Gates belts part numbers for stock pulleys
 

Just replaced my belts and I like to use Gates or NAPA. The Gates part numbers for the stock pulleys are:

K050530 (air pump, water pump, alternator)
K060408 (a/c, power steering)

You wouldnt happen to know the part numbers for the belts if you use an oversize waterpump pulley (4.063" diameter) and alternator pulley (2.25" diameter at deepest part of groove, 2.72" at outside edge of pulley). Picked these up on ebay - cheap. I had them hard anodized with some molds we sent in where I work. No data was provided by vendor re: belt specs.
thanks,

Don't know the numbers but it's no mystery to figure out. Remove the belts and then adjust all the tensioners to half way. Wrap a piece of string around the pulleys just as the belt would and then measure the length of string. Go to the store and tell them you need a 5 rib or 6 rib belt that is X inches long. They should be able to help you.

thanks, that was my next step the next time I was under the hood to do some work. you know, sometimes you get lucky by simply asking the question. that theory works better for cars than on women!!!
