Hello. Here are the results. I see about 1-1.5 mpg gain measured at the pump. What kills our mileage is sitting in traffic or a drive through. With that said, sitting through a normal week of backups I am seeing a gain of 1-1.5 mpg when I fill up. This will surely pay for itself. I am out about 70 bucks in total. I have my fan wired to run soley on the thermostat so when I shut down the fan stays on for a couple minutes to help cool the engine quicker.

Let me know if anyone has any questions.

What kind of efan have most of you been using??? The Taurus, Mark VIII, etc. Ive seen the flex-a-light xtreme 180 e fan but, 300 bucks!? Im not going to heavily modify my 07 QC 4x4 but I would like to squeeze the most power that I can without breaking the bank.

Awesome...looks like it bolted up real easy. Im gonna give a couple of junk yards a call to see if they have any available. Also, how do you have it wired up since the mark VIII fans are 2 speeds. Id like to have it wired were it comes on at a certain temp compared to me having to pay attention to the temp of the engine. I have a jet 180 tstat installed already so I know that will help out with the temp even more and will the E Fan and T Stat work well enough as they are instead of getting a programmer and adjusting the settings????
