radiator cap JEEP COMPASS 2017 2.G Owners Manual

•In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the pointer rises to the H (red) mark, the
instrument cluster will sound a chime. When safe, pull
over and stop the vehicle with the engine at idle. Turn
off the air conditioning and wait until the pointer
drops back into the normal range. If the pointer
remains on the H (red) mark for more than a minute,
turn the engine off immediately and call for service.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector cannot be
moved out of the PARK position, you can use the following
procedure to temporarily move the gear selector:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Using a small screwdriver or similar tool, remove the
gear selector override access cover (located on the right
side of the gear selector housing).

IN CASE OF EMERGENCY 271

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 five minutes after a fully
warmed engine is shut off. Do not check oil level before
starting the engine after it has sat overnight. Checking
engine oil level when the engine is cold will give you an
incorrect reading.
Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings. Maintain the oil level between the
range markings on the dipstick. The range markings will
consist of a crosshatch zone which depicts the MIN at the
low end of the range and MAX at the high end of the range.
Adding 1 quart (1 liter) of oil when the reading is at the low
end of the indicated range will result in the oil level at the
full end of the indicator range.
CAUTION!
Do not overfill the engine. Overfilling the engine will
cause oil aeration, which can lead to loss of oil pressure
and an increase in oil temperature. This could damage
your engine. Also, be sure the oil fill cap is replaced
and tightened after adding oil.
Cooling System
WARNING!
•When working near the radiator cooling fan, discon-
nect 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.
• You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not 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.
286 SERVICING AND MAINTENANCE

CAUTION!(Continued)
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
vehicle.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE: Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately. To minimize the possibility of catalytic converter damage:
•
Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
Cooling System
WARNING!
•Turn vehicle off and disconnect the fan motor lead
before working near the radiator cooling fan.
• You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never open a cooling system pressure cap
when the radiator or coolant bottle is hot.

294 SERVICING AND MAINTENANCE

WARNING!(Continued)
•Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised. The
fan starts automatically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling fan, discon-
nect 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.
• You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not 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 appli-
cable). If the engine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained, flushed, and
refilled with fresh engine coolant (antifreeze). Check the
front of the A/C condenser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a
garden hose vertically down the face of the condenser.
Check the coolant recovery bottle tubing for brittle rubber,
cracking, tears, cuts, and tightness of the connection at the
bottle and radiator. Inspect the entire system for leaks.
Cooling System — Drain, Flush And Refill
NOTE:
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 your local autho-
rized dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
OAT coolant (antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.

SERVICING AND MAINTENANCE 295

•Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant (anti-
freeze) 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 prop-
erly. 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 your local
authorized dealer.
• Mixing engine coolant (antifreeze) 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 pos-
sible.Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery tank.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over-
heated. 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 speci-
fied for your vehicle. Personal injury or engine
damage may result.

MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• 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 coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” for the proper maintenance
intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly 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.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
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. Fluid level can be expected to fall as the brake
pads wear. The brake fluid level should be checked when
the pads are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.
NOTE:If your vehicle is equipped with a manual trans-
mission, the brake fluid reservoir supplies fluid to both the
brake system and the clutch release system. The two
systems are separated in the reservoir, and a leak in one
system will not affect the other system. The manual
transmission clutch release system should not require fluid
replacement during the life of the vehicle. If the brake fluid
