ENGINE COOLANT CHECK -
6.7L DIESEL
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling systemis under pressure. Steam and hot liquidcan come out forcefully when you loosenthe cap slightly.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 325).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -30°F (-34°C) and -34°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.

Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Cooling System Capacityand Specification (page 302). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.
Note: Coolants marketed for all makes andmodels may not be approved to ourspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.

POWER STEERING FLUID
CHECK
Check the power steering fluid. SeeScheduled Maintenance (page 325). Ifadding fluid is necessary, use onlyMERCON LV ATF
Check the fluid level when it is at ambienttemperature.
1.Check the fluid level in the reservoir. Itshould be between the MIN and MAXrange. Do not add fluid if the level iswithin this range.
2.If the fluid level is low, add fluid to bringthe fluid level up to between the MINand MAX range.
3.Switch the engine on.
4.While the engine idles, turn the steeringwheel left and right several times.
5.Switch the engine off.
6.Recheck the fluid level in the reservoir.Do not add fluid if the level is betweenthe MIN and MAX range.
7.If the fluid is low, add the proper typeof fluid in small amounts, continuouslychecking the level until it is betweenthe MIN and MAX range. SeeHydraulic Power Steering FluidCapacity and Specification (page312). Be sure to put the cap back on thereservoir.
CHANGING THE 12V BATTERY
WARNING: This vehicle may beequipped with more than one battery,removal of cable from only one batterydoes not disconnect the vehicleelectrical system. Be sure to disconnectcables from all batteries whendisconnecting power. Failure to do somay cause serious personal injury orproperty damage.

*Traction: The traction grades,from highest to lowest are AA, A,B, and C. The grades represent thetire's ability to stop on wetpavement as measured undercontrolled conditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.
*Temperature: The temperaturegrades are A (the highest), B andC, representing the tire'sresistance to the generation ofheat and its ability to dissipateheat when tested under controlledconditions on a specified indoorlaboratory test wheel.
M.Maximum InflationPressure: Indicates the tiremanufacturers' maximumpermissible pressure or thepressure at which the maximumload can be carried by the tire. Thispressure is normally higher thanthe vehicle manufacturer'srecommended cold inflationpressure which can be found onthe Safety ComplianceCertification Label. The coldinflation pressure should never beset lower than the recommendedpressure on the vehicle label.
