JEEP PATRIOT 2008 1.G Owners Manual

When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill.
Points To Remember
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 nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot coolant 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 recovery bottle.
•Check the coolant freeze point in the radiator and in
the coolant recovery bottle. If antifreeze needs to be
added, the contents of the coolant recovery bottle must
also be protected against freezing.
•If frequent coolant additions are required or if the level
in the coolant recovery bottle does not drop when the
engine cools, the cooling system should be pressure
tested for leaks.
•Maintain coolant concentration at 50% HOAT engine
coolant (minimum) and distilled water for proper
corrosion protection of your engine which contains
aluminum components.
•Make sure that the radiator and coolant recovery
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 also.

•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 coolant performance, poor gas
mileage, and increased emissions.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to the hoses nearest to high heat
sources such as the exhaust manifold. Inspect hose rout-
ing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Ensure nylon tubing in these areas has not melted or
collapsed.Inspect all hose connections such as clamps and cou-
plings, to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of degradation that could cause failure.Fuel System Connections
Electronic Fuel Injection high pressure fuel systems are
designed with tubes and special connects, connections
and clamps which have unique material characteristics to
provide adequate sealing and resist attack by deterio-
rated gasoline.
You are urged to use only the manufacturer’s-specified
tubes, connections and clamps, or their equivalent in
material and specification, in any fuel system servicing.
370 MAINTAINING YOUR VEHICLE

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to “Maintenance Schedule” under Section 8.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. 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 And Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect the surface of the hoses and nylon tubing for
evidence of heat and mechanical damage. Hard andbrittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling suggest deterioration of the rubber. Particu-
lar attention should be made to examining those hose
surfaces nearest to high heat sources, such as the exhaust
manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
Ensure nylon tubing in these areas has not melted or
collapsed.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before a hose is replaced
based on leakage.
MAINTAINING YOUR VEHICLE 371

NOTE:Inspection of brake hoses should be done when-
ever the brake system is serviced and at every engine oil
change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
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 brakefluid 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 amanual
transaxle, 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. Themanual
transaxleclutch release system should not require fluid
replacement during the life of the vehicle. If the brake
fluid reservoir is low and the brake system does not
indicate any leaks or other problems, it may be a result of
a leak in the hydraulic clutch release system. See your
local authorized dealer for service.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts” under
Section 8.
372 MAINTAINING YOUR VEHICLE

WARNING!
Use of a brake fluid that may have a lower initial
boiling point or is unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident.
CAUTION!
Use of improper brake fluids will affect overall
clutch system performance. Improper brake fluids
may damage the clutch system resulting in loss of
clutch function and the ability to shift the transaxle.
WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter.
NOTE:Do not allow petroleum-based fluid to contami-
nate the brake fluid as seal damage will result!
Automatic Transaxle (CVT)
Selection Of Lubricant
It is important that the proper lubricant is used in the
transaxle to assure optimum transaxle performance. Use
only the manufacturer’s recommended transmission
fluid which has been formulated with special metal to
metal friction coefficient additives to provide the proper

steel belt traction on the drive and driven pulleys. Refer
to “Fluids, Lubricants and Genuine Parts” for correct
fluid type.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid will cause belt slip and
result in a complete transmission failure! Refer to
“Fluids, Lubricants, and Genuine Parts” for correct
fluid type.
Fluid Level Check
The fluid level in the automatic transaxle should be
checked only by a trained technician.
Fluid And Filter Changes
Refer to the “Maintenance Schedule” in Section 8 of this
manual for the correct change interval.
Special Additives

Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extremehot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes of corrosion are:
•Road salt, dirt and moisture accumulation.
•Stone and gravel impact.
•Insects, tree sap and tar.
•Salt in the air near sea coast localities.
•Atmospheric fallout/industrial pollutants.
376 MAINTAINING YOUR VEHICLE

Washing
•
Wash your vehicle regularly. Always wash your ve-
hicle in the shade using MoparCar Wash or a mild
car wash soap, and rinse the panels completely with
clear water.
•If insects, tar or other similar deposits have accumu-
lated on your vehicle, use MoparSuper Kleen Bug
and Tar Remover to remove.
•Use MoparCleaner Wax to remove road film, stains
and to protect your paint finish. Take care never to
scratch the paint.
•Avoid using abrasive compounds and power buffing
that may diminish the gloss or thin out the paint
finish.
CAUTION!
Do not use abrasive or strong cleaning materials such
as steel wool or scouring powder, which will scratch
metal and painted surfaces.
Special Care
•
If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least once
a month.
•It is important that the drain holes in the lower edges
of the doors, rocker panels and trunk be kept clear and
open.
•If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
MAINTAINING YOUR VEHICLE 377

•If your vehicle is damaged due to an accident or
similar cause which destroys the paint and protective
coating, have your vehicle repaired as soon as pos-
sible. The cost of such repairs is considered the respon-
sibility of the owner.
•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure that such materials are well
packaged and sealed.
•If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
•Use Mopartouch up paint on scratches as soon as
possible. Your authorized dealer has touch up paint to
match the color of your vehicle.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly with
a mild soap and water to prevent corrosion. To removeheavy soil, use MoparWheel Cleaner or select a non-
abrasive, non-acidic cleaner. Do not use scouring pads,
steel wool, a bristle brush or metal polishes. Only Mo-
parcleaners are recommended. Do not use oven cleaner.
Avoid automatic car washes that use acidic solutions or
harsh brushes that may damage the wheels’ protective
finish.
YES EssentialsFabric Cleaning Procedure – If
