Engine Block Heater
For ambient temperatures below 0°F (-18°C), engine block heater usage is recommended.
For ambient temperatures below –20°F (-29°C), engine block heater usage is required.
The engine block heater cord is routed under the hood to the right side and can be
located just behind the grille near the headlamp.
Connect the heater cord to a ground-fault interrupter protected 110–115 volt AC
electrical outlet with a grounded, three-wire extension cord.
NOTE:
The block heater will require 110 volts AC and 6.5 amps to activate the heater
element.
The block heater must be plugged in at least one hour to have an adequate warming
effect on the coolant.
Water In Fuel Message
If a Water In Fuel message or
indicator appears in the cluster and a chime
sounds five times, the fuel/water separator will need to be drained immediately to
prevent engine damage.
Refer to “Draining Fuel Water Separator” in this guide for draining instructions or see
your dealer.
Cold Start Procedure
Turn the ignition switch to the ON position. If the Wait To Start
light appears in
the cluster, wait for the light to turn off before starting.
In extremely cold weather below 0°F (-18°C) it may be beneficial to cycle the
manifold heaters twice before attempting to start the engine. This can be accom-
plished by turning the ignition OFF for at least five seconds and then back ON after
the “Wait To Start Light” has turned off, but before the engine is started. However,
excessive cycling of the manifold heaters will result in damage to the heater elements
or reduced battery voltage.
Refer to the Diesel Supplement at www.ramtrucks.com/en/owners/manuals for fur-
ther details.
Winter Front Cover Usage
A winter front or cold weather cover is to be used in ambient temperatures below
32°F (0°C), especially during extended idle conditions. This cover is equipped with
four flaps for managing total grille opening in varying ambient temperatures. If a
winter front or cold weather cover is to be used the flaps should be left in the full open
position to allow air flow to the charge air cooler and automatic transmission oil
cooler. When ambient temperatures drop below 0°F (-17°C) the four flaps need to be
closed. A suitable cold weather cover is available from your Mopar dealer.
