Hello, I have a 2008 Dodge Ram Bighorn with the 5.7 HEMI. I have recently noticed that when I start my truck the cooling fan seems to be louder than normal. It seems to go quite again if I leave it run awhile or drive a block or two. Almost reminds me of the howl of a diesel engine. Anyone have any idea what this is?

 

That's normal. It's the clutch fan. Older cars when the choke was engaged were no different.

 

Yep. clutch fan... normal.. You can fix it with an E-fan though

 

I 3rd that. My 08 has done it from day one. It takes a little bit for the clutch fluid to disperse thru the clutch after sitting for a while.
