Maintenance If the engine runs hot The following could cause the engine to overheat: • Lack of coolant. • Dirty cooling system. • Plugged radiator fins, A/C condenser and/or oil cooler. • Malfunctioning fan drive. • Driving with frozen coolant. • Sticking thermostat. • Overloading or pulling heavy trailers during hot weather. • Grill or radiator air blockage. • Slipping or missing drive belt. • Plugged or very dirty air filter. If fuses burn out WARNING: Replacement fuses and circuit breakers must always be the same rating as the original equipment shown. Never replace a fuse or circuit breaker with one of a higher rating. Higher rated fuses or circuit breakers could allow circuit overloading in the event of a circuit malfunction, resulting in severe vehicle damage or personal injury due to fire. Burned-out or blown fuses usually indicate an electrical short-circuit, although a fuse may occasionally burn out from vibration. Insert a second fuse. If this fuse immediately burns out and you cannot locate the cause, return your vehicle to your dealer for a circuit check. Refer to the Owner's Manual for replacement of fuses. Selective catalytic reduction (SCR) system speed limit and Idle-only modes If the vehicle's speed is limited or in an idle-only mode, the SCR system may be limiting the vehicle's functions due to low or contaminated diesel exhaust fluid (DEF). Check the DEF. See Selective catalytic reduction (SCR) system in the Fuel and Refueling chapter for more information. 63 2013 Diesel (67l) Supplement, 1st Printing USA (fus)
