      3.2L Alternator Decoupler Tool

      Hi All,

      I'm going to pull the manifold on the XC90 to reseal all the green seals. Hoping that might cure the very occasional P0420/0430 code that pops up once in a blue moon and only when the car switches to closed loop.

      Anyway, as the XC90 has 150K-ish miles, I'll service the alternator while in there. VIDA says that I should be looking for an M10 XZN/Triple-Square to get the decoupler pulley off. I do have the splined tool already, but FCP has this kit. This should do it?

      It'd rather by one semi-decent tool then a whole kit of iffy.

      I noticed that FCP also now has a similar kit with the T50 for the rear belt drive pulley.

      FCP also also now has the VR/brush pack for the 150A/180A amp alternators. $54 is cheap insurance.

      Many thanks!

      I used that decoupler tool from FCP and it worked flawlessly. Can't speak to the other two kits.

      Thanks!

      The kit for the rear belt drive is the right stuff, it just need to be a darn good T50 as the screw is crazy tight!

      Just to be clear, are you saying that the de-coupler from FCP, the CTA 8088 works on the 3.2 alternator decoupler? I'm double checking because FCP kicks it out as not being suitable for my car (3.2)

      FCP has their information wrong since the 3.2L has TWO decoupler pulleys... and their database likely only has one place to enter the fitment.

      One decoupler is on the the alternator, which should take a M10 triple square

      The other drives the rear accessory belt system. IIRC, this uses a T50 Torx according to this idiot:

      Both decouplers use the same splined counterhold.

      Thanks for that; mine is on it's way.
      Are the decouplers rebuildable at all? Replaceable bearing?

      My guess is that it's not practical to rebuild. There are clutches and seals inside, and my guess is that trying to find parts is going to be the deal breaker.

      I like to rebuild when possible, but I think each decoupler pulley on the 3.2L is $100 from FCP. Not cheap, but even trying to rebuild seems like it's not much fun. Plus, each one of these is kind of a bear to get at.

      Yes, they're a challenge to uncover. I was at the JY the other day, and someone had gotten some of the stuff out of the way, so thought I would get a little practice on the '07 there and see about removing one. I couldn't believe how many bolts held on the AC compressor and it's mount. I finally got to the decoupler, and found I didn't have anything to get the protective cap off. That car or decoupler will probably be gone when I return. No biggie. When I left they asked what I got, and told them I got dirty and an education

      The A/C bracket on the pre-2011's looks like a nightmare. Fortunately, Volvo redesigned it for 2011. Much easier.
