2004 CHRYSLER TOWN AND COUNTRY coolant temperature

12. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the engine is critically hot, a continuous
chime will sound for 4 minutes. After the chime
turns off, the engine will still be critically hot until the
light turns off.
13. Vehicle Theft Alarm Light Ð If Equipped
This light will flash for approximately 15 sec-
onds when the vehicle theft alarm is arming.
14. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads (H),
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the ªHº, and you hear continuous chimes, turn the
engine off immediately, and call for service.

Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE:In many temperature positions, the bi-level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Headliner Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vane knob on the outlets to
one side will shut off the air flow.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethyleneglycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
The air from the heater system will heat faster in cold
weather if you use only low blower speeds for the first 10
minutes of vehicle operation. Use of the air Recirculation
mode during winter months is not recommended be-
cause it may cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.

WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, fol-
low the preceding safety tips.
Cooling System
Inspection
WARNING!
²When working near the radiator cooling fan, turn
the ignition key to the OFF position. The fan is
temperature controlled and can start at any time
when the ignition key is in the ON position.
²You or others can be badly burned by hot 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 is hot.

Coolant Checks
Coolant protection checks should be made every 12
months (prior to the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant. Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty, clean by
removing the upper grill support and 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 coolant pressure cap for proper
vacuum sealing by draining a small amount of coolantfrom the radiator drain cock. If the cap is sealing prop-
erly, the coolant will begin to drain from the coolant
recovery bottle. DO NOT REMOVE THE COOLANT
PRESSURE CAP WHEN THE COOLING SYSTEM IS
HOT.
Cooling System Ð Drain, Flush and Refill
At the intervals shown in the maintenance schedules, the
system should be drained, flushed and refilled.
If the solution 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 old
antifreeze solution.
Selection Of Coolant
Use only the manufacturers recommended coolant, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct coolant type.

CAUTION!
Mixing of coolants other than specified (non-
HOAT), may result in engine damage that may not
be covered under the new vehicle warranty, and
decreased corrosion protection. If a non-HOAT cool-
ant is introduced into the cooling system in an
emergency, it should be replaced with the specified
coolant as soon as possible.
Do not use plain water alone or alcohol base anti-
freeze products. Do not use additional rust inhibi-
tors or antirust products, as they may not be compat-
ible with the radiator coolant and may plug the
radiator.
This vehicle has not been designed for use with
Propylene Glycol based coolants. Use of Propylene
Glycol based coolants is not recommended.
Adding Coolant
When adding coolant, or refilling the system, a minimum
of 50% solution of ethylene glycol antifreeze coolant in
water should be used. Higher concentrations (not to
exceed 70%) are required if temperatures below237ÉF
(238ÉC) are anticipated.
Use only high purity water such as distilled or deionized
water when mixing the water/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 coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.
328 MAINTAINING YOUR VEHICLE

operating temperature is satisfactory, the coolant recov-
ery bottle need only be checked once a month.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant recovery
bottle. Do not overfill.
Points to Remember
NOTE:When the vehicle is stopped after a few miles 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 accumulat-
ing on the radiator and being vaporized when the
thermostat opens, allowing hot water to enter the radia-
tor.
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.
²Do not overfill the coolant recovery bottle.
²Check coolant freeze point in the radiator and in the
coolant recovery bottle. If antifreeze needs to be
added, contents of coolant recovery bottle must also be
protected against freezing.
²If frequent coolant additions are required, or if the
level in the coolant recovery bottle does not drop when
the engine cools, the cooling system should be pres-
sure tested for leaks.
²Maintain coolant concentration at 50% ethylene glycol
antifreeze (minimum) in water for proper corrosion
protection of your engine which contains aluminum
components.
²Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
