Service
All vehicles have a label underhoodthat identifies the refrigerant used inthe vehicle. The refrigerant systemshould only be serviced by trainedand certified technicians. The airconditioning evaporator shouldnever be repaired or replaced byone from a salvage vehicle.It should only be replaced by a newevaporator to ensure proper andsafe operation.
During service, all refrigerantsshould be reclaimed with properequipment. Venting refrigerantsdirectly to the atmosphere is harmfulto the environment and may alsocreate unsafe conditions based oninhalation, combustion, frostbite,or other health-based concerns.

Warning (Continued)
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam is Coming from
the Engine Compartment
The ENGINE OVERHEATED STOPENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage, along with a low coolantcondition, can indicate a seriousproblem.
If there is an engine overheatwarning, but no steam is seen orheard, the problem may not be tooserious. Sometimes the engine canget a little too hot when the vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.To w s a t r a i l e r ; s e eTr a i l e rTo w i n g0318.
If the ENGINE OVERHEATEDSTOP ENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage appears with no sign ofsteam, try this for a minute or so:
1. Turn the air conditioning off.
2. Turn the heater on to thehighest temperature and to thehighest fan speed. Open thewindows as necessary.
3. When it is safe to do so, pull offthe road, shift to P (Park) orN(Neutral)andlettheengine idle.
If the temperature overheat gauge isno longer in the overheat zone or anoverheat warning no longer
displays, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safevehicle distance from the vehicle infront. If the warning does not comeback on, continue to drive normallyand have the cooling systemchecked for proper fill and function.
If the warning continues, pull over,stop, and park the vehicleright away.
If there is still no sign of steam andthe vehicle is equipped with anengine driven cooling fan, pushdown the accelerator until theengine speed is about twice as fastas normal idle speed for at leastfive minutes while the vehicle isparked. If the warning is still there,turn off the engine and get everyoneout of the vehicle until it cools down.
If there is no sign of steam, idle theengine for five minutes whileparked. If the warning is stilldisplayed, turn off the engine until itcools down.

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
(Continued)
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.

(2) Tire Width:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio:Atwo-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 75, as shown in
item 3 of the light truck
(LT-Metric) tire illustration, it
would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code:Aletter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Load Range:Load Range.
(7) Service Description:The
service description indicates the
load index and speed rating of a
tire. If two numbers are given as
in the example, 120/116, then
this represents the load index for
single versus dual wheel usage
(single/dual). The speed rating is
the maximum speed a tire is
certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio:The relationship
of a tire's height to its width.
Belt:Arubbercoatedlayerof
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire:Apneumatictire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. SeeTire
Pressure0405.
Curb Weight:The weight of a
motor vehicle with standard and
optional equipment including the
