SERVICING AND MAINTENANCE 437
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 coolant freeze
point or replacing engine coolant (antifreeze). 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
(antifreeze) 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 normally a result of mois-
ture from rain, snow, or high humidity accumulating on the
radiator and being vaporized 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 (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.

• If frequent engine coolant (antifreeze) additions are required, the cooling system should be pressure tested for leaks.

• Maintain engine coolant (antifreeze) concentration at a minimum 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 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 oper -
ation. If replacement is ever necessary, install ONLY the
correct type thermostat. Other designs may result in unsat -
isfactory engine coolant (antifreeze) performance, poor
gas mileage, and increased emissions.

TECHNICAL SPECIFICATIONS 485
CAUTION!
• Mixing of engine coolant (antifreeze) other than speci -
fied Organic Additive Technology (OAT) engine
coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive
Technology (OAT) engine coolant is different and
should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any
“globally compatible” coolant (antifreeze). If a
non-OAT engine coolant (antifreeze) 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 (antifreeze) products. Do not use additional rust inhib -
itors or antirust products, as they may not be compat -
ible with the radiator engine coolant and may plug the
radiator.
• This vehicle has not been designed for use with propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (anti -
freeze) is not recommended.
