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, the
system should be drained, flushed, and refilled with
fresh OAT coolant (conforming to MS-12106) by an
authorized dealer. 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 engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at
the coolant recovery 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
NOTE: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 your
local authorized dealer.
If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (antifreeze) (conforming to MS-
12106).
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.

Selection Of Coolant
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine
damage and may decrease corrosion protection.
Organic Additive Technology (OAT) engine cool-
ant is different and should not be mixed with
Hybrid Organic Additive Technology (HOAT) en-
gine coolant (antifreeze) or any “globally compat-
ible” 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
(Continued)
CAUTION!(Continued)
OAT coolant (conforming to MS-12106), by an
authorized 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.
•This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (an-
tifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS-12106) that
allows extended maintenance intervals. This engine cool-
ant (antifreeze) can be used up to ten years or 150,000
688 MAINTAINING YOUR VEHICLE

•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-12106) 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
recovery tank.
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 en-
gine 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 ani-
mals or children, do not store ethylene glycol-based
engine 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.
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.
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 Chrysler Material Standard MS-
12106 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.

MAINTAINING YOUR VEHICLE 691

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 (anti-
freeze) needs to be added, the contents of the coolant
expansion bottle must also be protected against freez-
ing.
•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-
12106) and distilled water for proper corrosion protec-
tion of your engine which contains aluminum compo-
nents.
•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 emis-
sions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
