2006 CHRYSLER CROSSFIRE engine

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.
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. Do not store ethylene glycol based engine
coolant in open containers or allow it to remain in
puddles on the ground. Prevent ingestion by animals or
children. If ingested by a child, contact a physician
immediately.
Selection Of Coolant
Use only coolant approved to MB 325.0, such as Valvoline
GO5, or an equivalent extended life coolant. Refer to the
recommended Fluids, Lubricants and Genuine Parts for
correct coolant type.
CAUTION!
Failure to use the proper antifreeze could cause
radiator plugging and engine overheating. Do not
mix antifreeze brands or types. Do not use plain
water alone or alcohol base antifreeze products. Do
not use additional rust inhibitors or antirust prod-
ucts, as they may not be compatible with the radiator
coolant and may plug the radiator.
Adding Coolant
When adding coolant, a minimum solution of 50% eth-
ylene glycol antifreeze coolant and water should be used.
Use higher concentrations (not to exceed 70%) if tempera-
tures below -34°F (-37°C) 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.
NOTE:Mixing coolant types other than Moparprod-
ucts will decrease the life of the engine coolant and will
require more frequent coolant changes.

Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing,
according to the temperatures occurring in the area
where the vehicle is operated.
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 reserve tank.
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 WHEN HOT”
near the cooling system reservoir cap are a safety
precaution. Never add 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.
WARNING!
Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or engine
damage may result.
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 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 bottle.
•Check coolant freeze point in the system.
224 MAINTAINING YOUR VEHICLE

•If frequent coolant additions are required, or if the
level in the recovery bottle does not drop when the
engine cools, the cooling system should be pressure
tested for leaks.
•Maintain a coolant concentration of a minimum of 50%
ethylene glycol Extended Life Coolant and high qual-
ity water with recommended antifreeze for proper
corrosion protection of your engine cooling system
that contains aluminum components.
•Make sure that the radiator and coolant 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.
•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 coolant performance, poor fuel
economy, and increased emissions.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.
Pay particular attention to the hoses nearest to high heat
sources such as the exhaust manifold. Inspect hose rout-
ing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps
and couplings to make sure they are secure and no leaks
are present. Components should be replaced immedi-
ately if there is any evidence of degradation that could
cause failure.
Brakes
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the Mainte-
nance section.

WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, checking, tears, cuts, abrasions, and excessive
swelling suggest deterioration of the rubber. Particular
attention should be made to examining those hose sur-
faces nearest to high heat sources, such as the exhaust
manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
Insure nylon tubing in these areas has not melted or
collapsed.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before a hose is replaced
based on leakage.
NOTE:Inspection of brake hoses should be done
whenever the brake system is serviced and at every
engine oil change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.

NOTE:Refer to Section 8 of this manual for Mainte-
nance Schedules.
Manual Transmission
Selection of Lubricant
No fluid service is required. Use only fluid approved to
MB 236.2. SAE 5W-20 engine oil, meeting API SL or GF-3,
may be substituted. Refer to the Recommended Fluids,
Lubricants and Genuine Parts section for the correct fluid
type.
Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more than 3/16 inch (4.76 mm) below the
bottom of the hole.
CAUTION!
Do not overfill. Dirt and water in the transmission
can cause serious damage. To prevent dirt and water
from entering the transmission after checking or
replenishing fluid, make certain that the dipstick cap
is seated properly.
Add fluid, if necessary, to maintain the proper level.
Frequency of Fluid Change
Under normal operation conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary unless the
lubricant has become contaminated with water. If con-
taminated with water, the fluid should be changed im-
mediately.
Special Additives
Do not add any fluid additives to the transmission. The
only exception to this policy is the use of special dyes to
aid in detecting fluid leaks. The use of transmission
sealers should be avoided as this may adversely affect
seals.
