How do you "bench test" a electrical water pump while still on motor? Never had to do that it before. its on a 4.3 typhoon. heads are removed and there is no coolant to circulate. thanks

I'd get a couple of buckets, one full of water and one empty to catch the water, and a bunch of hose to reach the buckets. Put the full bucket as close to the pump as you can (like right on top of the engine), as you don't know how much suction head one of these baby's has. Make sure you have the goesin and the goesout of the pump in the right bucket, or all it'll do is blow bubbles at you.

Yeah definitely put liquid through it, if you cavitate the pump it may ruin the bearings or burn out the motor. Should be able to run it right off of a car battery though.

so I should just be able to turn the key to the on position and it should run right?

Dunno...is that how you wired it?

I would think so, normally it would be wired like that.

not sure as i didnt wire it. I do have 2 wired going from the front of the pump and it looks like they go into the radiator
