Yesterday, I drove to work 7 miles (morning) and back 7 miles(evening). clutch fan never disengaged. this morning, on the way to work, clutch fan still on. the dealership is right next door to my work. So i decided to pull in so i can show them. The service advisor called the head mechanic that works on the RAMS. When I revved the engine, the truck roared. he said it sounds perfectly normal.
I asked him for a test drive. he said sure. as soon as we pull out of the dealership, the clutch fan disengages. He then explains to me that the clutch fan uses oil and works like a hydrolics. He said the clutch isn't electric or mechanical.
He said the clutch engages and disengages at certain temps even when at cold start. Just the way this clutch fan is designed to work. He said you want the clutch fan to run, when it doesn't run, that's when cars over heat.
He even offered to replace the clutch fan with a new one. he said "i'll guarantee it is going to do the same exact thing."
When I do normal driving, you won't really notice the clutch fan roar. it's when I drive it hard it really roars.
