HDi Timing Belt change

Ok will get all that done first. Thanks fellas

Do the GSF water pumps not come with gaskets then?

How long should the aux belt tensioner and pulley last for? As I may do it all while I'm there.

Likewise, engine mounts? I sometimes do get some jerkyness on easing off the throttle and again when depressing it. Came to my mind that it could be engine mounts. Don't think it's clutch.

The only mount that normally gives problems is the lower donut one and you can gain a good impression of it's health by looking at it. If it looks OK and you are unable to "rock" the engine backwards and forwards by grasping it, then it is most likely good. You can also get a good idea of how good the mounts are by revving the engine and observibg how much it moves. Oil leaks normally kill the lower donut and bad ones will have their rubber insides spilling out the sides.

The lower mount replacement job is a bit long-winded, needing the RH driveshaft to be removed so it's not a quick side-job you'd do whilst swapping a cambelt in any case. It's a big enough task to be carried out on its own merits.

Generally, with aux belt tensioners, if they look and feel Ok when you take the belt off, you can leave them be. Again, they are almost a big enough job to be tackled in isolation.

Concentrate on the cambelt for now Toby

Sorry to throw this in but does anyone know if the C5 2L HDi is the same as the Xantia's?

The early one yes. The same 110bhp 8v engine. Later ones used the 136bhp 16v HDi

Citrojim,

Id just like to add, that on HDi 110 cars, the TOP small mount, the Tourque link one thats got 3 bolts through it onto the top of the suspension turret, this one breaks quite commonly....

The HDi 90 doesn't seem to break it... Luckily its only 26 quid or so from the Stealer...

Thanks Paul, very valuable

I guess it's the same one that fails with some regularity in the Activa and 2.1TD

Yes Jim most likly, Im sure the 2.1td (seen as the HDi replaced it) houses the SAME mounts...

A Pleasure..

I'm looking to my Belt on my 2.0Hdi 8v.

Can anyone confirm the crankshaft bolt size, is the same size as the 1.9td 22mm??

thanks

Yes Im sure but not CERTAIN it is... the Crank WAS actually carried over from the TD XUD!!

Ive a HDi belt to do here as well...

The differences I've noted seem to be with ancillary systems. For example the EGR system on the C5 is inside a water jacket that feeds the heater, I guess this speeds up the heater warming as the EGR is normally used at low revs/part throttle when the engine will be slow to warm up. The C5 also has a 'Dozer' valve on the induction system which I'm told is to help with EGR function and help minimize the shut off shudder.

Doing the cambelt sounds similar to the 2.5 TD in that vernier pulleys are used, the idea with these seems to be that once the belt is tensioned the 'vernier' should be in the middle of the pulley slot.

Will be doing my C5 (DW10ATED) soon.

Steve.

My Xsara has this too, and I have found since disconnecting the EGR the coolant is slightly slower to warm up in cold weather.
