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 64.
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.
