2011 Ram 5500 Chassis Cab radiator cap

Preparations for Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE:The positive battery post is covered with a
protective cap. Lift up on the cap to gain access to the
positive battery post.WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by
moving fan blades.
•Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories.

WHAT TO DO IN EMERGENCIES 371

To minimize the possibility of catalyst 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
idling or malfunctioning operating conditions.
Cooling System
WARNING!
You or others can be badly burned by hot coolant 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
is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
flushed and refilled with fresh coolant. Check the front of
the A/C condenser for any accumulation of bugs, leaves,
etc. If dirty, clean by gently spraying water from a garden
hose vertically down the face of the condenser.
396 MAINTAINING YOUR VEHICLE

Check the coolant recovery bottle tubing for brittle rub-
ber, cracking, tears, cuts and tightness of the connection
at the bottle and radiator. Inspect the entire system for
leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
If the cap is sealing properly, the engine coolant (anti-
freeze) will begin to drain from the coolant recovery
bottle. DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System – Drain, Flush and Refill
If the engine coolant (antifreeze) is dirty or contains a
considerable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of old engine coolant (antifreeze) solution.Refer to “Maintenance Schedule” for proper maintenance
intervals.
Selection Of Coolant
Use only the manufacturer’s recommended engine cool-
ant (antifreeze). Refer to “Fluids, Lubricants, and Genu-
ine Parts” in “Maintaining Your Vehicle” for further
information.
CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified HOAT engine coolant (antifreeze), may
result in engine damage and may decrease corro-
sion protection. If a non-HOAT engine coolant
(antifreeze) is introduced into the cooling system
in an emergency, it should be replaced with the
specified engine coolant (antifreeze) as soon as
possible.

MAINTAINING YOUR VEHICLE 397

Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:Mixing engine coolant (antifreeze) types will
decrease the life of the engine coolant (antifreeze) and
will require more frequent engine coolant (antifreeze)
changes.
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
recovery bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety pre-
caution. Never add engine coolant (antifreeze)
when the engine is overheated. 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
specified for your vehicle. Personal injury or en-
gine damage may result.

MAINTAINING YOUR VEHICLE 399

Disposal of Used 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 ani-
mals 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.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine cold, the level of the engine coolant (antifreeze) in
the coolant recovery bottle should be between the ranges
indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking forengine coolant (antifreeze) freeze point or replacing en-
gine coolant (antifreeze). Advise your service attendant
of this. As long as the engine operating temperature is
satisfactory, the coolant bottle need only be checked once
a month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Points to Remember
NOTE:
When the vehicle is stopped after a few miles (a
few kilometers) of operation, you may observe vapor
coming from the front of the engine compartment. This is
normally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot coolant to
enter the radiator.
