The 6.0L diesel is still having some issues with the EGR valves clogging up. Part of the problem is extended idle time without the high idle set. This is a friendly reminder that anytime the truck is at idle the high idle MUST be set!! Ford is also looking at fuel additives to help but the simplest thing to do is use the high idle. The easiest way to know if you are in a 6.0L is that they have a tachometer (rpm’s) next to the speedometer. When in doubt, set the high idle! If you don’t know how, all you do is set the parking brake! Helpful tip, this also let’s the air conditioner cool better in the hot weather!!!
