2021 DODGE CHALLENGER low oil pressure

SERVICING AND MAINTENANCE253
(Continued)
CHECKING OIL LEVEL
To ensure 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 ten minutes after a fully warmed up engine
is shut off.
Checking the oil while the vehicle is on level ground
will improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low
end of the range and MAX at the high end of the
range.
Crosshatched zone marked with dimples at the
MIN and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 quart (1 liter) of oil when the reading is at
the low end of the dipstick range will raise the oil
level to the high end of the range marking.
ADDING WASHER FLUID
The windshield washer fluid reservoir is located in
the front of the engine compartment. Be sure to
check the fluid level at regular intervals. Fill the
reservoir with windshield washer solvent (not
radiator antifreeze) and operate the system for a
few seconds to flush out the residual water.
When refilling the washer fluid reservoir, apply
some washer fluid to a cloth or towel and wipe the
wiper blades clean. This will help blade
performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or mixture
that meets or exceeds the temperature range of
your climate. This rating information can be found
on most washer fluid containers.
The fluid reservoir will hold nearly 1 Gallon (4
Liters) of washer fluid when the message “Low
Washer Fluid” appears in the instrument cluster.
WARNING!
Never smoke while working in the engine
compartment: gas and inflammable vapors
may be present, with the risk of fire.
Be very careful when working in the engine
compartment when the engine is hot: you may
get burned. Do not get too close to the radiator
cooling fan: the electric fan may start; danger
of injury. Scarves, ties and other loose clothing
might be pulled by moving parts.
CAUTION!

Be careful not to confuse the various types of
fluids while topping up: they are not compatible
with each other! Topping up with an unsuitable
fluid could severely damage your car.

The oil level must never exceed the MAX mark.
Always top up using engine oil of the same
specifications as what is already in the engine.
If the engine oil is being topped up, wait for the
engine to cool down before loosening the filler
cap, particularly for vehicles with aluminium
cap (if equipped). WARNING: risk of burns!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
CAUTION!CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This could
damage your engine.

T/A Air Filter Maintenance — If Equipped
Clean Engine Air Filter
The scheduled air filter cleaning interval is
30,000 miles (48,280 km), or if in a dusty
environment the engine air filter should be
checked periodically to ensure optimal air flow.
Cleaning your engine air filter with the
recommended Mopar® Performance Air Filter
Service Kit is not required if you can still see any
part the wire screen on the entire air filter
regardless of how dirty it may appear. When any
part of the wire screen is no longer visible on the air
filter, that is an indication it is time to clean the air
filter.

1. Spray the air filter with the recommended
Mopar® air filter cleaner and let sit for at
least 10 minutes to loosen dirt, before
rinsing.

NOTE:Never use strong detergents, high pressure, or
gasoline on air filter.
2. Rinse the air filter with cool low-pressure water applied from the inside (clean side) out in
order to flush the dirt out of the filter. Continue
to rinse the filter until all traces of the cleaner
have been removed.
NOTE:It may be necessary to repeat steps 1 and 2 if the
air filter is not completely clean.
3. After rinsing the air filter, gently shake off the excess water and allow air filter to dry
naturally. Do not apply oil until air filter is
completely dry.
NOTE:Do not use forced air pressure as it may damage
the filtering capabilities of the filter’s microfibers
and also void its warranty.
4. Using the Mopar® Performance Air Filter Service Kit, spray oil evenly along the crown of
each filter pleat holding the nozzle about
3 inches (76 mm) away from the air filter. One
spray per 2 square inches (1,290 square mm)
of air filter. With one complete coat of oil, let it
wick (saturate) for about 20 minutes, and if
required touch up any light areas on either
side of the filter.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty
Information Book, for further warranty infor -
mation.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an
experienced technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.8
