2023 JEEP COMPASS coolant level

SERVICING AND MAINTENANCE281
Use only high purity water such as distilled or
deionized water when mixing the water/engine
coolant solution. The use of lower quality water
will reduce the amount of corrosion protection
in the engine cooling system.
NOTE:
It is the owner's responsibility to maintain the
proper level of protection against freezing
according to the temperatures occurring in the
area where the vehicle is operated.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system, please contact an authorized
dealer.
Mixing engine coolant types is not recom -
mended and can result in cooling system
damage. If HOAT and OAT coolant are mixed in
an emergency, have a authorized dealer drain,
flush, and refill with OAT coolant (conforming to
MS.90032) as soon as possible.
Cooling System Pressure Cap

The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that engine
coolant will return to the radiator from the coolant
expansion bottle/recovery tank (if equipped).
The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is
a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent
ingestion by animals or children, do not store
ethylene glycol-based coolant in open containers
or allow it to remain in puddles on the ground.
If ingested by a child or pet, seek emergency
assistance immediately. Clean up any ground spills
immediately.
Coolant Level
The coolant expansion bottle provides a quick
visual method for determining that the coolant
level is adequate. With the engine off and cold, the
level of the engine coolant (antifreeze) in the bottle
should be between the “MIN” and “MAX” marks.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional engine coolant is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
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.
WARNING!
Do not open hot engine cooling system. Never
add engine coolant (antifreeze) when the
engine is overheated. Do not loosen or
remove the cap to cool an overheated engine.
Heat causes pressure to build-up in the
cooling system. To prevent scalding or injury,
do not remove the pressure cap while the
system is hot or under pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.

282SERVICING AND MAINTENANCE
(Continued)
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 corro-
sion 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 neces -
sary, 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
Ú page 268.
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 the manufacturer recommended brake
fluid Ú
page 324.
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 the manufacturer recommended
brake fluid Úpage 324. 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 a 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.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
