SERVICING AND MAINTENANCE
the vehicle, turn off the engine and allow it to cool. Ser-
vice, including a tune-up to manufacturer's specifica-
tions, should be obtained immediately.
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 mode. The fan is temperature controlled
and can start at any time the ignition is in the ON
mode.
Coolant Checks
Check the engine, battery (if equipped), intercooler
(if equipped), and Motor Generator Unit (MGU)
(if equipped) coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine, battery (if equipped), inter-
cooler (if equipped), and MGU (if equipped) coolant is
dirty or rusty in appearance, the system should be
drained, flushed and refilled with fresh OAT coolant
(conforming to MS.90032) by an authorized 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 condenser (if
equipped) or the back of the radiator core.
Check the engine, battery (if equipped), intercooler
(if equipped), and MGU (if equipped) cooling system
hoses for brittle rubber, cracking, tears, cuts, and tight-
ness of the connection 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
NOTE:
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 295 for gasoline engines or
diesel engines.
Selection Of Coolant
For further information
page 361.
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 (antifreeze) products. Do not use additional
rust inhibitors or anti-rust 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 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.
