"We would like to advise:
There are two belts listed because GMH changed the tensioner pully diameter and the breakover date is very short.
The information that I have been able to find is
10/2000 - 12/2000 = 2825
12/2000 - 07/2001 = 2810
So the build month makes a difference
Please do not hesitate to contact us again if we can be of further assistance."
Above it my response from Bosch. Pain in the arse, thanks guys. Im looking to change my belt as i have had a Gates V belt on for about a year, but i dont like it, slips too much, especially on start up. I heard the Dayco or Bosch belt is much better.
