cooling CHRYSLER PT CRUISER 2008 1.G Owners Manual

If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.
WARNING!
If you are required to drive with the deck lid/liftgate
open, make sure that all windows are closed, and the
climate control blower switch is set at high speed.
DO NOT use the recirculation mode.Safety Checks You Should Make Inside The
Vehicle
Seat BeltsInspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (bent retractor, torn
webbing, etc. If there is any question regarding belt or
retractor condition, replace the belt.
Airbag LightThe light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the LED is not lit during starting, have it
checked. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.DefrosterCheck operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield.
116 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

INSTRUMENT CLUSTER DESCRIPTIONS1. Fuel GaugeWhen the ignition switch is in the ON position, the
pointer will show the level of fuel remaining in the
fuel tank.
2. Fuel Door Reminder
This is a reminder that the Fuel Filler Door is located on
the front passenger’s (right) side of the vehicle.
3. Temperature Gauge The temperature gauge shows engine coolant tem-
perature. Any reading below the red area of the
gauge shows that the engine cooling system is
operating properly. The gauge pointer may show a
higher than normal temperature when driving in hot
weather, up mountain grades, in heavy stop and go
traffic, or when towing a trailer. If the pointer rises to the
H(red) mark, the instrument
cluster will sound a chime. 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 H(red) mark, turn the engine off
immediately and call for service.
There are steps that you can take to slow down an
impending overheat condition. If your air conditioning is
on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to Floor and
the Fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
4. Speedometer
Indicates vehicle speed.226 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:Check the automatic transmission fluid level
before towing.Towing Tips — Electronic Speed Control (If
Equipped)
•
Don’t use in hilly terrain or with heavy loads.
•
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
•
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips — Cooling SystemTo reduce potential for engine and transmission over-
heating, take the following actions:•
City Driving
When stopped for short periods of time, put transmission
in NEUTRAL but do not increase engine idle speed.
•
Highway Driving
Reduce speed.
•
Air Conditioning
Turn off temporarily.
•

the normal range. If the pointer remains on the H (red)
mark for more than a minute, turn the engine off imme-
diately and call for service.

an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads “H”, pull
over and stop the vehicle with the engine at idle,
when safe. Turn the air conditioner off and wait until
the pointer drops back into the normal range. After
appropriate action has been taken, if the pointer
remains on the “H”, turn the engine off immediately,
and call for service.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
JACKING AND TIRE CHANGING
WARNING!
•
Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you
need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
•
The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
360 WHAT TO DO IN EMERGENCIES

8. Remove the wheel blocks and lower the jack until it is
free. Stow the lug wrench, and jack in their designated
location. Secure all parts using the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.
9. Place the deflated (flat) tire in the cargo area, have the
tire repaired or replaced as soon as possible.
10. Check the tire pressure as soon as possible. Correct
pressure as required.
JUMP-STARTING PROCEDURES DUE TO A LOW
BATTERY
WARNING!
Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is on. You can be hurt by the fan.

COOLING SYSTEM
WARNING!
•
When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
•
You 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 ChecksCheck engine coolant (antifreeze) protection every 12
months (before 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 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.
398 MAINTAINING YOUR VEHICLE

Cooling System — Drain, Flush and RefillThe system should be drained, flushed, and refilled at the
intervals shown in the “Maintenance Schedules” in Sec-
tion 8 of this manual.
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 CoolantUse only the manufacturers recommended coolant, refer
to Fluids, Lubricants and Genuine Parts for correct
coolant type.
CAUTION!
Mixing of coolants other than specified HOAT en-
gine coolants, may result in engine damage and may
decrease corrosion protection. If a non-HOAT coolant
is introduced into the cooling system in an emer-
gency, it should be replaced with the specified cool-
ant as soon as possible.
Do not use plain water alone or alcohol base 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 coolants. Use of Propylene
Glycol based coolants is not recommended.

Adding CoolantYour vehicle has been built with an improved engine
coolant that allows extended maintenance intervals. This
coolant can be used up to five Years or 100,000 miles
before replacement. To prevent reducing this extended
maintenance period, it is important that you use the same
coolant throughout the life of your vehicle. Please review
these recommendations for using Hybrid Organic Addi-
tive Technology (HOAT) coolant.
When adding coolant:•
The manufacturer recommends using Mopar
Antifreeze/Coolant five Year/100,000 Mile Formula
HOAT (Hybrid Organic Additive Technology).
•
Mix a minimum solution of 50% HOAT engine coolant
and distilled water. Use higher concentrations (not to
exceed 70%) if temperatures below34°F(37° C)
are anticipated.
•
Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
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.
Cooling System Pressure CapThe cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant recovery bottle.
