Hello

Have seen them fitted to a number of both four and six-cylinder Austin-Heal=
eys and they work well.

I have an electric water pump and electric fan on the shelf to be fitted to=
 the Healey Saloon in a month or so, but will be not fitting a controller a=
nd not removing the mechanical pump or thermostat. I still want manual cont=
rol over what happens to a 1948 car.

All components are made here in Australia.

Anyone fitted an electric water pump to replace the mechanical pump?  One c=
an go whole hog with an electric fan, a temperature sensor in the upper rad=
iator hose and a controller.  Takes the place of the thermostat and the imp=
eller on the mechanical pump.

A bit beyond a Pertronix, but still reversible.

Hi Bob -

Just remember that the cooling system is meant to work in balance, so
increasing the water flow through the system often may not actually reduce
temperatures, since the water must flow through the radiator slowly enough
to cool down.  If you push water through the radiator too fast, you might
just end up recycling hot water back into a hot engine.  So if you put a
pump on the car, I would put a supplementary tandem pump, not one that is
meant to work alone.

Best,

Alan

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,

Bob Haskell

The same could be said for the oil pump whose role is much more critical
than the water pump.  Since it is driven by the cam it operates in direct
variation to engine speed and is supplying less oil under less pressure in
top gear at highway cruising speed than when in lower gears accelerating,
etc.  Since there is a bypass valve in the oil system perhaps there is an
abundance of oil being pumped through the engine and this is not an issue,
but at least theoretically the situation is the same.  And for those of us
old enough to remember how old vacuum-operated windshield worked you had
the same deficiency under acceleration when you might most need a clear
view.

Just sayin....

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.

Hi Bob -

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

Best,

Alan

Got some pics of your installation? Those pumps all looked like

Same with my dad's old Model A I drove to high school and JC. When the 
wipers 'worked,' they didn't do shit anyways (but they worked better 
than the mechanical brakes). Funny, even some modern cars haven't solved 
the 'Wiper Mystery' completely (but I don't have any of the high-priced 
marques, maybe they work better and yes, I've tried the fancy bladed, 
silicone wipers and other blades).

                  <div>Just remember that the cooling system is meant to
                    work in balance, so increasing the water flow
                    through the system often may not actually reduce
                    temperatures, since the water must flow through the
                    radiator slowly enough to cool down.  If you push
                    water through the radiator too fast, you might just
                    end up recycling hot water back into a hot engine. 
                    So if you put a pump on the car, I would put a
                    supplementary tandem pump, not one that is meant to
                    work alone.</div>

Davies,Craig recommends disabling the mechanical pump by removing the 
impeller.  See the attached installation instructions - covers just the 
water pump, not the controller or electric fan.

Cheers,

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

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,

Bob Haskell

This is the only one I have for now.  You can see how easily the pump fits
down at the bottom of the radiator.  You cut the existing hose where it
attaches to the radiator with just enough to clamp on to the pump.  Then
measure the distance from the outlet of the electric pipe to where you cut
the existing hose and fit it on to the outlet.  Fits very nicely in the
space which is unusual for any new part bolt on to a Healey engine.
