Fiat Fiorino belt tensioner failure
Summary of the thread
A 2008 Fiat Fiorino diesel with approximately 94,842 km is experiencing issues with the belt tensioner, suspected to be due to a defective belt handover. A similar problem was resolved by replacing both the belt tensioner and serpentine belt. It is advised to check the idler pulley and serpentine belt condition, and a workshop visit confirmed the tensioner issue, leading to a successful repair.

Thanks for the tip! I'll check the idler pulley and the serpentine belt. When you say 'similar problem,' do you mean the belt-handover stopped working as well? Was it also the tensioner in your case?

Yes, it was the tensioner. Replacing the tensioner and serpentine belt fixed it for me. But as a precaution I would take it to the workshop.

Thanks a lot! I took it to the workshop, and you were right, it was the belt tensioner and they also replaced the serpentine belt. Cost me 455€, but now it's running smoothly again!

I had a similar problem with my Fiorino. Check the idler pulley as well. A worn idler pulley can cause belt squeal and affect engine performance, putting extra strain on the belt tensioner. Is the serpentine belt itself in good condition?
