Belt Help!!!!!!

As far as the crank pulley grooves go, they appear to be the same, but only one groove is being used on the crank pulley. To me it looks like the belt sits to high on the alternator pulley and isn't flush, but I put one on there that was and it still squealed. I tried to take a better pic of set up. See below.

I can't see your crank pulley, but assuming the ps is pulled by it, why not try--just for an EASY & CHEAP experiment--running a short belt JUST from the water pump to the alternator? This will give a MUCH greater contact surface for the belt on both the alter AND water pump pulleys, AND eliminate any slippage caused by 2 apparently different-diameter pulleys on the water pump.

Pls. DISREGARD this suggestion--I had not seen page 2 of the thread. My bad...sorry!

Also, IF the alter belt runs off ONLY the water pump pulley, then the 2 diff diam's on the water pump pulleys would be a non-issue. Therefore, I MUST agree with others' diagnoses that the alter pulley MUST be changed to fit the belt.
