2023 CHRYSLER VOYAGER check engine light

206SERVICING AND MAINTENANCE
(Continued)

As long as the engine operating temperature is satisfactory, the
coolant bottle need only be checked once a month.

When additional coolant is needed to maintain the proper
level, it should be added to the coolant bottle. Do not
overfill.
See an authorized dealer for service.
Cooling System Notes
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 normally a result of
moisture from rain, snow, or high humidity accumulating
on the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) 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 expansion bottle.
 Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant needs
to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
 If frequent engine coolant additions are required, the
cooling system should be pressure tested for leaks. 
Maintain engine coolant concentration at a minimum
of 50% OAT coolant (conforming to MS.90032) and
distilled water for proper corrosion protection of your
engine which contains aluminum components.
 Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
 Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
 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 engine cooling performance,
poor gas mileage, and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically.
For the proper maintenance intervals
Úpage 193.
Brake Master Cylinder
The fluid in the master cylinder should be checked when
performing under hood services or immediately if the
Brake Warning Light is illuminated.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
level up to the requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be expected to
fall as the brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
Use only manufacturer recommended brake fluid
Úpage 239.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. 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 would not have your full braking capacity
in an emergency.
WARNING!
Use only manufacturer recommended brake fluid Úpage 239. Using the wrong type of brake fluid can
severely damage your brake system and/or impair its
performance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.

 To avoid contamination from foreign matter or moisture,
use only new brake fluid or fluid that has been in a tightly
closed container. Keep the master cylinder reservoir cap
secured at all times. Brake fluid in an open container
absorbs moisture from the air resulting in a lower boiling
point. This may cause it to boil unexpectedly during hard
or prolonged braking, resulting in sudden brake failure.
This could result in a collision.

236TECHNICAL SPECIFICATIONS
Tighten the lug nuts/bolts in a star pattern until each nut/
bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it halfway).

Torque Patterns

After 25 miles (40 km) check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly tightened.
FUEL REQUIREMENTS

While operating on gasoline with the required octane number,
hearing a light knocking sound from the engine is not a cause
for concern. However, if the engine is heard making a heavy
knocking sound, see a dealer immediately. Use of gasoline with
a lower than recommended octane number can cause engine
failure and may void or not be covered by the New Vehicle
Limited Warranty.

Poor quality gasoline can cause problems such as
hard starting, stalling, and hesitations. If you experience
these symptoms, try another brand of gasoline before
considering service for the vehicle.
3.6L ENGINE
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.
This engine is designed to meet all emissions
regulations and provide optimum fuel economy
and performance when using high quality
unleaded regular gasoline having a posted
octane number of 87 as specified by the (R+M)/2 method.
The use of higher octane premium gasoline is not
required, as it will not provide any benefit over regular
gasoline in these engines.
REFORMULATED GASOLINE
Many areas of the country require the use of cleaner
burning gasoline referred to as “reformulated gasoline”.
Reformulated gasoline contains oxygenates and are
specifically blended to reduce vehicle emissions and
improve air quality. The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and fuel
system components.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited
Warranty.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15).
Use of these blends may result in starting and
drivability problems, damage critical fuel system
components, cause emissions to exceed the applicable
standard, and/or cause the Malfunction Indicator Light
to illuminate. Please observe pump labels as they
should clearly communicate if a fuel contains greater
than 15% ethanol (E-15).
