Default CDTI air con belt

Hi all,

what length should the air con belt be on a 2005 CDTI ?

I'm seeing 870mm and 872mm

Can either be used ? one maybe easier to get on being slightly longer ???

Pete.

Use either 2mm makes no difference there's plenty of adjustment.

I've never done one. Apparently it's difficult if you don't have a 24mm aviation spanner. Which I've just bought. Difficult because of lack of space.

Fitting the aircon belt itself is easy just pay regard to the torque setting on the tensioner bolt. The pain in the backside is the fact that you have to remove the auxillary drive belt to fit it!
If you can get a good purchase on the 24mm tensioner bolt, with a helper to hold it, you should try and just slip the aux belt off the crank pulley only, fit the new aircon belt and then replace the aux belt. If you are careful the belt will hopefully stay correctly positioned around the other components, in any event check it to be sure. You can adjust the aircon belt afterwards, in readiness you can cut the old aircon belt off out of the way. A piece of timber fillet is useful to wedge between the 24mm spanner and the inner wing to stop it slipping off the nut.
Good luck.

the belt is not there ..it was cut off already so its a hot car
im afraid if i go through all of them steps it might start making noise hence the reason the former owner had it removed
am i mad to chance it ?


thanks

If you are fitting that belt, your have to remove the other belt to fit it - the ac belt has to go on first, so best to renew both belts at the same time.

Its not an easy job, but it is relatively straight forward. It is made difficult because of the poor access and the struggle to keep it on so many pulleys.
