SERVICING AND MAINTENANCE

Cooling System — Drain, Flush And Refill

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.
If the engine coolant is dirty or contains visible

sediment, have an authorized dealer clean and

flush with OAT coolant (conforming to MS.90032).

page 240.

NOTE:



Mixing of engine coolant other than specified

OAT engine coolant, may result in engine

damage and may decrease corrosion protec

-

tion. OAT engine coolant is different and should

not be mixed with Hybrid Organic Additive Tech

-

nology (HOAT) engine coolant or any “globally

compatible” coolant. If a non-OAT engine

coolant is introduced into the cooling system in

an emergency, the cooling system will need to

be drained, flushed, and refilled with fresh OAT

coolant (conforming to MS.90032), by an autho

-

rized dealer as soon as possible.



Do not use water alone or alcohol-based engine

coolant products. Do not use additional rust

inhibitors or antirust products, as they may not

be compatible with the radiator engine coolant

and may plug the radiator.



This vehicle has not been designed for use with

propylene glycol-based engine coolant. Use of

propylene glycol-based engine coolant is not

recommended.



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.

Adding Coolant

Your vehicle is built with engine coolant (OAT

coolant conforming to MS.90032) that allows

extended maintenance intervals. This engine

coolant can be used up to 10 years or

150,000 miles (240,000 km) before replacement.

To prevent reducing this extended maintenance

period, it is important that you use the same

engine coolant (OAT coolant conforming to

MS.90032) throughout the life of your vehicle.

Please review these recommendations for using

OAT engine coolant that meets the requirements of

the manufacturer Material Standard MS.90032.

When adding engine coolant:



We recommend using Mopar® Antifreeze/

Coolant 10 Year/150,000 Mile (240,000 km)

Formula OAT that meets the requirements of the

manufacturer Material Standard MS.90032.



Mix a minimum solution of 50% OAT engine

coolant that meets the requirements of the

manufacturer Material Standard MS.90032

and distilled water. Use higher concentrations

(not to exceed 70%) if temperatures below

−34°F (−37°C) are anticipated. Please contact

an authorized dealer for assistance.



Use only high purity water such as distilled or

deionized water when mixing the water/engine

coolant (antifreeze) solution. The use of lower

quality water will reduce the amount of corro

-

sion 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.

SERVICING AND MAINTENANCE



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 a local 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 an 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, and to ensure that engine coolant

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.

The image on the coolant system

pressure cap is a reminder that the

radiator contains hot engine coolant

under pressure.

Disposal Of Used Coolant

Used ethylene glycol-based coolant is a regulated

substance requiring proper disposal. Check with

your local authorities to determine the disposal

rules for your community. To prevent ingestion, do

not store ethylene glycol-based coolant in open

containers or allow it to remain in puddles on the

ground, clean up immediately. If ingested, seek

emergency assistance 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 in the bottle should

be between the “MIN” and “MAX” marks.
The radiator normally remains completely full, so

there is no need to remove the radiator/coolant

pressure cap unless checking for engine coolant

freeze point or replacing coolant. Advise an

authorized dealer of this. As long as the engine

operating temperature is satisfactory, the coolant

only needs to be checked once a month.
When additional engine coolant is needed to

maintain the proper level, only OAT coolant that

meets the requirements of the manufacturer

Material Standard MS.90032 should be added to

the coolant bottle. Do not overfill.

WARNING!



Do not open a 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.

Cooling System Notes

NOTE:

When the vehicle is stopped after a few miles/kilo

-

meters 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 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 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.

In order to ensure brake system performance, all

brake system components should be inspected

periodically. For the proper maintenance intervals

Ú

page 190.

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 241.

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

Ú

page 241. 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.

RANSMISSION

Selection Of Lubricant

It is important to use the proper transmission fluid

to ensure optimum transmission performance and

life. Use only the manufacturer specified

transmission fluid

Ú

page 241. It is important to

maintain the transmission fluid at the correct level

using the recommended fluid.

NOTE:

No chemical flushes should be used in any trans

-

mission; only the approved lubricant should be

used.

Special Additives

It is strongly recommended against using any

special additives in the transmission. Automatic

Transmission Fluid (ATF) is an engineered product

and its performance may be impaired by

supplemental additives. Therefore, do not add any

fluid additives to the transmission. Avoid using

transmission sealers as they may adversely affect

seals.



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.



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.



Do not allow petroleum based fluid to contam

-

inate the brake fluid. Brake seal components

could be damaged, causing partial or

complete brake failure. This could result in a

collision.

WARNING!

CAUTION!

Using a transmission fluid other than the

manufacturer recommended fluid may cause

deterioration in transmission shift quality and/or

torque converter shudder

Ú

page 241.

CAUTION!

Do not use chemical flushes in your

transmission as the chemicals can damage your

transmission components. Such damage is not

covered by the New Vehicle Limited Warranty.

SERVICING AND MAINTENANCE

Fluid Level Check

The fluid level is preset at the factory and does not

require adjustment under normal operating

conditions. Routine fluid level checks are not

required; therefore the transmission has no

dipstick. An authorized dealer can check your

transmission fluid level using special service tools.

If you notice fluid leakage or transmission

malfunction, visit an authorized dealer

immediately to have the transmission fluid level

checked. Operating the vehicle with an improper

fluid level can cause severe transmission damage.

Fluid And Filter Changes

Under normal operating conditions, the fluid

installed at the factory will provide satisfactory

lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.

However, change the fluid and filter if the fluid

becomes contaminated (with water, etc.), or if the

transmission is disassembled for any reason.
