Paul Lamar:

Is the pump driven off the back side of the belt?
Is the pump pulley smooth or does it have grooves?

My cosmo pump pulley is made for a multi ribbed belt, not smooth.  The crank
pulley is a combo, multi ribbed to drive the water pump, smog pump and alt,
V-belt for the power steering pump.

Thanks Ernesto.
Can somebody use a paint program and draw in the way the belts are routed.
Or just describe them to me and I will draw them in.

    Hi all,
    This engine has a cast iron water pump! pre 93 vintage.
    Belt system is pre 93 except  for water pump pulley and alternator.
    This is not a series 6 or 93 on as all belt are polly belts on all systems.
     The poly belt on this engine is driving the pre 93 cast water pump with the same rotation as the engine, therefore the grooved side of the belt.
