Volvo C70 2.0d strange engine whine noise - Page 2

Yes, but I need the tool, 5 eur, plus the bearing pulley tool, 20 eur, plus 2? new bearings, 20+20 eur, plus 2 new stator connector leads, 5+5 eur?...total: 75 EUR at least.

And for 125 eur I have a brand new OEM Denso alternator shipped to my home....so I preferr that rather than spending time sourcing all the parts and the work needed....

Besides, I might even convert the old alternator to an e-bike motor as a future DIY project

we'll see...

Still waiting for the ordered parts (Autodoc) to do the repair.

Installed the new tensioner, alternator and belt...155 eur for the 3 parts.

Started up the car, gave it a few revs and the whistle noise is now gone

Conclusión...the alternator bearings were the cause of the noise.

Thanks all for your help !
