Brett,

the adjustment is made via the addition/subtraction of shims in the water
pump pulley itself (it comes apart). Kind of like the old Beetle belt
adjustment system. Deflection, when thumb pressed against belt, should be
5-10mm (from manual)
The bolts that hold the two halves of the water pump pulley together should
be tightened to 14 ft lb.
