In your post you mentioned "coming down from the Divide" Just curios where you live? Also is your truck 2 wheel or 4 wheel drive?
And why did you not re install the fan shroud? Wouldn't it help guide Air to the hot parts of the engine vs. just drifting up and all around? I want to do the electro fan conversion but hesitate to just start tearing into my truck.
Thanks

Sorry this took a while, I've been out playing.
It's been a great summer for rafting!
Over the divide for me is typically I-70 from Aurora, and then either branching off on 9 towards the 'boat, at Rifle towards Vernal, or on past Junction. My truck is 2wd and stick - not many like it out there, honestly - which coupled with the scan guage lets me engine brake until the gas starts flowing again, and then just coast with the engine on. For some reason hills like the tunnel down to Silverthorne seem to be too long to have no-fuel engine braking the whole way. 70 mgp isn't nearly as much fun as 9999.
The fan shroud wouldn't have fit over the electric fans, and they sit flush to the radiator anyway. I might lose a little direct airflow cooling over the engine block, but I don't think very much by the time it's all said and done.
As for ripping into the truck, I could pull the electric fans off and put the factory fan and shroud back, and no one would ever be the wiser. Part of why I was willing to do it...
