2019 DODGE DURANGO cooling

•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 engine coolant
(antifreeze) will return to the radiator from the coolant
expansion bottle/recovery tank if so equipped.
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.

WARNING! (Continued)
•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 Coolant
Used ethylene glycol-based coolant (antifreeze) is a regu-
lated 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 coolant in open contain-
ers 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 OFF and cold, the level of the engine coolant
(antifreeze) in the bottle should be between the ranges
indicated on the bottle.

SERVICING AND MAINTENANCE 443

The radiator normally remains completely full, so there is
no need to remove the radiator/coolant pressure cap
unless checking for engine coolant (antifreeze) freeze point
or replacing coolant. 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, only OAT coolant that meets the
requirements of FCA Material Standard MS.90032 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 normally
a result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) 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 expansion bottle. •
Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.

CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine dam-
age and may decrease corrosion protection. Organic
Additive Technology (OAT) engine coolant is differ-
ent and should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant (anti-
freeze) or any “globally compatible” coolant (anti-
freeze). If a non-OAT engine coolant (antifreeze) is
introduced into the cooling system in an emergency,
the cooling system will need to be drained, flushed,
(Continued)
CAUTION! (Continued)
and refilled with fresh OAT coolant (conforming to
MS.90032), by an authorized dealer as soon as pos-
sible.
• Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (anti-
freeze) is not recommended.
