2000 v70 (D5252T) auxiliary belt replacement
Hi,
My auxiliary/serpentine belt snapped due to the air con seizing. I don't want to fork out for a new AC unit, so have bought a smaller belt (6PK1555/68409) instead of the longer one (6PK1795/68821) for cars with AC. I have the usual trouble of the 10V 2.5D D5252T engine not being covered by the Haynes manual, and I can't for the life of me work out how to: (1) Route the belt (2) Slacken off the tensioner. There's no obvious nut to loosen or place to grab it. It's not possible for me to hold it up and then slip the belt over the water pump pulley. Any advice, tips on tools or belt diagrams would be most welcome! Thanks, Lee |
From Vadis. Hope it's the right diagram - if it even shows up as I've not done this picture stuff before!

Thanks
Cheers Phil.
Not only did the diagram show up, but it's the right diagram! In the end I pulled up on the pulley with my hands, which wasn't pleasant - didn't think of using a spanner of the wee lug that sticks out. My belt follows the same track except missed out the AC pulley (bottom right). I'd be interested to hear more about Vadis and how to get information from it, and whether any other forum members have byspassed their AC in this way. |
Hi. First post in a while - my car's been running OK, so I've not needed to scrounge advice. Till now...
My aux belt shredded yesterday. I got the car the 1 mile home, and am collecting a belt today. Thanks for posting this pic - I'm thinking DIY should be no problem? My AC compressor also has issues, in that I never had it gassed after replacement a while back. I will, so I want to keep the proper belt. Anyone got any comments or tips on fitting the belt? |
On the D5 it's easier if the timing belt cover is removed. There is more space for the tool to move the tensioner and it's easier to get it on to the crank pulley.
The belt shredded for a reason. Either old age or you have a pulley playing up. |
Thanks. :thumbs_up:
I'm thinking (hoping) age. Car has nearly 187,000 miles up, 70,000 of those under my arse, and this belt hasn't been replaced in my ownership. Timing belt done last summer, but at the time I couldn't afford getting the aux belt done as well. I'd had the car parked & idling for a while yesterday (hot sunny day), so I'm guessing that was the final straw for an old belt. The car drove home from where the belt failed - 1.5 miles or so. No power steering obviously, but otherwise it drove as normal, so hopefully there's nothing else serious wrong. For now... EDIT: From the pic posted above, I'm taking it that there's no special tools needed for this job - just use a spanner to relax the tensioner, and fit the belt? I took my failed belt to the parts shop this morning. Of the two listed on their system for my reg number, one was 1685mm long, the other 1795mm. Presumably the shorter one is for non-AC cars? The guy in the shop measured my old belt at 1785mm, but was pretty sure the 1795mm was the right belt. |
From the pic above it looks like the VAG unit unloads with an open end spanner. Speaking from the D5 experience the tensioner is quite strong. Get a good fitting tool and don't let it slip off. Monkey rash if you're lucky, cracked power steering pulley if you're not.

This video by Cheshired5 https://www.youtube.com/watch?v=DLyiYnUkQuE from this forum is great for showing how to do the aux belt.
However, this video is for the D5 and the Torx for the tensioner is a T60. If you have a petrol, the Torx is a T55. |
..............and if it's the older tensioner they have a hex socket.

Thanks guys. And to Cheshired5 for his vid.
So with the tensioner on the D5252T, I take it there'll be a similar locking-hole doofer to keep the tensioner slackened off while removing/fitting the belt? Or will I have to manually maintain pressure on the spanner to keep the tensioner slackened off? Any comments on the belt length? Shop says I can return the one I bought if it doesn't tension properly once fitted, but I imagine 10mm over 1.7m isn't significant enough to be an issue? |
