Serpine belt size
 

I have either March or BBK underdrive pullies on my 89. I am in Baghdad, and my wife is in Germany with the car. She says the belt is wore out and I remember the stock belt being too long. I need to order the belt online, but don't know what size I need. Could anyone help?? Thanks.

My suggestion would be to have her measure the routing with the belt installed (because the tensioner being unloaded when there is no belt will throw off the measurement and the belt wont fit). If the belt broke, measure around all the pullies (skipping the tensioner) and add a half inch or so to compensate for the tensioner. The best way to measure is to route a piece of string in the belt route, then measure the string with a tape measure.
