Manual or power steering matters also.

this is my water pump

the correct pulley is the one with : one groove w/o power steering , two grooves with power steering . the crank diameter is the same size as the water pump pulley . 318 is the same

Ok, I have the water pump pulley. I found a one groove crank pulley but the offset is less so the belt won’t line up. I was trying to put a slightly larger crank pulley on to increase the speed of the water pump to cool better.

you need a matched set.
