SERVICING AND MAINTENANCE 323
Cooling System
Coolant Checks
Check the engine coolant (antifreeze)
protection every 12 months (before the onset of
fre
ezing 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
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 cooling system hoses for
bri
ttle rubber, cracking, tears, cuts, and
tightness 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
coo
lant 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 (antifreeze) is dirty or
con
tains visible sediment, have an authorized
dealer clean and flush with OAT coolant
(antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in this section
for
the proper maintenance intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
NOTE:
Mixing of engine coolant (antifreeze), other
than specified 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 authorized dealer as soon
as possible.
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 automat-
ically and may start at any time, whether
the
engine is running or not.
When working near the radiator cooling fan,
disconnect 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.
