Winter grille cover (F-Super Duty only) (if equipped)
If your vehicle includes a winter grille cover, it will enhance heater
performance and will reduce the amount of time it takes to warm the
inside of your vehicle in extremely cold conditions (below 0°F [-18°C]).
The winter grille cover installs over the outside of the grille of your
vehicle and restricts the air flowing to the engine compartment by
covering the radiator grille openings.
Usage guidelines
The winter grille cover should only be used while operating your vehicle
in extremely cold temperatures or in heavy snow for extended periods of
time. In these temperatures, the vehicle does not need a large amount of
air to properly cool the engine. During periods of operation when more
airflow is required to cool the vehicle, the winter grille cover should not
be used. The following usage guidelines will allow adequate airflow for
proper radiator and air cooler performance.
•
Do not use the winter grille cover when temperatures are above 50°F
(10°C). Use of the cover in these conditions could cause your vehicle
to overheat. If this happens while the cover is being used, remove the
cover and store properly.
•
Do not use the winter grille cover above 32°F (0°C) if towing a trailer.
The added power needed to tow a trailer requires the radiator grille to
have full airflow under all conditions. Your vehicle may overheat if the
cover is used while towing a trailer.
•
Do not modify the winter grille cover. The winter grille cover does not
block some sections of the front of the vehicle because these openings
are needed to provide enough airflow to the radiator and air cooler in
extremely cold temperatures.
