    I had these on 2 other trucks i had. They worked OK except in the summer in rush hour traffic. Eventually they would overheat, went back to stock fan clutches on both of them.
    Living in the south with it 90+ outside didn't help either

    personally i feel that a fan clutch is way more efficient and has less drag on the engine than running fans. the lack of a mechanical fan and the additional load to the electrical system is a bad trade off. i think you would be suprised at just how little HP is lost driving a fan clutch. the fact is the way the fluid coupled clutches work they literally almost freespin at anything above and idle. the only time this is not true is when the engine is first started untill the fluid in the clutch gets flung to the outer part of the clutch assembly.
    i considered installing electric but for the cost verses the bennifit which i think arguably is not much if any. you add a lot more likelyhood of fan failure going electric verses the trusty unit that came with your truck and will likely last the lifetime of the vehicle without any problems.
    if you want to get technical i would imagine electric fans actually add weight over the stock fan

    I've read articles in a diesel mag where they installed electric fans on a Cummins, it increased fuel economy by 1-2 mpg. However flex-a-lite does not recommend pulling heavy loads with their electric fans on a Cummins. Many car companies use electric fans, many use a combination of electric and mechanical, I think a combination would be the best.
