just snake it around and then twist the two ends to keep it in place. No problems after a year. Can always add thicker wire when needed.

Thanks guys - using the bread tags - 10 min fix. Tested for about 40 miles in 100 deg temps today. Another cheap (but effective) fix from the forum.

Great forum!

The bread bag ties will probably last the summer if your not in a real hot location. I did that and they melted over the warm season. The hose clap sections are still kicking.

Another happy new forum member here, did this shim fix this morning and has fixed my issue, saved me $$$. My 2000 s70 air con would work for 5-10 min then start blowing warm air. If the air was turned off for 5min then it work work again as above. I did not measure the gap with a feeler gauge and just took a punt after much reading on the issue. I just used a few beer can clips cut to size as below, nice and easy.

I use some long nose pliers to get the clip started after levering the clutch down with a screwdriver, then just pushed it all the way in with the other screwdriver, also dropped a little super glue on top of each but this probably didn't need to be done.

Absolutely Awesome!!! Thank you all!

So what seems to be the shim of choice?

Zip Ties?

Bread Clips?

Metal?

Whatever leftover material you find around the garage will work. When it was time to do mine, I found an old brass nameplate (about 1/2 mm thick), cleaned it up a bit and then crafted my own shims with a pair of sheet metal shears. Happy camper...

IMPORTANT: Before you select your shims of choice, you MUST submit a complete set of drawings along with material certifications and MSDS (Material Safety Data Sheets) to Volvo Cars of NA, and then wait until you obtain approval.

Metal. You have to drink three beers to get the clips.

Metal works great. Cut up anything thin and superglue it in there.

Breadclips, wedged in, flew out after ~1 year for me.
