“I’ve always had an inquisitive mind, you know? I’ve always taken things apart since I was little, so I could see how they worked, but then also so I could put them back together and make them work even better than they ever had. That’s what got me started with building cars; that’s what got me to open this little hot rod shop. I’ve learned to apply that line of thinking to all of life, and I’d like to think that’s made me a better creator, a better visionary, and a better human because of it.”

Here it is! The easy drop in solution to the failure prone mechanical factory fan you’ve been waiting for!

Anyone who has owned a BMW from this era knows quite well of the issues involving the factory fans. From the difficulty of removing them from the engine, the power they rob, and their inevitable failures, they oftentimes result in unannounced explosion of fan blades at speed! No more! I’ve worked to put together a simple-to-install kit for electric fan conversion, including the fan, shroud, temperature sensor, wiring harness, and directions! Everything you need to convert an E39 540i to electric fan is included in this, and it is all pre-assembled!

What you get:

Spal 16” fan, 2024 cfm, with two pin weatherpack connector installed

New factory radiator shroud with aluminum fan adapter plate installed (all hardware is stainless steel)

Wiring harness with connectors and fan relay

Coolant temperature sensor

Radiator hose insert for coolant temperature sensor with hose clamps

Clear directions with photos

What this achieves:

Quiet dependability with an electric Spal fan, the best in the industry

Factory appearance while upgrading to a more problem free solution

Horsepower freed up with the deletion of the mechanical fan

No more worry to when your factory plastic mechanical fan will fail (and they do almost always fail)

Don’t wait for your factory fan to come apart and take out your radiator, coolant hoses, and more! Pick up one of these fan kits today!
