coolant temperature CHRYSLER PT CRUISER 2005 1.G Owners Manual

6. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the engine is critically hot, a warning chime
will sound 10 times. After the chime turns off, the
engine will still be critically hot until the light goes out.
7. Turn Signal Indicators
The arrows will flash in unison with the exterior
turn signal, when using the turn signal lever.
NOTE:Turn signal bulbs are located in the Instrument
Panel. (See page 97 for more information.)
8. 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 theH(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 theH(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.
128 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!
Driving with a hot 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. 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.
234 WHAT TO DO IN EMERGENCIES

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 Checks
Check 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 radiator for an accumulation of
bugs, leaves, etc. Clean the radiator by gently spraying
water from a garden hose at the back of the core.
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.
272 MAINTAINING YOUR VEHICLE

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
coolant from the radiator drain cock. If the cap is sealing
properly, the engine coolant (antifreeze) will begin to
drain from the coolant recovery bottle. DO NOT RE-
MOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Cooling System—Drain, Flush and Refill
At the intervals shown on the Maintenance Schedules,
the system should be drained, flushed and refilled.
If the solution is dirty and 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. Discard oil antifreeze
solution.
Selection Of Coolant
Use only the manufacturers recommended coolant, refer
to Recommended Fluids, Lubricants and Genuine Parts
for correct coolant type.
MAINTAINING YOUR VEHICLE 273

CAUTION!
Mixing of coolants other than specified engine cool-
ants, may result in engine damage that may not be
covered under the new vehicle warranty, and de-
creased corrosion protection. If a non-HOAT coolant
is introduced into the cooling system in an emer-
gency, it should be replaced with the specified
coolant 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 Coolant
When adding coolant, or refilling the system, a minimum
solution of 50% recommended HOAT ethylene glycol
engine coolant (antifreeze) and distilled water should be
used. Use higher concentrations (not to exceed 70%) if
temperatures below
37°C(
34°F ) are anticipated.
Use only high purity water such as distilled or deionized
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.
274 MAINTAINING YOUR VEHICLE

Cooling System Pressure Cap
The 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.
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 coolant when the engine is overheated.
Do not loosen or remove the cap to cool an over-
heated 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.
Engine Coolant Disposal
Used ethylene glycol based engine 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 ethylene glycol based engine 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 any ground spills immediately.
Coolant Level
The coolant recovery bottle provides a quick visual
method for determining that the coolant level is ad-
equate. With the engine idling, and warm to normal
operating temperature, the level of the coolant in the
bottle should be between the“FULL”and“ADD”marks.
The radiator normally remains completely full, so there is
no need to remove the radiator cap unless checking for
coolant freeze point or replacing coolant. Advise your
MAINTAINING YOUR VEHICLE 275

service attendant of this. As long as the engine operating
temperature is satisfactory, the coolant recovery 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 kilome-
ters (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 accumulation on the radiator and being vapor-
ized when the thermostat opens, allowing hot water 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 recovery bottle.
•Check coolant freeze point in the system.
•If frequent coolant additions are required, the cooling
system should be pressure tested for leaks.
•Maintain coolant concentration at 50% HOAT ethylene
glycol engine coolant (minimum) and distilled water
for proper corrosion protection of your engine which
contains aluminum components.
•Make sure that the radiator and coolant recovery
bottle hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle has
air conditioning, keep the front of the condenser clean,
also.
