2007 JEEP PATRIOT engine

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 (a
few 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 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.
²Do not overfill the coolant recovery bottle.
²Check coolant freeze point in the radiator and in the
coolant recovery bottle. If antifreeze needs to be
added, contents of coolant recovery bottle must also be
protected against freezing.
²If 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 pres-
sure tested for leaks.
²Maintain coolant concentration at 50% HOAT engine
coolant (minimum) and distilled water for proper
corrosion protection of your engine which contains
aluminum components.
²Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.

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 lamp 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. 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.
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. The
Manual 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 manufacturers recommended brake fluid, refer
to Fluids, Lubricants and Genuine Parts for correct fluid
type.

WARNING!
Use of a brake fluid that may have a lower initial
boiling point or 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.
Do not allow petroleum based fluid to contaminate 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-
turers 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 ªMaintenance Schedule located if section 8 of
this manual for the correct change interval for your type
of driving.
Special Additives
Do not add any materials (other than leak detection dyes)
to Continuously Variable Transaxle (CVT) Fluid
(CVTF+4). CVTF+4 is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Manual Transaxle
Lubricant Selection
Use only manufacturers recommended transmission
fluid. Refer to Fluids, Lubricants and Genuine Parts for
correct fluid type.

Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft rag. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp
rag.
2. Dry with a soft tissue.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the car to
wash them.Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Dry with a soft tissue.
FUSES/INTEGRATED POWER MODULE (IPM)
An Integrated Power Module is located in the engine
compartment near the air cleaner assembly. This center
contains cartridge fuses and mini fuses. A label that
identifies each component may be printed on the inside
of the cover. Refer to ªEngine Compartmentº in this
section of the owner's manual for the underhood location
of the Integrated Power Module (IPM).
