Good question. Visually looking at the kits one obviously has more gaskets and one extra black o-ring. Looking on the internet I see the two parts seem to overlap at some sites and are used interchangeably. The larger kit has everything the smaller kit includes, plus extra paper gaskets and one blac...

As the car ran well before the head work the best approach is to assume your O2 sensors and similar are good. That said you need to check your work - start with the timing as this is always a tricky part. See here: https://www.matthewsvolvosite.com/forums/viewtopic.php?f=10&t=87735 Then look at ...

Xemodex is a solid, but expensive outfit. I had a 2002 XC70 which was showing signs similar to yours, but ended up being shunt in the CEM. I doubt this is your problem as I had fuse blowing immediately. I have used Xemodex on two occassions for CEM repairs with great success. When I pulled out the D...

"What does the banjo bolt do?" Look at June's picture of the aluminum tube and plastic pipe. The aluminum tube which is "V" shaped has coolant flowing through it if I recall correctly. It is totally sealed from the rest of the assembly. This has a warming and cooling function the...

Inter-Cooler Hose - Volvo (30636959)

Here is what I have done with success: I clean the two plastic pieces up with brake cleaner - one wants to get rid of all the oil. I deburr as required so when I put the pieces together it is nice and clean and makes a tight joint. Then I gently rough up the outside of the area and clean again. Next...

Not sure on the XC90 3.2 transmission. But my work with the XC90 2.9T and XC70s transmissions I have worked on - one can reset the fluid counter and adaptations. I assume your vehicle will be the same - you will know when you get to the screen. My guess is it will be the same or very close. I would ...

Bert: I responded to your other post and you are thinking what I outlined. As boostedxc had success, I would try a module from a post 2002 car. The 2001 was a carry over year and that could be the issue. I suppose it is possible your 2002 has a 2001 module swap. If you search replacement modules on ...

It doesn't matter what transmission you have - you should do a reset of the adaptations in VIDA. By way of analogy: Your TCM has been talking for many years and many miles with your transmission. They have their own "slang" so to speak. The fuzzy logic program has adapted to your environme...

I pulled up VIDA for valve body work on your model. Not as easy as the 2.5T, but easier than the 2.9T. Basically the bulk of the work is removing the subframe. After that, per VIDA, it is just remove the valve body cover and do what is needed. I did some poking around and see solenoid issues and tor...
