We went ahead and pulled the trigger on the truck.....
Yea this noise seems highly odd... Today we went and signed all the papers. It is approx 40 miles to the dealer..
The temp gauge never went too 200 degrees....
After driving around 10 minutes I could start to hear it fire off on the highway and was consistent.. Really annoying when accelerating.
Around the thirty minute mark we pulled off for some breakfast. After truck sitting for approx 1.5 hours, the fan was still very loud once started.
Before we headed out I pulled to hood and had the wife workin throttle. I just wanted to verify that the noise was in fact from the fan area..
I had the hood up, and I was standing next to the mirror drivers side telling the wife how much throttle to give it. She kicked it up to (guessing here) 2500 RPM and it damn near blew my hat off.. I was by the mirror looking into the cab at this time.. This think has some airflow!!!! Just seems little much to me after sitting for so long.. Noise is definitely the fan..
Little more info
Ambient temp around 75
Did not drive truck real hard, just hard enough to enjoy the fact that now I can gain speed, uphill, without vehicle downshifting..... :drool2:
Disclaimer.... "Hill" = overpass..
