I'm not talking about the noise of rushing air because these fans move some serious amounts of air. I'm talking about strange noises like the aux. fan is about to dislodge. This problem is becoming very common (according to my service department) after the trucks get a few miles on them. This problem is not limited to the Titan, it's VERY common on the Armada as well...go figure..
Anyhow, the Aux. fan is only held on with one screw at the very top of the housing, the bottom is held in by two posts at the bottom of the fan housing that slide down into the plastic frame that also holds the radiator and condensor. Over time these bottom mounts get loose and that's when the weird noises start.
To check if your aux. fan is loose, first turn the vehicle off, reach into the lower grill opening and grab the fan housing. If the bottom moves side to side or fore and aft than it's loose.
Here's some pictures I took of this mod of which only takes about 30 minutes to do. If the pics aren't big enough just go to my pic site and the full size pics will be there.
Have Fun and let me know if this mod helps anyone else out there in Titan land!!
