2004 DODGE INTREPID oil

Checking the oil while the vehicle is on level ground also
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 these engines.

176 MAINTAINING YOUR VEHICLE

The proper SAE viscosity grade of engine oil should be
selected based on the following recommendations and be
within the operating temperature shown in the engine oil
viscosity charts.
SAE 10W-30 oil is preferred for use in 3.5L engines within
the operating temperatures shown in the viscosity chart.
SAE 5W-30 engine oil is allowed for use in the 3.5L
engine during cold weather only to improve cold
weather starting.SAE 5W-30 oil is preferred for use in 2.7L engines within
the operating temperatures shown in the viscosity chart.
You are encouraged to use SAE 5W-30 oils to aid in low
temperature starting and for improved fuel economy.
Synthetic Engine Oils
There are a growing number of engine oils being pro-
moted as either synthetic or semi-synthetic. If you choose
to use such a product, useonlythose oils that meet the
American Petroleum Institute (API) and SAE viscosity
standard. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
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 of this manufacturer’s engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Mopar Engine Oil Filters are high
quality oil filters and are recommended.
Drive Belts – Check Condition and Tension
At the mileage 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 specificationsand procedures shown in the Service Manual. See the
Consumer Assistance section for information on ordering
a 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 mileage 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.
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.

Chassis Lubrication
Front Suspension Ball Joints
Inspect these ball joints whenever your vehicle is ser-
viced. They are permanently lubricated and do not
require periodic lubrication.
Steering Linkage
Inspect tie rod ends whenever the vehicle is serviced.
They are permanently lubricated and do not require
periodic lubrication.
Drive Shaft Universal Joints
Your vehicle has four constant velocity universal joints.
Periodic lubrication of these joints is not required. How-
ever, the joint boots should be inspected for external
leakage or damage when other maintenance is per-
formed.
If leakage or damage is evident, replace the universal
joint boot and grease immediately.
Continued operation could result in failure of the univer-
sal joint due to water and dirt contamination of the
grease. This would require complete replacement of the
joint assembly.
Body Mechanism Lubrication
Body and other operating mechanisms and linkages
should be inspected, cleaned, and lubricated, as required,
to maintain ease of operation and to provide protection
against rust and wear.
Before the application of any lubricant, the parts con-
cerned should be wiped clean to remove dust and grit;
after lubricating, excess oil or grease should be removed.

Hood Latch
When performing other under hood services, the hood
latch release mechanism and safety catch should be
inspected, cleaned, and lubricated.
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.
External Lock Cylinders
Lubricate the external lock cylinders twice a year, prefer-
ably in the fall and spring. Apply a small amount of
lubricant, such as Mopar Lock Cylinder Lubricant di-
rectly 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.
If you use a lubricant that cannot be dispensed directly
into the lock cylinder, apply a small amount of the
lubricant to the key. Insert the key into the lock cylinder,then proceed as described above, to distribute the lubri-
cant within the lock cylinder. Pay attention to trunk
hinges, especially during cold weather, to ensure ease of
trunk operation.
Other Body Mechanisms
The following body mechanisms should be inspected
and, if necessary, all pivot and sliding contact areas of
these components should be lubricated with the lubricant
specified as follows:

•
Door hinges
•Hood hinges
•Trunk hinges
Smooth White Body Lubricant - Such as Mopar
Spray White Lube:
•
Hood hinge springs and links
•Lock cylinders

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. This will remove accumula-
tions 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 fluid reservoir in the engine compartment should be
checked for fluid level at regular intervals. Fill the
reservoir with windshield antifreeze (not radiator anti-
freeze) rated not to freeze at -25°F (-31°C). Operate the
system for a few seconds to flush out the residual water.
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.
