Turning torque for engine

Slappy said

I have already been through the cooling system diagnosis I have a three row champion radiator two electric fans . I’ve tried different water pumps, thermostats fans, etc. it’s not the cooling system. I’m just looking for a turning value for turning the motor over. The engine is in the car. The transmission is in neutral, fully assembled belt on all accessories in play

Just want to clarify, when you say “fully assembled belt on all accessories in play”, is it just one serpentine belt?

Only reason I ask is that if this is the case, are you rotating the pump the wrong direction relative to the impeller blades?

Got a picture of the belt(s) routing? Also wondering if you have one really long v-belt going around multiple things and it’s just slipping on the water pump pulley and not driving it fast enough because it’s not making enough contact.

Last thought would be casting sand or sediment from hard water inside the block, or as another asked, hard block.

Hope you find your issue!!!
