hi guys
Well im now the proud owner of 97 p reg 1.9 td xantia just brought it over the weekend anyway the aux belt top pully needs replacing which i knew about does anyone know how to take the belt off as mine is the self adjusting type with aircon only ive looked in my haynes manual and it says losen the bottom pully bolt and the bottom bracket bolt and then adjust the manual adjuster to remove the belt when i looked at mine there was a lower pully bolt, but no bottom bracket bolt and the belt stays tensioned where do i go from there guys. Also is it much of a job to replace the top tensioner pully or do i have to replace the complete bracket complete with the 2 pullys like ive been told.

When I replaced my aux belt I found that the Haynes book made out my auto tensioner was the arrangement given for the 2.1 td. Even though mine is a 1.9 td.
Try using the pics and description for the 2.1 td.
cheers.

On the earlier cars, you had to undo the bolt in the centre of the pulley, then another one below the pulley, then wind out tensioner bolt (tightening the belt) until you can insert a bent rod through the holes in the auto tensioner (which you can hardly see!) - then wind the manual tensioner back in to let the tension off. On refitting put the belt back on (refer to the routing diagram in Haynes!) then tighten the manual tensioner until you can remove the bent rod from the auto tensioner, then tighten down the manual adjsuter mounting bolts. The 2.1 system is a bit different, and may as said above be fitted to later 1.9 cars. Don't know how that works, as not played with one, but it may be like that on my car.
Changing the auto tensioner (on the early set up at least) is a pig. You have to remove the hydraulic pump and the alternator to get enough room - and we had to drain the cooling system and take the top hose off to get the alternator out....

Here's the '1.9' setup I've worked on:

I think this is the '2.1' set up:

Which you have seems to depend on how many fixings there are on the alternator (3 or 4).
Ah, I see now that the 2.1 set up is completely different to the 1.9 type. Sorry, no idea how to get it off! Looks like there might be a big spring in there somewhere (item 5 is listed as 'tensioner', item 3 as 'tension roller'). Studying the diagram it appears that the mounting for the roller is integral with it, and the tensioner is bolted to that from the back, so looks like unbolt the top of the tensioner, then unbolt the roller and it should come away, roller and tensioner can then be separated. Not sure if it will be under tension or not though!

What you're calling the 2.1 setup looks suspicously like what my '97 has, i.e. 1.9 with aircon.
Do all 2.1s come with air-con.

I expect all 2.1 come with aircon, as they are mostly Exclusive. There seems to have been a big overlap when 1.9 cars could have the 1.9 or 2.1 set up - my 97 TD VSX has the '1.9' set up. I just used the 1.9 and 2.1 tags to differentiate - these being the set ups the engines had when introduced. As we well know ... subject to revision without notice!

Many thanks Richard
Thanks for the diagram Richard this is a great help now i can get on with the job this weekend without to many probs. Mine is the 2.1 setup the same as Kowalski,s on a 97 1.9 td with air con. and its the tensioner roller on mine thats gone, anyway now i can see by the 2nd diagram what i have to do so i dont think it will couse me to much of a problem although looks as if it could be a bit fiddly. ill let you all know how i get on
thanks agian

Hi all i've got a 2.1td and i found it a real bugger to change the auto tensioner i've left the job at the min the problem is is that the hydraulic compressor is in the way and my big saussage fingers can not get in. So i just put the eccentric roller to the max not the right thing to do but its working for now, is the 1.9 set up the same with the auto tensioner the same where it uses the compressor as leverage, i'd love to hear how you get on

hi pazuk
yes my 1.9 td is the same setup as your 2.1 and i stripped it down tried to take off the h/c pump could,nt do it tried to take the tensioner off could,nt do it lost a 9 mm allen key somewhere between the alternator and aircon pump so ive decided this job is to much for me now i have the problem of trying to get the fanbelt back on so,s i can drive the car to someone who knows how to do it so any help on getting the belt back on whould be much appreciated the problem is getting the belt on and i cant get it over the pullys becouse it goes to tight and the tensioner wont release back

Remove one of the alternator bolts so that it will 'swing' in the conventional way for adjusting. Fit the belt (easing it on a couple of Vs at a time), then swing the alternator back and secure.
I had the same problem - fortunately, the tension was about right with the new belt as set!

Pete,
I changed the spring loaded tensioner on my 1.9 turboD. I hadto remove the cooling pipes off the oil cooler (block side of oil filter) and pull a plug off a sensor on the block. I think I took some other water hoses off too.
You need to clear away as much as you can to gain access from the right side of the spring tensioner in order to get at the socket head screws. The bottom (roller end) screw can line up with a hole a web in the block casting, I used a 3/8 drive on a T bar down the narrow gap down the left side of the engine. The 3/4 (or might be 1/4) located in a square hole in the roller mounting plate. Rotate the roller plate to compress the spring until the bottom screw lines up with the hole in the web. You can just about do it with 3 hands. Or the t bar under your chin. Or lift your leg up and pull it down under your knee (if you can do that you can join a circus)Its a right pain and needs loads of patience.
When you've finished. You've just got to put the cooling system back together and top it up. Don't forget all the bleed points.
I purchased a long claw tool so I could retrieve all the tools I dropped.
To put the aux belt back on I found it easiest to take the idler roller off all together then wrap the belt around it. Bolt the idler (eccentric) roller back on with the belt wrapped around it. Then use a square drive to turn the eccentric roller to give the right belt tension (a 6 mm allen key or drill just slides in the hole in the tensioner roller plate to block alignment hole).

hi guys and thanks kev
Well ive managed to get the aux belt back on tonight [:D] i had to drop the engine to gain better access to the pullys then used my 1/2 inch drive rachet and a 1/2 inch to 3/8 converter located the square hole in the tensioner arm gave it a twist then after a lot of struggling managed to get the belt back on then bolted the engine back up job done now just going to let someone else do the pully for me now it,s just to much for me my other n xantia td without air con is much easier to work on more room under the bonnet. and kev i tried all night friday night then all day saturday to get the tensioner off and did,nt suceed also i have the complete bracket and rollers to put on and i could,nt even get the hydrulic pump out undone all the bolts and pipes and it did,nt move then i looked at the position of the alternator in between the h/c pump and the air con pump couldent even see the mounting bolts then had truble to get the aux belt back on so i decided to leave it to somone who knows but the thing is i shall watch him change the pully then nextime if there is one i can do it myself
