Computers run virtually every system in a modern vehicle so why not let a computer control the cooling system of your vehicle – new or old?

Maintaining a constant temperature in old school engines has always been the bane of their owners’ lives – Clevelands, big block anythings, small block Chevs and most of the pre-aluminium brigade, all have their overheating
crosses to bear. At the end of the day, it comes down to suffi cient heat exchange area, adequate fl ow through the coolant system and, most importantly, enough air fl ow over the heat exchange surface to remove the required level of heat from the engine coolant. Most conventional water pumps use a simple pressed steel impeller that is spun by a pulley driven by the crankshaft, which means that despite the pulley ratio, the water pump turns in proportion to engine speed.

This is all well and good at higher rpm but at lower engine speeds, coolant fl ow can be less than optimal and these are usually the times when air flow through the radiator is at its lowest rate. Needless to say, when the engine is off, coolant flow ceases altogether and this creates pockets of steam within the cooling system
that can lead to burst hoses, overfl ow pipes that resemble out of control fi re hoses and at the very least a huge steaming puddle on the ground. The talented team at Davies Craig (the same company renowned for producing Thermatic® fans for over 40 years) put their collective grey matter together and developed a remotely mounted electric water pump capable of completely replacing a conventional mechanical water pump. This may not be a new idea but the fact that the pump can be fi tted to any engine and remotely located if necessary, makes it a unique
and effective solution.
