If you recall -the stock Mazda water pump has a 5/8" dia hole for recirulating water through the engine while the thermostat is still closed. Once the coolant heats up, the thermostat opens and also "plugs" this 5/8" hole. Racing Beat (amongst others) state that if you do not use a thermostat and fail to plug this hole you can loss 20% of your cooling effectivness. So the question is do you plug this hole or not? Ed Anderson ----------------------- Ed, I imagine the hole is open, but it's also sitting in a box in the corner of the garage :-) Since he's removing the entire water pump housing, the whole silly thermostat business is gone. Doesn't that just leave you with a simple g'sinta and g'souta? Rusty
