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 radiator 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
SERVICING AND MAINTENANCE
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) 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 is changed for low temperature
capability, you must also change the coolant for the
Electric/Battery systems page 64.
Ú
Check the engine cooling system hoses for brittle 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.
