The benefits of installing an electric fan are considerable - it replaces a mechanical fan and saves much of the energy that the old fan absorbed, and so boosts available engine power, or fuel economy, or both. Plus, the electric fan will be quieter (especially for the long periods when it’s not running at all!), and it can carry on running after engine shutdown, to help overcome heatsoak problems. Every car should have one!

Choosing a fan
There is usually more than one option when selecting the right fan for your car. Within limits, the bigger the engine, the bigger the fan required. And the bigger the fan, the better - you will always have cooling capacity in hand, and a larger fan will simply run for shorter periods. The limiting factors are the size of radiator core area available, the depth of the mounting space, and on older cars the ability of the car’s electrical system to provide the necessary current.

In general a single large fan is more efficient than two smaller ones, but  sometimes the shape of a car’s radiator means that two smaller fans fit in where a single, large fan won’t go!  If you want to fit two fans but there isn’t quite room, consider fit them on opposite sides of the radiator, with one fan pushing and the other pulling.

Other important factors are the state of tune of the engine, and your driving habits. If, for example, the car spends much of its time in slow moving traffic, or perhaps towing a caravan, then a larger size of fan might be called for.  

Why Davies Craig fans?

Davies Craig are an australian company, and the first (nearly 40 years ago) to develop electric fans to meet the demanding cooling needs of vehicles in australian summers.   Their extensive research has shown that a six-bladed fan with straight blades, and incorporating a patented blade tip design, gives the optimum combination of efficient air movement and low noise.  Various major motor manufacturers have fitted Davies Craig fans as original equipment over the years, mainly in the USA and Australia, due to their combination of excellent design, use of quality materials, and reliability and durability in service.

As well as selling in a wide range of sizes, from 8-inch to 16-inch blades, the fans have some unique and valuable features. They are totally reversible, so that the same fan can be fitted either in front of the radiator (“upstream” installation) or between the radiator and the engine (“downstream”). They are designed to be mounted flush against the radiator, so that virtually all the air shifted by the fan moves through the radiator, rather than spilling around it.   They are compatible with all electric fan controls, are suitable for both negative-earth and positive-earth systems, and come with a fixing kit including relay and wiring loom.  The manufacturers advise that the whole range of fans will run (at half speed) on 6-volt vehicles.   And, all Davies Craig fans are guaranteed for two years or 1500 hours use.
