Does anyone with a Renesis know for certain the direction of water flow out of the pump?  Does water come out of the engine at the top outlet (thermostat) or out at the bottom outlet?

I have totally confused myself and I am thinking this may be part of my cooling issues.  I have the top hose (thermostat)  connected to the top inlet of the radiator.  If this is the cool water inlet to the engine, it is hooked up backwards and would cause me to suck air from the radiator.

Thanks,
