I about to take my new truck into the dealer for its first service (about 3500 miles). I am only going to use the dealer for warranty work and work I can not do myself. I can certainly do an oil change, as soon as I get a larger drain bucket. The only problem I've had with my truck is the fan clutch is sticking on. Sometimes I'll start it in the morning and the fan clutch is stuck engaged, and stays that way until I stop for a while, and restart. It's pretty noisy and irritating, especially when you don't need it. Has anyone else had this problem with their 6.0? I'm wondering if it is a widespread problem. I've not seen a TSB on this. Later
