These videos from Davies Craig could be a peek at the future of installation instructions for the performance aftermarket. Using CAD-generated illustrations, the step-by-step instructions offer an uncluttered visual reference for the installer. No more fumbling with paper instructions with hard-to-read type or fuzzy black-and-white photography. Just set up your laptop or tablet in a convenient spot and run the video at the desired pace.
The accompanying videos demonstrate how to set up a Davies Craig electric water pump with the company’s digital controller and radiator fan. Working together, this system maintains the target engine temperature with more precision than a traditional thermostat, mechanical pump and belt-driven fan. There are other advantages to an electric water pump, such as cooling the engine in the pits without the engine running, no parasitic loss of power from a belt-driven pump/fan and changing engine temps with just a quick program change in the controller.
As you’ll see in the videos, the key is using the Davies Craig header system to replace the conventional water pump, which would just create an unnecessary restriction in the water flow. Some users may just machine out the water pump’s impeller, but this system is much cleaner. Examples are shown using Ford Windsor and big-block engines. Basically, the stock water pump is removed and a finished plate with the water inlet is installed in its place. The big-block uses two ports connected by a Y-hose. Then it’s a matter of mounting the water pump down low by the radiator and routing the water hoses. Provisions for the temp sensor and heater return are also demonstrated.
Davies Craig has a complete line of pumps, fans and accessories to enhance any cooling system. Its system is run on the Power Automedia project vehicle Blown Z, and we’ve seen it used to cool the cylinder heads on Mark Luton’s Outlaw twin-turbo Mustang.
