manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals before

WARNING!
Turn vehicle off and disconnect the fan motor lead

before working near the radiator cooling fan.
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 radi-
ator or coolant bottle is hot.
Do not put your hands, tools, clothing, and

jewelry near the radiator cooling fan. The fan
may start at any time, whether the ignition is
on or off.
Cooling Fan Warning Label
This vehicle is equipped with an electric cooling
fan mounted behind the radiator that starts
automatically, and may start at any time. Your
vehicle may determine the fan needs to start and
to run if vehicle coolant is too hot, or if the ambient
air temperature is too high. Even after the vehicle
is turned off, the fan may start without warning and
run for several minutes. Be aware of this if you are
working in the engine compartment. Always keep
fingers and tools away from the fan blades.
The radiator fan and surrounding components
must be serviced by an authorized dealer.
Engine 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, 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 for any
accumulation of bugs, leaves, etc. If dirty, clean by
gently spraying water from a garden hose vertically
down the face of the condenser.
NOTE:
If the engine coolant protection is changed, you
must also adjust the coolant protection for the
Electric/Battery Coolant systems Ú page 55.
