Overheated Engine
Protection
Operating Mode
If an overheated engine conditionexists and the ENGINE POWER ISREDUCED message displays, anoverheat protection mode whichalternates firing groups of cylindershelps to prevent engine damage. Inthis mode, a loss in power andengine performance will be noticed.This operating mode allows thevehicle to be driven to a safe placein an emergency. Driving extendeddistances and/or towing a trailer inthe overheat protection modeshould be avoided.
Caution
After driving in the overheated
engine protection operating
mode, the engine oil will be
severely degraded. Any repairs
performed before the engine is
cool may cause engine damage.
Allow the engine to cool before

Caution (Continued)
attempting any repair. Repair the
cause of coolant loss, change the
oil, and reset the oil life system.
SeeEngine Oil0359.
Engine Fan
If the vehicle has a clutched enginecooling fan, when the clutch isengaged, the fan spins faster toprovide more air to cool the engine.In most everyday driving conditions,the fan is spinning slower and theclutch is not fully engaged. Thisimproves fuel economy and reducesfan noise. Under heavy vehicleloading, trailer towing, and/or highoutside temperatures, the fan speedincreases as the clutch more fullyengages, so an increase in fannoise may be heard. This is normaland should not be mistaken as thetransmission slipping or makingextra shifts. It is merely the coolingsystem functioning properly. The fanwill slow down when additionalcooling is not required and theclutch disengages.
This fan noise may also be heardwhen starting the engine. It will goaway as the fan clutch partiallydisengages.
If the vehicle has electric coolingfan(s), the fans may be heardspinning at low speed during mosteveryday driving. The fans may turnoff if no cooling is required. Underheavy vehicle loading, trailer towing,high outside temperatures,or operation of the air conditioningsystem, the fans may change tohigh speed and an increase in fannoise may be heard. This is normaland indicates that the coolingsystem is functioning properly. Thefans will change to low speed whenadditional cooling is no longerrequired.
The electric engine cooling fansmay run after the engine has beenturned. off. This is normal and noservice is required.
