If The Engine Runs Hot; If Fuses Burn Out - Ford Diesel 2011 Supplement Manual

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

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.
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.
Refer to the Owner's Guide for replacement of fuses.
