You might consider a slightly shorter belt. Look at the number on the back of the belt, should be
something like 17AVxxx where "xxx" is the length in mm. Take the belt to a real auto parts store
(not one of the chains) and ask them what they have in a slight shorter belt. I had to do this on
my Toyota when I installed a new alternator. I needed something longer so went from an 890mm to a
I carry a spare belt or two with me, since if I need to replace one on the road, not likely to find
one off the shelf in the middle of no where.
