Pully Question

1499 Views 13 Replies 5 Participants Last post by  Merc600sec
The waterpump just went out on my 96 S600 with 105k miles. Not bad. Fortunately for me I was a 1/2 block from the house. I'm looking up parts and I need to replace everything and have found all but the tensioner pully. My questions are:

1) Are the pullys for the idler and tensioner the same?

2) When replacing the thermostat, do I have to replace the housing too?

3) Do you reccommend replacing the belt tensioner mechanism too?

Thank you for your input.

Wow, the old one was a bit of a mess.
Were you able to recover all the bits or are there still bits circulating in the system?
