engine DODGE CHARGER SRT 2007 6.G Repair Manual

WARNING!
You can be badly injured working on or around a
motor vehicle. Only do 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 me-
chanic.
MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
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.
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 in the ªSAFEº range. Adding 1.0 quart (1.0L)
of oil when the reading is at the bottom of the ªSAFEº
range will result in an oil level at the top of the ªSAFEº
range on these engines.

NOTE:Under no circumstances should oil change
intervals exceed 6,000 miles (10 000 km) or 6 months,
whichever comes first.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends full synthetic engine oils that meet the
American Petroleum Institute (API) categories of SM or
SM/CF, and meet the requirements of DaimlerChrysler
Material Standard MS-10725.
The manufacturer recommends the use of a full synthetic
engine oil, such as Mobil 1tSAE 0W-40 or equivalent.
Engine Oil Viscosity (SAE Grade)
The proper SAE viscosity grade of engine oil should be
selected based on the following recommendation and be
within the operating temperature shown in the engine oil
viscosity chart.The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the ªEngine Com-
partmentº illustration in this section.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.

Disposing of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
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 and oil filters 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
This manufacturer's engines have a full-flow type 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. MopartEngine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts Ð Check Condition and Tension
Belt tension is controlled by means of an automatic
tensioner. Therefore, no belt tension adjustments are
required. However, belt and belt tensioner conditionshould be inspected at the specified intervals and re-
placed if required. Improper belt tension can cause belt
slippage and failure. Low generator belt tension can
cause battery failure.
At the mileage indicated in the maintenance schedule,
inspect belt and belt tensioner condition. Inspect belts for
evidence of cuts, cracks, glazing, or frayed cords and
replaced if there is indication of damage, which could
result in belt failure. Also, check belt routing to make sure
there is no interference between the belts and other
engine components. See your authorized dealer for ser-
vice.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Malfunctioning spark plugs can damage the cata-
lytic converter. For proper type of replacement spark
plugs, refer to the ªVehicle Emission Control Informa-
tionº label in the engine compartment.

Engine Air Cleaner Filter
For normal driving conditions, inspect and replace the
engine air cleaner filter at the intervals shown on Sched-
ule ªA.º For vehicles driven frequently in dusty or under
severe conditions, inspect and replace the engine air
cleaner filter at the intervals shown on Schedule ªB.º
WARNING!
The air induction system (air cleaner, hoses, etc) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc) 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 induction system (air cleaner,
hoses, etc) removed. Failure to do so can result in
serious personal injury.
Fuel Filter
A plugged fuel filter can cause stalling, limit the speed at
which a vehicle can be driven or cause hard starting.
Should an excessive amount of dirt accumulate in the
fuel tank, 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 tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
MAINTAINING YOUR VEHICLE 271

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.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
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.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this should occur,
safely bring the vehicle to a complete stop, shut the
engine off, and allow the vehicle to cool. Thereafter,
obtain service, including a tune-up to manufacturer's
specifications immediately.
To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
272 MAINTAINING YOUR VEHICLE

²Do not try to start engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Maintenance-Free Battery
The top of the MAINTENANCE-FREE battery is perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:The battery is stored under an access cover in
the trunk. Remote battery terminals are located in the
engine compartment for jump starting.Battery Location

Refer to the ªMaintenance Scheduleº in this manual for
the recommended air conditioning filter replacement
intervals.
Power Steering Ð Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturer's recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from allsurfaces. Refer to ªFluids, Lubricants, and Genuine
Partsº in this section for the correct fluid type.
Front & Rear Suspension Ball Joints
The suspension ball joints should be inspected for exter-
nal leakage or damage when other maintenance is per-
formed.
Steering Linkage
The tie rod end ball joints should be inspected for
external leakage or damage when other maintenance is
performed.
Body Lubrication
Locks and all body pivot points, including seat tracks,
door hinges, trunk hinges, and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation of any lubricant, the parts concerned should be
wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism,
and safety catch should be cleaned and lubricated.
276 MAINTAINING YOUR VEHICLE

The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as MopartLock
Cylinder Lubricant or equivalent directly into the lock
cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove accu-
mulations of salt or road film.
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. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
Windshield Washers
The windshield washer fluid reservoir is located in the
front of the engine compartment on the passenger side of
the vehicle. Be sure to check the fluid level at regular
intervals. Fill the reservoir with windshield washer sol-
vent (not radiator antifreeze) and operate the system for
a few seconds to flush out the residual water.
The fluid reservoir will hold nearly 1 gallon (4 liters) of
washer fluid when the message ªLow Washer Fluidº
appears in the Electronic Vehicle Information Center
(EVIC).
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.

Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
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, refer
to ªExhaust Gasº in the ªSafety Tipsº section of this
manual.
Cooling System
WARNING!
²When 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.
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
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 any
