Cooling System
WARNING!
You or others can be badly burned by hot antifreeze/
coolant or steam from your radiator. If you see or
hear steam coming from under the hood, don’t open
the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Engine Coolant Checks
Check antifreeze/coolant protection every 12 months
(before the onset of freezing weather, where applicable).
If antifreeze/coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
antifreeze/coolant. Check the front of the A/C condenser
(if equipped) or radiator for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a
garden hose vertically down the face of the A/C con-
denser (if equipped) or the radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks.
Cooling System — Drain, Flush, And Refill
At the intervals shown on the appropriate “Maintenance
Schedule” the system should be drained, flushed, and
refilled.
If the coolant solution is dirty or contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner (see your authorized dealer for
recommendations). Follow with a thorough rinsing to
remove all deposits and chemicals. Properly dispose of
old antifreeze/coolant solution.
332 MAINTAINING YOUR VEHICLE

Adding Engine Coolant
Your vehicle has been built with an improved antifreeze/
coolant that allows extended maintenance intervals. This
antifreeze/coolant can be used up to 5 Years or 100,000
miles before replacement. To prevent reducing this ex-
tended maintenance period, it is important that you use
the same antifreeze/coolant throughout the life of your
vehicle. Please review these recommendations for using
Hybrid Organic Additive Technology (HOAT) coolant.
When adding antifreeze/coolant, a minimum solution of
50% recommended Mopar Antifreeze/Coolant 5 Year/
100,000 Mile Formula HOAT (Hybrid Organic Additive
Technology), or equivalent, in water should be used. Use
higher concentrations (not to exceed 70%) if temperatures
below -34°F (-37°C) are anticipated. Use only high purity water such as distilled or deionized
water when mixing the water/antifreeze (coolant) solu-
tion. 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 antifreeze/coolant types will decrease
the life of the antifreeze/coolant and will require more
frequent antifreeze/coolant changes.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
antifreeze/coolant, and to insure that antifreeze/coolant
will return to the radiator from the coolant recovery
bottle.
334 MAINTAINING YOUR VEHICLE

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 precaution.
Never add antifreeze/coolant 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.
Disposal of Used Engine Coolant
Used Hybrid Organic Additive Technology (HOAT)
antifreeze/coolant 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
HOAT antifreeze/coolant in open containers, or allow it
to remain in puddles on the ground. If ingested by a
child, contact a physician immediately. Clean up ground
spills immediately.
Engine Coolant Level
The coolant recovery bottle provides a quick visual
method for determining that the antifreeze/coolant level
is adequate. With the engine idling, and warm to normal
operating temperature, the level of the antifreeze/coolant
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 for
antifreeze/coolant freeze point or replacing coolant. Ad-
vise your service attendant of this. As long as the engine
operating temperature is satisfactory, the coolant bottle
need only be checked once a month.
