heater Ram 2500 (Diesel) 2007 User Guide

•Voltmeter Operation:
•The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation
is caused by the post-heat cycle of the intake mani-
fold heater system. The number of cycles and the
length of the cycling operation is controlled by the
engine control module. Post-heat operation can run
for several minutes, and then the electrical system
and voltmeter needle will stabilize.
•The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.
Cold Weather Precautions
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts sug-
gest these options:
Fuel Operating Range (5.9L Diesel Engine)
*No. 1 diesel fuel should only be used where extended
arctic conditions (-10°F/-23°C) exist.
NOTE:
•Use of Climatized Diesel Fuel or Number 1 Diesel Fuel
results in a noticeable decrease in fuel economy.
282 STARTING AND OPERATING

•Climatized Diesel Fuel is a blend of Number 2 and
Number 1 Diesel Fuels which reduces the temperature
at which wax crystals form in fuel.
NOTE:Refer to Fuel Requirements in this section for
further details on fuel recommendations.
Fuel Operating Range (6.7L Diesel Engine)
NOTE:Use “Ultra Low Sulfur Diesel Fuels”ONLY.
*No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F/-23°C) exist.NOTE:
•Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
•Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.
NOTE:The engine requires the use of“Ultra Low
Sulfur Diesel Fuel”. Use of incorrect fuel could result in
engine and exhaust system damage. Refer to Fuel Re-
quirements in this section for further details on fuel
recommendations.
Engine Block Heater
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the heater
STARTING AND OPERATING 283

cord to a ground–fault interrupter protected 110–115 volt
AC electrical outlet with a grounded, three-wire exten-
sion cord.
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.
NOTE:The engine block heater cord is a factory in-
stalled option. If your vehicle is not equipped, heater
cords are available from your authorized Mopardealer.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110–115 volt electrical cord could
cause electrocution.NOTE:The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
Block Heater Usage
A.Temperatures below 0°F (-18°C)
•Block Heater Required for 15W-40
•Block Heater Recommended for 5W-40
B.Temperatures below - 20°F (-29°C)
•Block Heater Required for 5W-40
Winter Front Usage
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 per-
centage 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

JUMP-STARTING
WARNING!
To prevent personal injury or damage to clothing, do
not allow battery fluid to contact eyes, skin or fabrics.
Do not lean over a battery when connecting jumper
cables or allow cable clamps to touch each other.
Keep open flames or sparks away from battery vent
holes. Always wear eye protection when working
with batteries.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. do
not use a 24 volt power source.NOTE:Replacement batteries should both be of equal
size to prevent damage to the vehicles charging system.
Your vehicle is equipped with two 12–volt batteries. If it
becomes necessary to use a booster battery, with jumper
cables, to start a vehicle’s engine because its batteries are
discharged, the following procedure should be followed:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If indica-
tor (if equipped) is light or yellow on either battery,
replace that battery.
