The of this post is to assist who may have some variations the different tutorials on the web for changing the 2.5T timing belt. I ran a few surprises and wanted to share with others who might be the same thing. This a whole tutorial, there are of those out there.

It#39;s supplemental info for people who run into similar snags.

2005 XC90 2.5T

Number

This made a for me. There are timing belt for engine numbers up to 3188688 and for 3188689 and beyond. The difference is the tensioner.

My engine number was on the on the lower timing belt If that#39;s missing it#39;s on the of the engine block and a pain to from what I understand.

Below are the part numbers for the timing belt kits.

part 30758261 (up to engine 3188688)

Volvo part (engine number 3188689 and

I personally don#39;t care you get the parts from but this does a good job of showing the the YouTube tutorial, and explaining the number issue.

I got my parts from this place and I recommend them. They sell on ebay and ship

Serpentine Belt

All the tutorials I stated the tensioner could be with a 14mm wrench. not if your tensioner has a large T60 inlet like mine and one.

I ended up taking a Volvo owners advice and together the tool I needed there doesn#39;t seem to be one out I bought a 1/2 drive T60 bit like one.

However just putting onto a 1/2 breaker won#39;t due to the limited clearance. So if you hammer the bit out of the socket you are left with a T60 bit that will fit into a 3/8 drive socket which fits in the small space. have to tape the torx bit the socket so you don#39;t lose it. you get the socket into the tensioner I a 19mm wrench onto the for more leverage.

Just towards the front of the car and the belt come off pretty easily.

Damper / Harmonic Balancer / Pulley

I tried to get this off but finally gave up. I left it on as have and it was fine. I did however to remove the lower plastic (number 1 in the below image).

It#39;s held on by two 10mm You can#39;t really see what doing but you can feel around and get a wrench in there pretty Once removed it allowed me to the new belt around the damper and get it on the crankshaft gear.

Make the belt is actually on the gear. are a few spots it can get snagged behind the You can#39;t see so it#39;s all by touch but not too bad.

I#39;m not sure if easier than removing the but I didn#39;t have an impact so it was my only option.

Tensioner and

I removed the old ones completely taking the old belt off. It to have less for it to snag on. I waited until I had the new belt on the gear before putting the new on.

This worked great and around the new belt is easy, you push it out of the way to install the new tensioner and

Those Fun Timing Marks

I had all screwed up during the process. to the fun I moved the crankshaft trying to the damper so I had to make sure was right. The lower timing is the hardest one to see. This does a pretty good job of it to you. I lined up the mark on the block, through the valley of the and to the mark closest to you.

This lined up to a mark I had put on the damper so I was convinced it was correct.

The cams move pretty so I was constantly having to reset to make sure everything was While putting the new belt on it a few times to get the upper cams in the spot. One tooth doesn#39;t like much but it will be noticeable on where the timing are. Just double and check everything is in the right

Once you get it right set the belt and tighten the center bolt on the

Rotate the engine twice to see if the timing is okay. After the time make sure the marks are all in the right spot.

Timing Belt Cover

This stupid thing is a It just takes messing it until it falls into It needs to sit behind the damper means shoving the cover there and your hand to get it to behind the damper.

After 10 minutes mine finally into place.

Useful

Some of these are XC90 and some are other models but all have useful information to do job. This certainly a complete list but these me.

Final Thoughts

Take time and you should be fine. remember before you button back up and turn that key check everything. It#39;s not a job but if done wrong it can be very and EXPENSIVE to fix. Good
