Yes, the fan belt is on the water pump keeping it operating as the =
electric pump pushes the water through the mechanical pump.

Hi Bob -

I assume you are using an electric pump in tandem with the mechanical =
pump?

Guys,
I have tested the temperature of the water at the hose coming to the =
radiator and at the bottom going up to the inlet. While I do not have =
exact information because I am not in Florida, I can assure you there is =
a very nice differential between the hot incoming and the much cooler =
out going of the radiator. Other on this list who are using the Davis =
water pump are considering removing the fan altogether. I have removed =
my Texas Fan as it is no longer needed. Try it you will like it. =
Remember modern automobiles have electric pump moving water to and from =
the radiator as they were designed without a fan/water pump.
Summit Racing has the water pumps in stock.

Alan,
I have the same concern. I sent their US rep an email asking about =
that. Seems like there ought to be a temperature sensor in the lower =
radiator hose to look at the temperature drop between radiator in/out. =
The temperature drop would be affected by (electric) fan speed and the =
flow rate.
They sell different size pumps. Based on their table, the EWP115 =
(115liters/minute maximum) is what they recommend for engines between
2.0 and 3.5 liters. Anyone know what the flow rate is for a stock water =
pump?
Cheers,
