Of course I'd completely forgotten that thread, Lars. AgentOrange really improved HIS mileage with the e-fan, didn't he? Same truck as mine too.

Looks like, according to my Haynes manual, that your 2006 had the viscous clutch fan too. Didn't you put in e-fans Lars? I know you replaced the pulleys. How has all this effected your mileage?

I guess the next time I'm at the dealership, I should go try to move a fan by hand to compare the resistance in the newer setup with mine. There's no doubt at all that there's significant, CONSTANT drag on the engine with my fan, regardless of the need for cooling.
