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 ani-
mals 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.
Checking Coolant Level — 6.4L Engine
The level of the coolant in the pressurized coolant
bottle should be between the “MIN” and “MAX” range
on the bottle when the engine is cold.
The radiator normally remains completely full, so there
is no need to remove the cap unless checking for cool-
ant freeze point or replacing engine coolant (anti-
freeze). Advise your service attendant of this. 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 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 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.
•
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 mini-
mum of 50% OAT coolant (conforming to MS.90032)
and distilled water for proper corrosion protection of
your engine which contains aluminum components.
•
Make sure that the coolant expansion bottle over-
flow 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 necessary, install
ONLY the correct type thermostat. Other designs
may result in unsatisfactory engine cooling perfor-
mance, poor gas mileage, and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Service and Warranty Handbook (Auto
Biography)” 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 pos-
sible brake damage. You would not have your full
braking capacity in an emergency.
Fluid Level Check — Brake Master
Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service or immedi-
ately if the Brake System Warning Light indicates sys-
tem failure.
If necessary, add fluid to bring level within the desig-
nated marks on the side of the reservoir of the brake
master cylinder. Be sure to clean the top of the master
cylinder area before removing cap.
With disc brakes the fluid level can be expected to fall
as the brake linings wear. However, an unexpected drop
in fluid level may be caused by a leak and a system
check should be conducted.
