Hi all! I have a question I am hoping someone can help me with. I just bought a 2000 ML320 and the belt came off while driving. After further inspection I see that I am missing 2 of the 3 bolts that hold the pump on and that is the problem as the pulley is wobbling. What I need to know is what size are the bolts I need? Can anyone help? Thank you in advance!!

 

There are four bolts that attach the pump to the timing case cover. These bolts must be purchased at the dealer. Do not use any other bolts.

You must remove the pump and check to see that none of these bolts broke off into the timing case cover.

 

What are the part numbers for bolt #59 for the reservoir and bolt #29 for the bottom front of the pump?
