diesel engine. However, if seasonably adjusted fuel is
not available and you are operating below 20°F (-6°C),
Mopar® Premium Diesel Fuel Treatment (or equiva-
lent) may be beneficial to avoid fuel gelling.
Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for the correct engine oil viscosity.
Winter Front Usage
A winter front or cold weather cover is to be used in
ambient temperatures below 32°F (0°C), especially dur-
ing extended idle conditions to reduce condensation
build-up within engine crankcase. If a winter front or
cold weather cover is to be used, a percentage of the total
grille opening area must be left uncovered to provide
sufficient air flow to the charge air cooler and automatic
transmission oil cooler. The percentage of opening must
be increased with the increasing ambient air temperature
and/or engine load. If the cooling fan can be heard
cycling frequently, increase the size of the opening in the
winter front. A suitable cold weather cover is available
from your MOPAR® dealer.
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°C). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized MOPAR® dealer.
Engine Warm-Up
Avoid full throttle operation when the engine is cold.
When starting a cold engine, bring the engine up to
operating speed slowly to allow the oil pressure to
stabilize as the engine warms up.
