To minimize the possibility of catalytic converter
damage:
•
Do not interrupt the ignition when the transmission
is in gear and the vehicle is in motion.
•
Do not try to start the vehicle by pushing or towing
the vehicle.
•
Do not idle the engine with any ignition components
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
COOLING SYSTEM
WARNING!
•
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the
hood, do not open the hood until the radiator has
had time to cool. Never open a cooling system
pressure cap when the radiator or coolant bottle is
hot.
•
Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised.
The fan starts automatically and may start at any
time, whether the engine is running or not.
•
When working near the radiator cooling fan, dis-
connect the fan motor lead or turn the ignition to
the OFF position. The fan is temperature controlled
and can start at any time the ignition is in the ON
position.
Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant is dirty or rusty in
appearance, the system should be drained, flushed,
and refilled with fresh Organic Additive Technology
(OAT) coolant (conforming to MS.90032) by an autho-
rized dealer. Check the front of the A/C condenser
(if equipped) or radiator for any accumulation of bugs,
leaves, etc. If dirty, clean by gently spraying water from
a garden hose vertically down the face of the A/C con-
denser (if equipped) or the back of the radiator core.
Check the engine cooling system hoses for brittle rub-
ber, cracking, tears, cuts, and tightness of the connec-
tion at the coolant recovery bottle and radiator. Inspect
the entire system for leaks. DO NOT REMOVE THE
COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM
IS HOT.
Cooling System — Drain, Flush, And
Refill
Some vehicles require special tools to add coolant prop-
erly. 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 (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (conforming to MS.90032).
For the proper maintenance intervals see
page 247.

For further information page 296.
NOTE:
•
Mixing of engine coolant (antifreeze), other than
specified Organic Additive Technology (OAT) engine
coolant, may result in engine damage and may
decrease corrosion protection. OAT engine coolant is
different and should not be mixed with Hybrid
Organic Additive Technology (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 authorized dealer
as soon as possible.
•
Do not use water alone or alcohol-based engine
coolant products. Do not use additional rust inhibi-
tors or anti-rust products, as they may not be com-
patible with the radiator engine coolant and may
clog the radiator.
•
This vehicle has not been designed for use with pro-
pylene glycol-based engine coolant. Use of propyl-
ene 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 cool-
ant is needed to be added to the system please con-
tact an authorized dealer.
