Pully Question

1498 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.

1...No different sizes different mountings
2 not unless you have significant pitting and surface deterioration..
3 Yes because if you dont it will come back and bite you..

Question.. what makes you think it is the water pump that has failed ?

Brett is the guy to ask for guidance and help on this..

then thats a belt replacement first.. not a pump... the idler pully and the tensioner pully and the water pump you can check when you have the belt off...
