WHAT TO DO IF...

Check Engine Lamp TurnsOn

Check Engine Lamp - Turns on whena problem exists, but the vehicle canstill be safely driven. Vehicle should beserviced to correct the problem but thesituation should not be considered anemergency.

Engine is Overheating

CAUTIONThe cooling system may over-heat if the engine coolant is at theminimum level. A sudden loss ofcoolant, caused by a split hoseor broken hose clamp could alsolead to an overheat condition. Al-ways inspect to ensure hoses andclamps are not cracked, worn, orloose. Failure to comply may resultin equipment or property damage.

NOTEThe system may also temporarilyoverheat during severe operatingconditions such as:

• Climbing a hill on a hot day.

• Stopping after high-speed/high-load driving.

• Debris blocking air flowthrough the cooling module(radiator).

If the engine coolant temperaturewarning lamp comes on and theaudible alarm sounds showing anoverheat condition, or if you have anyother reason to suspect the enginemay be overheating, DO NOT TURNOFF THE ENGINE unless a low waterwarning device indicates a loss ofcoolant. Follow these steps:

• Reduce engine speed, orstop. When stopped, place the

transmission in neutral (N) and setthe parking brake. “See the vehicleoperator's manual for instructionson transmission shifting andparking brake information.”

• Check to ensure that the oilpressure gauge reads normal.

• Increase the engine speed to1,100 to 1,200 RPM maximum fortwo to three minutes.

• Monitor the engine temperature.After the temperature returnsto normal, allow the engine toidle three to five minutes beforeshutting it off. This allows theengine to cool gradually anduniformly.

• If the overheating came fromsevere operating conditions, thetemperature should have cooledby this time.

• Be sure the vehicle is parked onlevel ground or the readings maybe incorrect. Check the coolantlevel at the cooling module surgetank.

WARNING!

To reduce the chance of per-sonal injury and/or vehicle damagecaused by engine overheating,never leave the engine idling whenthe vehicle is unattended. If the en-gine overheats, immediate actionis required to correct the condition.Continued unattended operationof the engine, even for a shorttime, may result in serious enginedamage or a fire. Failure to com-ply may result in death, personalinjury, equipment or property dam-age.

WARNING!

Removing the fill cap on a hot en-gine can cause scalding coolantto spray out and burn you badly.If the engine has been in opera-tion within the previous 30minutes,be very careful in removing the fillcap. Protect face, hands, and armsagainst escaping fluid and steamby covering the cap with a large,thick rag. DO NOT try to removeit until the surge tank cools downor if you see any steam or coolantescaping. In any situation, removethe cap very slowly and carefully.Be ready to back off if any steamor coolant begins to escape. Seethe vehicle operator's manual forinstructions on checking and fillingthe cooling module surge tank.

WHAT TO DO IF...

CAUTION

Prolonged periods of idling afterthe engine has reached operat-ing temperatures can decreaseengine temperature and couldcause engine damage from inad-equate lubrication. The normaltorsional vibrations generated canalso cause transmission wear. Anidle shutdown feature, availableon PACCAR engines, can be pro-grammed to shut the engine downafter a period of low idle operationwith no driver activity. A flashingwarning lamp will inform the driverof an impending shutdown. Failureto comply may result in equipmentor property damage.

CAUTION

If the truck is equipped with powertake off (PTO) equipment, the en-gine shutdown system can be de-activated when the PTO is oper-ational; however, engine idle pe-riods should not exceed five min-utes whenever possible. Failure tocomply may result in equipment orproperty damage.

• The words “WARNING” or“CHECK ENGINE” spelled out.

• A symbol of an engine, similar tothe graphic illustrated.

The “Check Engine” lamp is locatedon the face of the tachometer andilluminates when a problem exists,but the vehicle can still be safelydriven. The vehicle should be servicedto correct the problem, but thesituation should not be considered an

emergency. The “Check Engine” lampwill activate for several reasons. Theseinclude but are not limited to: Water infuel and Diesel Particulate Filter (DPF)regeneration required.

The “Check Engine” lamp is to flash for30 seconds at key ON when one of thefollowing occurs. This flashing functionis referred to as the “maintenance”lamp. The “maintenance” lamp couldflash for any of the following reasons:

• Maintenance required (if theMaintenance Monitor is enabled).

• Water-in-fuel is detected.

• Coolant level is low.

Malfunction Indicator Lamp

The “Malfunction Indicator Lamp” (MIL)illuminates when an engine emissionsfailure has occurred. The vehiclecan be safely driven but should beserviced to correct the problem. Thesituation should not be considered anemergency. In some cases, the MILwill activate in conjunction with the“High Exhaust System Temperature,”DPF and “Diesel Exhaust Fluid” (DEF)warning lamps.

Engine Operating RangeGeneral Information

CAUTION

Operating the engine at full throttlebelow peak torque will shorten en-gine life to overhaul, can cause se-rious engine damage, and is con-sidered engine abuse. DO NOToperate the engine at full throttleoperation below peak torque RPMfor more than 30 seconds. Failureto comply may result in equipmentor property damage.

3-6 Y53-1183-1B1 (12/2014)

3

OPERATING INSTRUCTIONS

PACCAR engines are designed tooperate at full throttle under momentaryconditions down to peak torque enginespeed. This is consistent withrecommended operating practices.

CAUTION

Operating the engine beyondthe maximum engine speed cancause severe engine damage.Use proper operating techniquesfor the vehicle to prevent engineoverspeed. The maximum enginespeed specification is listed in the“General Engine Specifications”on page 5-13. Failure to complymay result in equipment or prop-erty damage.

CAUTION

DO NOT idle the engine for ex-cessively long periods. Long pe-riods of idling, more than 10 min-utes, can cause poor engine per-formance.

NOTEFor applications with highidle-time, to help reduce soot load-ing in the aftertreatment system,avoid long periods of idling. If idlingis required, increase idle-speedusing the cruise control function.

Engine Braking System

Variable Geometry Turbo (VGT)Brake System General Information

1. Sliding Nozzle

This engine may be equipped with avariable geometry turbocharger (VGT)with an exhaust brake feature. Thisfeature allows the variable geometryturbocharger to act as an exhaustbrake by retarding the speed of theengine to provide additional vehiclebraking power and extend the life of thevehicle service brakes. The ON/OFF

(12/2014) Y53-1183-1B1 3-7

3

OPERATING INSTRUCTIONS

function is controlled by a switchlocated on the dash of the vehicle. Theengine (VGT) exhaust brake worksby retarding engine speed by creatinghigh exhaust back pressure. This backpressure is obtained by restrictingairflow through the turbine housingof the turbocharger. This restrictionthrough the turbine housingis createdthrough positioning of the slidingnozzle (1) located internally to theturbocharger. the position of the slidingnozzle is controlled by the engineelectronic control module (ECM). Thisoption may not be available on yourvehicle.

WARNING!

The exhaust brake is not intendedas the primary brake for the vehi-cle, nor is it an emergency brake.The service brakes must be usedin an emergency. Relying solely onthe exhaust brake to stop the ve-hicle in an emergency could causean accident and lead to personalinjury. The exhaust brake onlyhelps the service brakes by usingpressure to slow the drive train.You must use the service brakesfor quick or emergency stops. Fail-ure to comply may result in death,personal injury, equipment or prop-erty damage.

WARNING!

DO NOT use the exhaust brakewhen operating on surface withpoor traction (such as wet, icy orsnow covered roads). Retarderscan cause the wheels to skid ona slippery surface. You could losecontrol of the vehicle and jacknife ifthe wheels begin to skid, resultingin an accident. Failure to com-ply may result in death, personalinjury, equipment or property dam-age.

3-8 Y53-1183-1B1 (12/2014)

OPERATING INSTRUCTIONS

WARNING!

DO NOT use an exhaust brakewhen driving bobtail or with an un-loaded trailer. There may not beenough weight on the rear axle toprovide traction. This could causea loss of control and jackknife re-sulting in an injury accident. Makesure the exhaust brake is switched“OFF” when bobtailing or with anunloaded trailer. Failure to com-ply may result in death, personalinjury, equipment or property dam-age.

NOTEWhen the engine (VGT) exhaustbrake switch is in the “ON” posi-tion, the engine's electronic controlmodule (ECM) monitors inputs(such as accelerator pedal positionand engine speed). From these in-puts, the ECM determines when toenable the engine (VGT) exhaustbrake feature when the properbraking conditions are present.

Other features/switches like cruisecontrol, can also affect when theengine (VGT) exhaust brake activates.For more information on how theengine (VGT) exhaust brake functions,refer to vehicle operation manual orcontact a PACCAR Authorized RepairLocation.

WARNING!

To reduce the possibility of per-sonal injury or property damage,always be prepared to use the ve-hicle service brakes for emergencystopping. The safe control speedof a vehicle will vary with the sizeof the load, the type of load, thegrade, and the road conditions.Failure to comply may result indeath, personal injury, equipmentor property damage.

NOTEThe exhaust brake can only be ac-tivated when the accelerator pedalis at its “low-idle” position. With thethrottle at “low-idle” position, fuel-ing commands to the cylinders willnot detract from the braking powerof the brake system.

(12/2014) Y53-1183-1B1 3-9

3

OPERATING INSTRUCTIONS

NOTEThe engine (VGT) exhaust brakeis designed to assist the vehicle'sservice brakes when slowing thevehicle to a stop.

Vehicle service brakes must always beused. The engine brake is not intendedto be used as the primary brake of thevehicle, nor is it an emergency brake.The engine retarder only helps theservice brakes by using pressure toslow the drivetrain. Use the servicebrakes for quick stops.

CAUTIONExceeding governed engine speedcan cause engine damage. Oper-ating the engine beyond the maxi-mum engine speed may cause se-rious engine damage and is con-sidered engine abuse. Use the en-gine and vehicle braking systemsto control engine speed.

The optimum braking power of theengine (VGT) exhaust brake is reachedat rated engine speed. Correct gearselection, therefore, is critical.

Typically, on vehicles equipped withautomatic transmissions, the engineelectronic control module (ECM) andthe transmission will determine thecorrect gear selection.

OPERATING INSTRUCTIONS

NOTEFor engines equipped with theengine warm-up protection fea-ture; this feature limits enginespeed and torque following enginestart-up until sufficient oil pressureis available to the engine compo-nents. This feature reduces therisk of engine part damage dueto operating at engine speeds toohigh or loads before adequate oilpressure is achieved.

Some engines are equipped with a“Fast-Idle Warm-Up” feature. Whenenabled, this feature elevates the idlespeed of the engine in cold ambientconditions, in order to shorten the timenecessary to warm up the engine.When the idle speed is elevated, theengine noise may change, this isnormal. To bring the engine back tolow idle speed:

• For vehicles equipped with amanual transmission and clutchswitch: Depress the clutch pedal.

• For vehicles equipped with a brakeswitch: Depress the service brakepedal.

• Depress the accelerator pedal.

For more information on the “Fast-IdleWarm-Up” feature, contact a PACCARauthorized repair location.

Cold Weather StartingGeneral Information

CAUTION

CAUTION

The use of starting aids, such asether, may result in damage to theengine and aftertreatment system.

If an engine must idle for an extendedperiod of time, it should be done ata fast idle (1,000 RPM maximum) atcoolant temperatures below 150°F(70°C).

For coolant temperatures below 150°F(70°C), use a low gear and driveat moderate engine speed until theengine coolant has reached operatingtemperature. DO NOT let the engineidle longer than necessary.

CAUTION

DO NOT operate the engine at lowidle for long periods with enginecoolant temperature below theminimum specification in “CoolingSystem” on page 5-14. This canresult in the following:

• Fuel dilution of the lubricatingoil

• Carbon buildup in thecombustion chamber

• Sticking of the valves in thecylinder head

• Reduced performance

• Damage to aftertreatmentcomponents

Cold Weather

It is possible to operate engines inextremely cold environments if theyare properly prepared and maintained.Satisfactory performance of anengine in low ambient temperatureconditions requires modification ofthe engine, surrounding equipment,operating practices and maintenanceprocedures.

The correct engine coolant, lubricatingoil and fuels must be used for the coldweather range in which the engine isbeing operated. See the “MaintenanceSection” on page 5-3 for these criticalengine fluids recommendations andspecifications.

OPERATING INSTRUCTIONS

Continuous operation with enginecoolant temperature above or belowthe engine coolant temperaturespecifications listed in “CoolingSystem” on page 5-14 can damagethe engine.

Engine ShutdownBefore Stopping the Engine

NOTEDO NOT shut off the engine im-mediately. A hot engine stores agreat amount of heat and it doesnot cool down immediately after itis shut off. Always cool the enginedown before shutting it off. You willgreatly increase its service life.

Idle the engine at 1,000 RPM for fourminutes. Then low idle for 30 secondsbefore shutdown. This will allowcirculating coolant and lubricating oilto carry heat away from the cylinderhead, valves, pistons, cylinder liners,turbocharger, and bearings. This wayyou can prevent engine damage thatmay result from uneven cooling.

NOTEFor engines equipped with an elec-tronic control module (ECM) en-sure the key switch is turned OFFfor a minimum of 70 seconds priorto disconnecting the continuous(unswitched) battery power supply.If the unswitched battery powersupply is disconnected in less than70 seconds after the key switchis turned OFF, active fault codesand incorrect ECM information canoccur.

Turn the ignition switch to the OFFposition. If the engine does notshut down, refer to “TroubleshootingSymptom” (Section TS) in theappropriate maintenance manual.

DO NOT use an engine brakewhen driving bobtail or with an un-loaded trailer. There may not beenough weight on the rear axle toprovide traction. This could causea loss of control and jackknife re-sulting in an injury accident. Makesure the engine brake is switched“OFF” when bobtailing or with anunloaded trailer. Failure to com-ply may result in death, personalinjury, equipment or property dam-age.

To reduce vehicle speed, put theengine brake “ON/OFF” switch in the“ON” position. Remove your foot fromthe accelerator pedal and clutch pedal.The engine brakes will immediatelybegin to operate, slowing the vehicle.

For operation on dry and relatively flatsurfaces, when greater retarding poweris not required, put the two-positionselector switch in the “LOW” position.

For operation on dry pavement whenmaximum retarding power is required,put the two-position selector switch inthe “HI” position.

Tips for Operation onGradeswith Dry Pavement

WARNING!

The engine brake is not intendedas the primary brake for the vehi-cle, nor is it an emergency brake.The service brakes must be usedin an emergency. Relying solely onthe engine brake to stop the vehi-cle in an emergency could causean accident and lead to personalinjury. The engine brake only helpsthe service brakes by using pres-sure to slow the drive train. Youmust use the service brakes forquick or emergency stops.

Tips for Operation on SlickRoads

WARNING!

To reduce the possibility of per-sonal injury or property damage,always allow for extra distancebetween your vehicle and otherobjects when using the servicebrakes or engine brakes on slickroads.

The operation of any vehicle is difficultto predict on slick roads. The first 10to 15 minutes of rainfall are the mostdangerous, as road dirt and oil mixedwith rain create a very slippery surface.

WARNING!

DO NOT operate the engine brakewhen driving/operating your ve-hicle bobtail or with a loaded orunloaded trailer on road surfaceswith poor traction (wet, icy, or snowcovered roads) or in heavy traffic.Braking caused by the normal op-eration of the engine brake couldcause you to lose control of the ve-hicle resulting in an injury accident.Failure to comply may result indeath, personal injury, equipmentor property damage.

When driving on slick roads, start withthe “ON/OFF” switch in the “OFF”position and the two-position selectorswitch in the “LOW” position.

If your tractor is equipped with atwin-screw rear axle, position thepower divider switch in the “unlocked”position.

Remove your foot from the acceleratorpedal to make sure the vehicle willmaintain traction with the retardingpower of the engine alone.

OPERATING INSTRUCTIONS

If the vehicle drive wheels begin to skidor if there is a fishtailing motion, DONOT activate the engine brakes.

If traction is maintained using theretarding power of the engine aloneand more braking power is required,switch the two-position selector switchto the “LOW” position and activatethe engine brakes by switching the“ON/OFF” switch to the “ON” position.

If the vehicle’s drive wheels begin toskid or there is a fishtailing motion,switch the “ON/OFF” switch to the“OFF” position.

If traction is maintained when theengine brakes are activated and morebraking power is required, move thetwo-position selector switch to the “HI”position.

Again, if the vehicle has lost traction orif there is a fishtailing motion, switchthe “ON/OFF” switch to the “OFF”position. DO NOT attempt to use theengine brakes in the “HI” position.

NOTEPACCAR recommends that thecetane number of diesel fuel bea minimum of 45 for engines thatare expected to operate at tem-peratures below 32°F (0°C) and aminimum of 42 for engines that areoperated at temperatures above32°F (0°C).

Ultra-low sulfur diesel fuel is definedas diesel fuel not exceeding 0.0015(15 ppm) mass percent sulfur content(ultra-low diesel fuel is also defined byASTM S-15). There are NO acceptablesubstitutes.

PACCAR recommends the use ofASTM number 2D fuel. The use ofnumber 2 diesel fuel will result inoptimum engine performance.

At operating temperatures below 32°F(0°C), acceptable performance can be

obtained by using blends of number2D and number 1D.

Using diesel fuel with alower-than-recommended cetanenumber can cause hard starting, pooridle and excessive white smoke. Tomaintain satisfactory operation at lowambient temperatures, it is importantto specify diesel fuel of the correctcetane number.

PACCAR requires all permissiblefuels to have adequate fuel lubricity.Lubricity can be determined by ASTM,specification D6079, ISO 12156, highfrequency reciprocating rig (HFRR) inwhich the fuel must have a wear scardiameter of 0.02 in. (0.5 mm) or less.

The use of ultra-low sulfer diesel(ULSD) fuel is required for this enginein order to meet emission regulationsand to prevent damage to the engineand exhaust system. The use ofother grades of diesel fuels other than

ULSD fuel will be considered a use ofincorrect fuel for the engine. PACCARis not responsible for failures causedby the use of incorrect fuel, oil or DEFor by water, dirt or other containmentsin the fuel or DEF.

Warranty and the Use ofBiodiesel Fuel

PACCAR Inc. approves the use ofbiodiesel fuel blends up to 20 percentby volume in diesel fuel providing thatthe following conditions are meet:

• The biodiesel used in the blendmeets ASTM Standard D6751 orEN 14214 specifications.

• The biodiesel used in the blendis sourced from a BQ-9000Accredited Producer.

• The finished blend meets the fuelproperties of the ASTM StandardD975 (up to B5 blend) or D7467(B6 to B20 blend).

• The engine oil and oil filter arechanged at 40,000 miles/64,000km (or six months).

• The fuel filter is changed every25,000 miles/40,000 km.

The use of approved biodiesel fueldoes not affect the PACCAR enginewarranty. Failures caused by the use ofnon-approved biodiesel fuels or otherfuel additives that are of unacceptablequality or DO NOT meet specifiedindustry standards are not consideredas defects of parts or workmanshipby PACCAR and therefore will notbe covered by the PACCAR enginewarranty.

PACCAR recommends that customersintending to use biodiesel blendsbecome familiar with the additionalhandling considerations of these fuelssuch as ageing, metal compatibilityand tendency to absorb water. Pleasereference the fuel supplier’s technicalinformation or industry guidelines suchas the American Trucking AssociationTruck Maintenance Council documentRP 357.

In particular, operators should beaware that biodiesel blends aremore prone to cold flow (gelling) andfilter plugging issues compared toconventional diesel fuel. If vehiclesare expected to be operated intemperatures below freezing, careshould be taken to ensure that both thebiodiesel fuel used and the appropriatevehicle fuel system accessory heatersare utilized.

Operators should also be aware thatbiodiesel energy content (by volume)is lower than diesel which can reducefuel economy by up to two percent.

Lubricating OilRecommendations andSpecificationsGeneral Information

CAUTION

Extending the oil and filter changeinterval beyond the recommenda-tions will decrease the engine lifedue to factors such as corrosion,deposits, and wear. Engine oilfilters capture dirt and remove de-posits from the oil to prolong thelife of internal moving components.Follow the oil and filter changeintervals as recommended in thissection of the manual. Failure tocomply may result in equipment orproperty damage.

The use of quality engine lubricatingoils, combined with appropriate oildrain and filter change intervals, is acritical factor in maintaining engineperformance and durability. Extendingthe oil and filter change interval beyondthe recommendations will decreaseengine life due to factors such ascorrosion, deposits, and wear. Referto “Oil Drain Intervals” on page 5-11to determine which oil drain interval touse for an application.

NOTEIt is the owners responsibility tocorrectly follow lubricating oil rec-ommendations. If recommenda-tions are ignored, the engine war-ranty could be affected.

NOTEA lubricating oil that meets theAmerican Petroleum Institute(API) performance classificationCJ-4/SL may not meet the CES20081 requirement. Always makesure the lubricating oil used meetsthe CES 20081 requirement inaddition to the API performanceclassification CJ-4/SL.

PACCAR recommends the use ofhigh-quality SAE 10W30 API CJ-4heavy-duty engine oil.

The primary PACCARrecommendation is for the use of10W30 multigrade lubricating oilfor normal operation at ambienttemperatures above 5°F (-15°C).For ambient temperatures below5°F (-15°C) SAE 5W30 may beused, provided it meets API CJ-4oil specifications and biodiesel or

biodiesel blended fuel is not used asfuel for the engine. Using a multigradeoil helps improve engine cranking inlow-temperature conditions, reducesdeposit formation and increasesengine durability.

Use of “synthetic engine oils” (thosemade with API group 3 or group 4base stocks) is permitted subject tothe same performance and viscositylimitations of petroleum (mineral)based engine oils. The same oilchange intervals must be appliedto synthetic oils that are applied topetroleum (mineral) based engine oils.

1. All seasons2. All seasons3. Winter conditions4. Winter conditions5. Arctic conditions

While the preferred viscosity grade is10W-30, lower viscosity multigrade oilscan be used in colder climates. Seethe accompanying chart. Any viscositygrade lower than 10W-30 must stillmeet CES 20081.

Synthetic engine oils, API GroupIII and Group IV basestocks, are

MAINTENANCE SPECIFICATIONS

recommended for use in PACCARengines operating in ambienttemperature conditions consistentlybelow -13°F (- 25°C). Synthetic 0W-30oils that meet the requirements of APIGroup III or Group IV basestocks,can be used in operations where theambient temperature never exceeds32°F (0°C). Multiviscosity oils rated0W-30 DO NOT offer the same level ofprotection against fuel dilution as dohigher multigrade oils. Higher cylinderwear can be experienced when using0W-30 oils in high-load situations.

As these oils have directionally thinneroil films than 10W-30 oils, top-qualityFleetguard® filters must be usedabove 70°F (20°C). Some oil suppliersmight claim better fuel economy forthese oils. PACCAR can neitherapprove nor disapprove any productnot manufactured by PACCAR. Theseclaims are between the customer andoil supplier. Obtain a commitment fromthe oil supplier that the oil will give

satisfactory performance in PACCARengines or DO NOT use the oil.

New Engine Break-In Oils

PACCAR does not approve the use ofspecial “break-in” engine lubricatingoils for new or rebuilt PACCARengines. It is recommended to usethe same lubricating oil for enginebreak-in that will be used during normaloperation.

CAUTION

A sulfated ash limit of 1.85 percenthas been placed on all engine lu-bricating oils recommended for usein PACCAR engines. Higher ashoils can cause valve and/or pis-ton damage and lead to excessiveoil consumption. Failure to complymay result in equipment damage.

Aftermarket Oil Additive Usage

PACCAR does not recommend the useof aftermarket oil additives. Today'shigh-quality engine lubricating oils arevery sophisticated. Most oils alreadycontain precise amounts of additivesblended into the lubricating oil to meetstringent performance requirements.

These furnished oils meet performancecharacteristics that conform tothe lubricant industry standards.Aftermarket lubricating oil additives arenot necessary to enhance engine oilperformance and in some cases canreduce the furnished oil's capability toprotect the engine.

Inspection of the Engine OilLevel

NOTEIt takes approximately 15 minutesfor all the oil to run into the sumpwhen the engine is ‘warm.’ If thelevel is checked immediately afterswitching off the engine, the dip-stick will show a low oil level.

After the engine is shut off it will takeat least 15 minutes for all the engineoil to return to the sump. If the level ischecked immediately after switchingoff the engine, the dipstick will showa low oil level.

1. Engine coolant should be at orabove the operating temperatureof 180°F (82°C).

Coolant Recommendationsand Specifications

The cooling system in your vehiclewas factory filled with Extended LifeCoolant (ELC) that meets or exceedsall ASTM D 6210 requirements.PACCAR recommends only using a50/50 mixture of distilled water andELC when cooling system serviceis required. A 50/50 mixture of ELCand distilled water will provide freezeprotection down to -34°F (-36.7°C),which is adequate for most locationsin North America. For extremely coldoperating conditions, a 60/40 mixture(coolant/water ratio) can be used toprovide freeze protection down to-62°F (-52.2°C).

Good-quality water is importantfor cooling system performance.Excessive levels of calcium andmagnesium contribute to scalingproblems, and excessive levels of

chlorides and sulfates cause coolingsystem corrosion.

Water Quality

CalcuimMagnesium(hardness)

Maximum 170ppm as (CaCO3 +

MgCO3)

Chloride 40 ppm as (Cl)

Sulfur 100 ppm as (SO4)

Fully formulated antifreeze must bemixed with good quality water at a50/50 ratio (40- to 60-percent workingrange). A 50/50 mixture of antifreezeand water gives a -33°F (-36°C)freezing point and a 226°F (108°C)boiling point, which is adequate forlocations in North America. The actuallowest freezing point of ethylene glycolantifreeze is at 68 percent. Usinghigher concentrations of antifreeze willraise the freezing point of the solution,increase the likelihood of overheatingand increase the possibility of a silicagel problem.

PACCAR vehicle engine-coolingsystems are filled with fully formulatedELC.

PACCAR recommends the use offully formulated ELC that meets therequirements of CES 14603 for top offand service.
