Can someone point me towards a comprehensive article on fitting an EWP in a Sprint (search only shows EWP in passing)?
If not, any suggestion as to a good location for the EWP?

But before I take the plunge, is there a way how to test whether my mech pump is working ? I've driven the car for about 10 mins and noticed that the top hose is still cool to the touch. It must have given up the ghost but how to test it?

Firstly have you changed the thermostat?. Top hose stays relatively cool until the stat opens.
Make sure the water level is correct in the top of the stat housing as its the highest point on the engine/radiator.
If you are sold on the ewp idea im sure a few more will come in with the pros and cons of it (me being one of them )

I have fitted an EWP on my Stag and am quite happy with it. Unfortunately at the time I thought it was the mech pump that was at fault (having heard many horror stories) but while dismantling bits to fit the EWP I found that the fan clutch was gone and was probably the source of overheating in that car. Result is that I have a used but good mech pump from the Stag. So if the Sprint pump is knackered I'm still not certain whether to go for the EWP or refit the Stag pump

There is nothing wrong with the standard pump, I prefer 6 vane pumps, but any are fine for a road car.

A non electric alternative is to use a Ford Essex V6 pump, that's complete on it's own and can be mounted and driven by the fan belt.

If you're using a EWP have a look at Rob's (SprintSpeeds) new bracket.

Hi have you used the ford v6 pump on a sprint ?

That alternator bush.

I was just going to say the exact same thing!

There have been two articles in Dolly Mixture over the years but neither are satisfactory installations.

A water pump needs to be mounted as low as possible (to give a good head of coolant from the radiator),
which means on a slant four Dolomite behind the alternator (as shown in the photo earlier in the thread).

It is necessary to fit a remote thermostat, which involves quite a lot of plumbing.
Also, it is very advisable to fit a proper header tank with its outlet plumbed into the bottom hose BEFORE the EWP.
You'll need an electric cooling fan.
Obviously a lot of wiring is necessary fitting relays, switches, etc.

An EMP Stewart pump has a proper mounting flange onto which an adapter bracket can be attached.
These pumps are 200 litres/minute and are rated at 10,000 hours.
You can buy these via Ebay from Summit Racing in the USA.

Ian, thanks for your input.

I've fitted an EWP in a Stag before and luckily (or not!) the engines are very similar, especially regarding the location of the water pump. I'll check whether a location under the alternator is at all possible, otherwise it will be fitted as you and others have suggested. The Davies Craig EWP does have a bracket (bought separately). I'll check on the Stewart pumps as I've read a couple of good reviews on them.
