Default LS3 water pump flow diagram

for the guys that have installed a LS3 in there c3's, whats the water pump flow direction?, ie top hole on water pump goes to the top or bottom hole on radiator?

also the 1st start up, how did manage to get water into the engine?, ie the thermostat on the ls3 pump, doesnt let water out untill it warms up enough, so how do you get water in there?

cheers

dave

Top of WP goes to top of radiator.
As long as you dont have a closed heater control valve, coolant will flow through that circuit to fill the motor. But when filling, I left the radiator cap off until the thermostat opened and kept it full.
Note that with an LS motor, the radiator cam will not be the highest point in the system to bleed air out. I had to add an inline radiator cap housing over the top of the radiator. The external tank connected to the heater hose works too.
