Final Question. I see the light.
Im working on a 2001 chevy v6 vortec.
The pump has the main input, and 2 smaller connections on top.
It looks like the coolant leaves the intake by a hose that heads to the heater core, then to one of the small connections on the pump.
and the other small connection is a hose from the front of the intake. I assume thats the bypass?
Do those two small lines empty right into the vanes of the pump, and then into block again?
So all the tubes on the pump are inputs, and the only output is there at the block? I think I got it
