Is this noise normal?

[eddingsj]

2005 F-350 6.0 - New to diesels and trying to learn where I can. I have a question about a noise I heard while towing my trailer uphill. I was towing my 4 place snowmobile trailer up a grade, not pushing the truck whatsoever, just taking it nice and easy. All of a sudden the engine noise changed to like someone turned a huge fan on. There was no change in the truck's performance and the noise went away after I crested the hill. Engine temperature jumped up about 10-15 degrss from where it normally sits ( around 180 degress). EGTS went up, but not to much, maybe around 850 -900.

Is that the turbo making that noise? Engine fan? Seemed awful loud for the engine fan.

Another question: What is considered normal vs. high vs. dangerous EGT's. Me EDGE programmer warns me at about 1200.

Thanks -Jeff

Just your fan clutch engaging the cooling fan. It makes a he!! of a racket, moves a lot of air. Nothing to worry about

HeHeHe... kinda get's you that first time doesn't it? Sure did me. I was heading over the mountains in CO the first time and I almost pulled over . Reasoned that it must be a cooler fan due to the strain. I was still antsy about it until I got where I could research for sure.

Most guys will tell you that 1200-1250* is fine for egts, 1300-1350 is a high, but nothing to really worry about for short periods, i personally wouldnt want to see my gauge go over 1350 for an extended period, but in the 1/4 its fine.
