Roaring fan noise

[kcnizdodge]

Ok, gentlemen, here is my problem. Sometimes when my truck gets warmed up, it sounds like I have this bodaciously huge fan running under the hood. I don't know if the fan clutch is engaged, but the engine is not overly warm, usually under 200*. It doesn't happen all the time. I can't for the life of me figure out what it is. Anyone have any ideas or had this same problem?



Thanks

Normal

Do a seach on here and you will find that it is normal.

The clutch is engaging the fan. Or the fan is engaging the clutch. They're married now. That's a joke.



Perfectly normal sound, loud hurricane type wind sounds... it's all good.

The time to worry is when you're dragging a heavy 5th wheel up a 6% grade on a 100 degF day, the coolant temperature gauge starts heading to the right, and you DON'T hear that noise!! :{ :{

Thank you gentlemen! I appreciate your letting me know there isn't a problem with my truck. Now I can go on vacation and relax, knowing everything is cool with the truck!!

Now reflecting back I think the fan will cycle with the air conditioner, defroster,or if it gets warm temps. try turning the selector to pannel or floor position. I believe this will quiet things down
