Need some help finding the part numbers for the 2 auxiliary idler pullys on my car ( 651 ) please. One is between the A/C pump and crank and the other is just below the waterpump. Tried my local parts ppl but the one they sent below the waterpump is to large and they said its the correct one for my car even though its twice the size of the original pully.



Many thanks guys
 
Post the VIN number on here and someone will find the correct part. Local car parts suppliers (and even MB on occasion) can get it wrong. And often do.
 
Find it here :
 
Buy them from MB. They will be 100% correct then and top quality.
 
As above.

Try MB Edinburgh.
 
Update ............ I bought the right pullys using the link above for the part numbers. Just need to fit them to see if the noise has gone on startup or try and find where its coming from. It only does it for about 30 seconds so its not a issue really but i would like to get it sorted before it becomes a problem. Thanks again for the links and replys guys.
 
Could be the alternator pulley clutch
My car has not got the alternator clutch pulley as i thought the same before i decided to replace the others.
