That’s exactly what happens. Aux belt gets wrapped around the crankshaft pulley and takes out the cambelt.

Snapped cam belt on its own = destroyed engine Either way, the outcome isn’t usually a good one.

Aux belt often doesn't take out the cambelt, as previous posts indicate. Inconvenient only.
I've never heard of a cambelt snapping on a D5. Have you or any others? That discussion aside, wtaf is going on with these multiple failures at low mileage - again the first time I have heard of this. Tensioner issues? |

Is the issue perhaps mainly with newer stop/start vehicles ?

The belts are made dayco in Italy as is the tensioner from what I could work out from the genuine parts I last fitted.

This issue plagued these since this design was introduced. Older engines with the much thicker aux belt didn’t suffer that often tho if they were neglected the aux belt could rip the cambelt tensioner from the block!
When this set up came out in 2007 there was recall after recall for the tensioners as these were failing or wearing the belts out. Why they went to a two belt system I don’t know there was nothing wrong the the thicker single belt set up. Ford cost cutting and no dought so called engine efficiency rubbish.

I don't perceive it as having been a truly major problem as long as the recommended belt/tensioner/idler changes were carried out at the recommended service intervals (108,000 miles for cambelt, 54,000 miles for the auxiliary ?). Not sure when the first Volvo (D5) stop/start vehicles were introduced (2009 ish?), but in view of the apparently more regular failures I do wonder if it may be the extra forces applied to the belt/s during stop/start which is increasing the problem ? Indeed I think the auxilliary belt interval may have been reduced at some stage to 54,000 miles by Volvo from what originally may have been, as with the cambelt, 108,000 miles ? The original question seems to be what is causing the issue ? The above are just some thoughts on my part, but I do appreciate that a little knowledge (again on my part !) can be a dangerous thing. |

Perhaps auxiliary belts do fail more regularly in other manufacturers stop/start cars, but owners don't have the further repercussion of a wrecked engine ? Not trying to justify my point, just add to my observations..
