Hi,
Hope PM is ok.
some time ago i was enquiring about pulleys/belts because of an engine vibration and you gave the perfect DIY link for removal of serpentine belt- http://www.benzworld.org/forums/w210-e-class/1542201-my-annoying-v6-m112-rough-idle.html
I did nothing because my mechanic said no need to - I am about to go at it myself now- anyway this is my question - Is the harmonic balancer and belt tensioner the same - or which is which?
thankyou
Darragh
