    These is a couple of threads on engine noise from the mechanical cooling fan. I think it's nuts that Toyota put a this in a 2014 vehicle. All about $ I would think , maybe its a reliability thing in extreme environments. Who knows , but I would love to get rid of that roar at start up.

    Hey Dave, :)

    I'm also intrigued by that fan kit. My 2012 Toyota Yaris has electric cooling and it works great. I don't think anyone here has actually tried one on their 2.7, or even a 4.0 for that matter. But maybe someone has and can let us know how it works.

    Thanks for the reply's. I was thinking the other day I have an old flex a lite 2800cfm kit in my garage. I might pull in off the shelf and see what it looks like and if I can adapt it to fit. I know its a little smaller than the kit sold specifically for the truck, But as long as I can get 80% coverage I think I would be OK. I would need to build a bracket for the overfow tank too. Save myself some cash over buying the new kit. I don't care for the roar, and I know it would help out on economy and free up power. I'm OK with the power now, but I occasionally tow about 1200lbs with it and I think that is were it would really be nice.

    It's still common in the industry to use clutch fans for longitudinally-mounted engines. There is a temperature-controlled fan clutch, so parasitic losses are low. In addition to modern pickups, here's an example of a modern Audi with clutch fan:

    The only real drawback to the clutch fan is less optimal A/C performance at idle. The Audi pictured has a separate condenser fan for this reason.
