How many of you had your belt tensioner replaced?
Hi fellow mb pals, how you all doing? I hope everything is ok with your benzes,my question is how many of yo had your belt tensioner changed for an updated version? my car is a 99 C43 AMG but buildt in late 98, so I guess I have the old style tensioner,the car is now on 52,000 miles aka cirka 82,000km.
The new tensioner parts number is 112 00 970 I think it was, last digits ends with 970. I was thinking of changing this part for safety reasons only.
Is there a part that tenses out the belt to be tight, it looks like a mini shock, described as a tension mini shock I think>? please describe it for me or send me a picture from DETALI RUSSIA if there is such a part?
I also want to know if you had to change anything else such as?
waterpump
acc idler pulley
thermostat
multi rib belt
Harmonic Balancer
Anything else I have forgotten? please fill in
happy motoring cheers.

Hey bud,
I had to replace both the HB and and the belt tensioner. The belt tensioner was gone for a few weeks before I repalced it. It made a loud ticking/banging sound when I would have the HVAC system running. Not sure how bad they get but mine wasn't a danger to the vehicle at the time. In time I'm sure it could get worse and cause problems. It was an updated part that I replaced it with.
The HB recall was done when I bought the car but the damage it caused required me to replace the upper oil pan..catch this one beforehand cause it could rough things up when it goes.

The harmonic balancer is something worth keeping an eye on, replace it if you have any doubts about it's condition.
The belt tensioner is pretty reliable on the M112 and M113 engine. usually the damper inside the tensioner wears out and it becomes noisy at idle. It's life is also shortened by a leaking oil filter housing (oil gets inside the tensioner). I would only change it if it fails, no need to change it early.

The top arrow indicates the tensioner and the bottom the Harmonic - bring in a new belt so you don't have to pay like $68 for it ($20 or so at Auohausaz) Campaign # 2005020003

The upgraded tensioner is easier to use vs the older one . The older one uses the stupid star bolt which strips as well when you try to turn it with the ratchet and star socket.
