2005 CHRYSLER CROSSFIRE SRT engine

WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the proper equipment.
If you have any doubt about your ability to perform
a service job, take your vehicle to a competent
technician.
MAINTENANCE PROCEDURES
The pages that follow contain the maintenance service
recommended by the engineers who designed your ve-
hicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop.
You can check the oil level using the procedure described
in Checking Engine Oil Level in the Understanding Your
Instrument Panel section, or by checking the engine oil
dipstick.
MAINTAINING YOUR VEHICLE 195

The best time to check the engine oil level is about 5
minutes after a fully warmed engine is shut off, or before
starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level between the MIN and MAX markings on the
dipstick. Adding one quart of oil when the reading is at
the MIN mark will result in a MAX reading on this
engine.

Change Engine Oil
The oil change interval for your Crossfire is initially set at
7,000 miles (Canada: 11,000 km).
The Flexible Service System (FSS) in your vehicle evalu-
ates engine temperature, oil level, vehicle speed, engine
speed, distance driven, and the time elapsed since your
last service. It determines when your vehicle needs
maintenance service and alerts you in advance. The next
necessary service is indicated by the FSS in your instru-
ment cluster.
NOTE:Also see the FSS system details in the Under-
standing Your Instrument Panel section of this manual.
Very light duty driving cycles (most trips more than 10
miles [16 km] at moderate speeds in moderate tempera-
ture conditions) can extend the service interval beyond
7,000 miles (Canada: 11,000 km).
IfANYof the following apply to your driving, the oil
change interval can be reduced significantly:
•Day and night temperatures are below 32°F(0°C)
•Stop-and-go driving
•Extensive engine idling
•Driving in dusty conditions
•Short trips of less than 10 miles (16 km)
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C)
•Taxi, Police, or delivery service (commercial service)
Observe the oil change interval indicated by your FSS
system. This system will monitor the driving conditions
seen by your vehicle, and will recommend the best
interval for servicing your vehicle to maintain it in top
condition.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.

Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, only use synthetic engine
oils, approved to MB 229.3 or MB 229.5, such as Mobil 1
SAE 0W-40. The FSS may not alert for an oil change at the
proper interval if an unapproved engine oil is used;
engine damage and reduced engine life may result.
Materials Added To Engine Oils
Do not add materials (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, indiscriminately discarded, can
present a problem to the environment. Contact your
dealer, service station, or governmental agency for advice
on how and where used oil can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All DaimlerChrysler Corporation engines have a full-
flow type disposable oil filter. Use a filter of this type for
replacement. The quality of replacement filters varies
considerably. Only high quality filters should be used to
assure most efficient service. MoparEngine Oil Filters
are high quality oil filters and are recommended.

Drive Belts - Check Condition and Tension
At the distance shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specifications
and procedures shown in the Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the distance specified in the appropriate main-
tenance chart. The entire set should be replaced if there is
any malfunction due to a faulty spark plug. Check the
specifications section for the proper type of spark plug
for use in your vehicle.
Engine Air Cleaner Filter
Under normal driving conditions, replace the air filter at
each interval called out by FSS.
WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner unless such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle with
the air cleaner removed. Failure to do so can result in
serious personal injury.
Engine Fuel Filter
A plugged fuel filter can cause hard starting or limit the
speed at which a vehicle can be driven. Should an
excessive amount of dirt accumulate in the fuel tank,
frequent filter replacement may be necessary. See your
authorized dealer for service.

Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly serviced to assure
proper catalyst operation and prevent possible catalyst
damage.
If the CHECK ENGINE light is flashing, immediate
service is required.CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
200 MAINTAINING YOUR VEHICLE

In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to DaimlerChrysler Corpo-
ration’s specifications, should be obtained immediately.
To minimize the possibility of catalyst damage:
•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected for a prolonged period.
Ignition Wiring System
The ignition cables should be kept clean and properly
connected. Terminals should be fully seated. Cracked,
damaged, or faulty cables should be replaced.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits.
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.
Maintenance-Free Battery
The top of the maintenance-free battery is permanently
sealed. You will never have to add water, nor is periodic
maintenance required.

It is important to maintain proper lubrication to insure
that the hood mechanisms work properly and safely.
Multi-Purpose Lubricant, NLGI Grade 2, should be ap-
plied sparingly to all pivot and sliding contact areas.
Driver’s Door Lock Cylinder
The driver’s door lock cylinder should be lubricated
twice a year, preferably in the fall and spring. Apply a
small amount of a high quality lubricant, such as Mopar
Lock Cylinder Lubricant directly into the lock cylinder
(avoid excess lubricant).
Insert the key into the lock cylinder and rotate from the
unlocked to the locked position without adding more
lubricant. Repeat this procedure three or four times. Wipe
all the lubricant off the key with a clean cloth, to avoid
soiling clothing.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild non-abrasive cleaner, or use the washer solvent.
This will remove accumulations of salt or road film and
help reduce streaking and smearing.Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield. Avoid using the wiper blades to
remove frost or ice from the windshield. Make sure that
they are not frozen to the glass before turning them on to
avoid damaging the blade. Keep the blade rubber out of
contact with petroleum products such as engine oil,
gasoline, etc.
Windshield Wiper Blade Replacement
1. Lift the wiper arm away from the glass.
2. Rotate the blade 45 degrees to gain access to the
release tab.
3. Push the release tab as shown in the illustration and
slide the wiper blade assembly down along the arm.
Gently place the wiper arm on the windshield.
