2010 DODGE CHARGER SRT cooling

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!
•When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the LOCK position. The fan is tempera-
ture controlled and can start at any time the
ignition switch is in the ON position.
•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 is hot.

Coolant Checks
Check 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 engine coolant (anti-
freeze). 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.
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 the old engine coolant (antifreeze) solution.
Refer to “Maintenance Schedule” for further information.
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.7

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.
•Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the radiator engine
coolant (antifreeze) and may plug the radiator.(Continued)
CAUTION! (Continued)
•This vehicle has not been designed for use with
propylene glycol-based engine coolant (anti-
freeze). Use of propylene glycol-based engine
coolant (antifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (antifreeze) coolant that allows extended mainte-
nance intervals. This engine coolant (antifreeze) can be
used up to five years or 102,000 miles (170 000 km) before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same
engine coolant (antifreeze) throughout the life of your
vehicle. Please review these recommendations for using
Hybrid Organic Additive Technology (HOAT) engine
coolant (antifreeze).
350 MAINTAINING YOUR VEHICLE

When adding engine coolant (antifreeze):
•The manufacturer recommends using MOPAR
Antifreeze/Coolant 5 Year/100,000 Mile Formula
HOAT (Hybrid Organic Additive Technology) or
equivalent.
•Mix a minimum solution of 50% HOAT engine coolant
(antifreeze) and distilled water. Use higher concentra-
tions (not to exceed 70%) if temperatures below34°F
(37°C) are anticipated.
•Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
engine cooling system. 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 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.
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 disposalrules 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 engine coolant (antifreeze) level is
adequate. With the engine OFF and cold, the level of the
engine coolant (antifreeze) in the bottle should be be-
tween the ranges indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
engine coolant (antifreeze) freeze point or replacing en-
gine coolant (antifreeze). Advise your service attendant
352 MAINTAINING YOUR VEHICLE

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
(kilometers) of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant recovery bottle.
•Check engine coolant (antifreeze) freeze point in the
radiator and in the coolant recovery bottle. If engine
coolant (antifreeze) needs to be added, contents of
coolant recovery bottle must also be protected against
freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine, which contains aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
