Re: [Healeys] Electric water pumps

[Bob Haskell via Healeys <healeys@autox.team.net>]

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,
