Introduction
Cars have used on-demand electric radiator fans for decades, but some trucks still have less efficient, belt-driven ones.
Aftermarket kits are available for many models, or you can retrofit a junkyard electric cooling fan from another vehicle.

Problems / Consequences of mod
Electric fans normally do not have the air moving power of a belt driven fan. To many or too much electric fan can drain power from the electrical system and may require an alternator up grade if you have to run the fans a lot. Engine cranks over faster, runs quieter with out the belt driven fan beating air all the time and the engine warms up 2 to 3 minutes faster for me. When running 2 or 3 electric fans on a car or truck you dont have one single point of failure such as the thermal clutch.
