Freightliner FRED Electric fans.

Has anyone installed or had installed electric fans to their 6.7 Cummins ISB 340 HP front engine diesel? Looking for a source or any helpful info. I have a 2008 Tiffin 35 TSB with 6.7 ISB. Fan clutch is extremely noisy. John You can call me or e mail me. 404-909-4883. I live in the Atlanta area. Thanks.

Perhaps you should invest in more sound deadening instead of changing to electric fans? Just a thought.

We have a 2009 Newmar FRED on a Freightliner chassis with a 340 Cummins ISB engine. Just had to put on a new turbocharger and since then I have noticed a different behavior in when that loud cooling fan comes on and off. My gauge doesnt have many numbers but my guess is the fan kicks on about 180 degrees and the temp never gets much over 200. That was about what it did before the new turbo...but the new wrinkle is that it stays on longer, even when the temp is way down to that "about" 180 area. It sure sucks power and the engine sounds great and has great power if I could just get rid of that cooling fan staying on so long....agree on the sound dampening idea too
