You may experience several conditions in which the engine idle speed will be elevated above the base operating range. Conditions such as low battery voltage, PTO operation and cold engine warm-up will elevate the engine idle speed. All of these conditions noted above are NORMAL and do not require the vehicle to be taken to the dealership for diagnostic testing or service. Use the recommended CJ-4 engine oil in your 6.4L Power Stroke®®® engine. This engine oil has been designed to operate properly with the new emissions standards. If your vehicle is operated at high speeds while fully loaded, let the engine idle three to five minutes before shutting it off. This will allow the turbochargers to cool sufficiently and prevent the engine from overheating. A winter grille cover is now available as a Production option for Canadian customers and select cold weather U.S. states. The grille cover is also available at authorized Ford dealers for customers to purchase. The cover can be installed by the customer when heavy snow conditions exist. It must be removed at temperatures above 50˚F (10˚C) or above 32˚F (0˚C) when towing a trailer.

This will prevent cold weather start-up engine damage. A block heater must be used when temperatures are below -10˚F (-23˚C.) For conditions when the coolant temperature is below -10˚F (-23˚C), the Message Center will display a 30 second countdown timer. During this time, the engine will be limited to idle for a period of 30 seconds from engine start before normal operation can be continued. After this time has elapsed, a message "OK to Drive" will be displayed for five seconds. These messages are NORMAL.
