D5 Aux/Cam Belt fix
Hi everyone!
I'm in the market for a Diesel XC70 P3 and I already know the horror stories of the snapped aux belt that takes down in sequence the timing belt and the whole head. What I've heard or read somewhere is that finally on D5 engines they put something like a plate in between the 2 belts in order to keep them separate and virtually have no more timing issues in case of a snapped aux belt. If this is true, do you guys know when this upgrade has been implemented? What MY should I look for in order to buy one with the upgrade? Thank you! |

Oh that's a shame, thank you anyway for the explanation.
Do you know how this affected the risk to have a snapped aux belt? I mean, does the new service interval really lower (or maybe eliminate) the risk of such a catastrophic problem? |

Yes generally it does .. There is always someone who will say theirs broke after 30000 miles but we don't know the facts ... in my experience working professionally with 1000's them the 54000 mile interval works fine .

With your experience Clan, would you change it a 5 years/25 k miles. Or maybe (for example) ask the garage to ask the garage to listen to tensioner by stethoscope to see if it is spinning true? I realise the importance of the change, but it’s not that cheap (£200-250) on a 12 year old car that’s not now worth a lot. |

You can change the aux belt & tensioner for around £60 (dayco parts - identical to OEM). See my progress thread when i changed my tensioner and i couldnt tell the difference in visual appearance or tensioner operation between the OEM volvo one and dayco replacment - so it had faired very well for 5 year old. However for £60, get it changed. Cambelt is 10 year/108k

The only one which should be used are the one with VOLVO stamped on them ... volvo parts are nearly always to volvo's own specifications which are better than the ones you mention .. at least you have some comeback if it falls apart .Dayco aren't going to have any interest whatsoever .. you get what you pay for i have found in my 45 year Volvo career .
