engine overheat Ram 3500 Chassis Cab 2017 User Guide

Towing Tips
Before setting out on a trip, practice turning, stopping and
backing the trailer up in an area away from heavy traffic.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent shift-
ing does occur while in DRIVE, select TOW/HAUL mode
or select a lower gear range (using the Electronic Range
Select (ERS) shift control).
NOTE:Using TOW/HAUL mode, or selecting a lower
gear range (using the ERS shift control) while operating the
vehicle under heavy loading conditions will improve per-
formance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
When towing a loaded trailer up steep grades at low
speeds (20 mph [32 km/h] or below), holding your vehicle
in first gear (using the ERS shift control) can help to avoid
transmission overheating. If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the transmission fluid
and filter(s) as specified for
police, taxi, fleet, or frequent
trailer towing. Refer to the “Maintenance Schedule” for
the proper maintenance intervals.
NOTE: Check the automatic transmission fluid level be-
fore towing.
Tow/Haul Mode
To reduce potential for automatic transmission overheat-
ing, activate TOW/HAUL mode when driving in hilly
areas, or select a lower gear range (using the Electronic
Range Select (ERS) shift control) on more severe grades.
Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
420 STARTING AND OPERATING

Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
When stopped for short periods of time, shift the transmis-
sion into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
SNOWPLOW
Snowplow Prep Packages are available as a factory in-
stalled option. These packages include components neces-
sary to equip your vehicle with a snowplow.
NOTE:Before installation of a snowplow it is highly
recommended that the owner/installer obtain and follow
the recommendations contained within the current Ram
Body Builders Guide. See your authorized dealer, installer
or snowplow manufacturer for this information. There are unique electrical systems that must be connected to prop-
erly assure operator safety and prevent overloading ve-
hicle systems.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.
Do not expect that the airbag will perform as described
earlier in this manual.
CAUTION!
The “Lamp Out” indicator could illuminate if exterior
lamps are not properly installed.
Before Plowing
•
Check the hydraulic system for leaks and proper fluid
level.
• Check the mounting bolts and nuts for proper tightness.
• Check the runners and cutting edge for excessive wear.
The cutting edge should be ¼ to ½ in (6 cm to 1.2 cm)
above ground in snow plowing position.
• Check that snowplow lighting is connected and func-
tioning properly.

STARTING AND OPERATING 421

General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer’s instructions.
Keep all snowplow electrical connections and battery ter-
minals clean and free of corrosion.
When plowing snow, to avoid transmission and drivetrain
damage, the following precautions should be observed.
•Operate with transfer case in 4LO when plowing small
or congested areas where speeds are not likely to exceed
15 mph (24 km/h). At higher speeds operate in 4HI. •
Vehicles with automatic transmissions should use 4LO
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
• Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal while shifting the
transmission.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the upper
switch bank just below the radio.Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming traffic
of an emergency. Push the switch a second time to turn off
the Hazard Warning flashers.
This is an emergency warning system and it should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down. •
In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
430 WHAT TO DO IN EMERGENCIES

CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of clutch or transmission failure during prolonged
efforts to free a stuck vehicle.
NOTE: Push the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode, before
rocking the vehicle. Refer to “Electronic Brake Control
System” in “Starting And Operating” for further informa-
tion. Once the vehicle has been freed, push the ESC Off
switch again to restore ESC Onmode.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
(Continued)
WARNING! (Continued)
stuck and do not let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
•When “rocking” a stuck vehicle by shifting between
DRIVE/SECOND GEAR and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
EMERGENCY TOW HOOKS — IF EQUIPPED
Your vehicle may be equipped with emergency tow hooks.
NOTE: For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of damage
to the vehicle.
444 WHAT TO DO IN EMERGENCIES

CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
• Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE: Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you. In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
•
Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.

476 MAINTAINING YOUR VEHICLE

NOTE:
•It is the owner’s responsibility to maintain the proper
level of protection against freezing according to the
temperatures occurring in the area where the vehicle is
operated.
• Some vehicles require special tools to add coolant prop-
erly. Failure to fill these systems properly could lead to
severe internal engine damage. If any coolant is needed
to be added to the system, please contact your local
authorized dealer.
• Mixing engine coolant (antifreeze) types is not recom-
mended and can result in cooling system damage. If
HOAT and OAT coolant are mixed in an emergency,
have a authorized dealer drain, flush, and refill with
OAT coolant (conforming to MS.90032) as soon as pos-
sible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that the engine coolant
(antifreeze) will return to the radiator from the coolant
expansion bottle. The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•
Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap to cool an
overheated engine. Heat causes pressure to build up
in the cooling system. To prevent scalding or injury,
do not remove the pressure cap while the system is
hot or under pressure.
• Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or engine
damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is a
regulated substance requiring proper disposal. Check with
your local authorities to determine the disposal rules for
your community. To prevent ingestion by animals or
children, do not store ethylene glycol-based engine coolant
(antifreeze) in open containers or allow it to remain in
puddles on the ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up any ground
spills immediately.
