2020 DODGE GRAND CARAVAN radiator

SERVICING AND MAINTENANCE241
To prevent reducing this extended maintenance
period, it is important that you use the same
engine coolant (OAT coolant conforming to
MS.90032) throughout the life of your vehicle.
Please review these recommendations for
using Organic Additive Technology (OAT) engine
coolant (antifreeze) that meets the
requirements of FCA Material Standard
MS.90032. When adding engine coolant
(antifreeze):
We recommend using Mopar
Antifreeze/Coolant 10 Year/150,000 Mile
(240,000 km) Formula OAT (Organic Additive
Technology) that meets the requirements of
FCA Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of FCA
Material Standard MS.90032 and distilled
water. Use higher concentrations (not to
exceed 70%) if temperatures below −34°F
(−37°C) are anticipated. Please contact an
authorized dealer for assistance.
Use only high purity water such as distilled or
deionized 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.
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 properly. 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 a local autho -
rized dealer.
Mixing engine coolant (antifreeze) types is
not recommended 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
possible.
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 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 engine damage may result.

242SERVICING AND MAINTENANCE
Disposal Of Used Coolant
Used ethylene glycol-based 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
coolant 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.
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 (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 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) addi-
tions are required, the cooling system should
be pressure tested for leaks.
Maintain engine coolant (antifreeze) concen
-
tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled
water for proper corrosion protection of your
engine which contains aluminum
components.
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 ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.
Brake System
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.

CAUTION!
Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may
result in engine damage and may decrease
corrosion protection. Organic Additive Tech -
nology (OAT) engine coolant is different and
should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant
(antifreeze) or any “globally compatible”
coolant (antifreeze). 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, and refilled with fresh OAT coolant
(conforming to MS.90032), by an autho -
rized dealer as soon as possible.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.
CAUTION! (Continued)
This vehicle has not been designed for use
with propylene glycol-based engine coolant
(antifreeze). Use of propylene glycol-based
engine coolant (antifreeze) is not
recommended.
CAUTION! (Continued)
