I now use only Continental belts. They seem to stretch far less than

I get the belt tight by removing shims on the water pump pulley and everything works ok for a few hundred miles, then it starts slipping. I've replaced 3 belts (all high quality Bosch) and one even wore so badly it lost all of it's "wedge" becoming a rubber band.

But removing the correct number of shims is a hit or miss guessing game and is difficult to do in a tight space. I try to get it as tight as I can, with maybe 1/8" available deflection at the midpoint of the belt span.
