The Water Pump Situation

By Damien

from Leylines # 30
As summer and its cooling challenges approach, I investigated the P76 V8 water pump situation and have found that there are two alternatives:
• Replace with a reconditioned water pump
• Replace water pump with electric Davies Craig unit.
The costs for each are similar.

New water pumps

I could not find a source for 'new' water pumps. There have been rumours regarding new castings but I could find nothing concrete to substantiate these whisperings.
Our President informs me that at the Easter meeting (last year) he bought a new water pump, which originated from old Fred's parts at Kiama. Alex says that the pump looks different to the others and has different casting marks.

Replacement water pumps

.
There are ‘reconditioned’ water pumps available and they can be obtained from JED Motors or Minibits (same company, two names) in Melbourne for around $250.
• JED can be contacted on (03) 9707 1666
Morwood Motors in Canberra also have these in stock and quoted $250.
• Morwood Motors can be contacted on (02) 62806876
I looked at the other clubs' websites but couldn’t see any listings for water pumps.

Electric water pumps

Davies Craig manufactures an electric water pump, which replaces the function of the existing water pump. You do not remove the existing water pump, but remove the impeller inside it, and connect the electric pump into the lower radiator hose.
I know of one person who performed this modification to their ancient Ford Cortina and raves about it. It remedied 10 years of cooling problems.
Tony from Morwood Motors also advises that this would be a better option to fitting a reconditioned water pump, and that it also frees up a few more horses of power.
Davies Craig electric water pumps retail for around $280 at Repco.
Let me know
If club members from other states have any info on newly cast water pumps, pumps from other cars which fit or other info on water pumps can they please email me at: dchaas67@yahoo.com

More on Water Pumps

From Leylines # 31
In December's Leylines, Damo discussed some of the pros and cons of water pumps for the P76.
Alex has turned up some more information on the Davies Craig electric pump.
Davies Craig Releases Upgraded Electric Water Pump
The Generation III of Davies Craig¹s Electric Water Pump (EWP) has been released.
The advantages not only include an exclusive design carbon graphite/silicon carbide long-life mechanical seal, but also many upgrades which have been incorporated to raise the quality and durability of the EWP to the level of demanding Original Equipment standards.
All internal parts of the EWP exposed to coolant are stainless steel and the higher power electric motor has sealed bearings, with the pump body and impeller being made from heat stabilised glass-filled nylon. This improved pump is now fully serviceable.
Performance-conscious drivers can now take advantage of the EWP power gains, confident that the unit will provide years of trouble-free service whilst improving vehicle performance, fuel economy and cooling management.
"We've put in considerable investment to upgrade the design, features and production methods that make this generation three model the very best EWP," says Davies Craig's Ray Brown.
"It's now a truly world class unit from every point of view."
In the short time this innovative solution to vehicle cooling has been on the market it has proven to be successful in the performance sector (cooling the class winning Ferrari at LeMans) and is attracting increased attention from Automotive Manufacturers for adoption as Original Equipment.
By installing the EWP, users will not only improve the cooling efficiency of their vehicle but also have the immediate benefits of enabling the engine to transmit power, which used to operate the outdated belt-driven water pump, to the road. Power gain for a typical 4 litre engine can be up to 8 kW.
Matched with the Electronic Controller, the EWP provides optimum cooling performance management independent of engine speed for maximum performance. This smart device has a sensor that monitors the coolant temperature that you set and regulates the EWP speed to match demand. An example of this enhanced operation is the way the Controller keeps the EWP turning after the ignition has been switched off to control engine cooling after a hot shut-down.
Converting a vehicle is as easy as removing the lower radiator hose together with the thermostat and disabling the mechanical pump. The lower radiator hose is then cut for the EWP to be fitted in-line, assisted by the many universal fittings included in the standard kit.
The compact Controller is easily installed and the temperature sensor is fitted to the top radiator hose or thermostat housing. The rest is all long-term performance improvement.
The Davies Craig Electric Water Pump is a top example of Aussie world-class smart technology putting innovation to work.
