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.
