Dear friends, I want to use a electric water pump on the engine test stand, but those aviable e-pumps do not use the bypass and were only bolted on the 2 big water holes at the block. The third upper hole is blocked. So I am not sure to run the engine without the robert shaw thermostat or with it. Normaly I would say the thermostat in this combination makes no sence, but I can not find a intern engine water flow diagram. Thanks for your help.
