    Diesel Fuel

    Consult your local fuel distributor for properties of thediesel fuel available in your area.

    In general, diesel fuels are blended to satisfy the lowtemperature requirements of the geographical area inwhich they are marketed.

    Diesel fuels specified to EN 590 or ASTM D975 arerecommended.

    In all cases, the fuel shall meet the followingproperties:

    Cetane number of 40 minimum. Cetane numbergreater than 50 is preferred, especially fortemperatures below -20 C (-4 F) or elevations above1500 m (5000 ft).

    Cold Filter Plugging Point (CFPP) below theexpected low temperature OR Cloud Point at least5 C (9 F) below the expected low temperature.

    Fuel lubricity should pass a minimum of 3100 gramload level as measured by the BOCLE scuffing test.

    Sulfur content:

    Sulfur content should not exceed 0.5%. Sulfurcontent less than 0.05% is preferred.

    If diesel fuel with sulfur content greater than 0.5%sulfur content is used, reduce the service interval forengine oil and filter by 50%.

    DO NOT use diesel fuel with sulfur content greaterthan 1.0%.

    DO NOT mix used engine oil or any other type oflubricant with diesel fuel.

    Bio-Diesel Fuel

    Consult your local fuel distributor for properties of thebio-diesel fuel available in your area.

    Bio-diesel fuels may be used ONLY if the bio-dieselfuel properties meet the latest edition of ASTM PS121,DIN 51606 or equivalent specification.

    It has been found that bio-diesel fuels may improvelubricity in concentrations up to a 5% blend inpetroleum diesel fuel.

    When using a blend of bio-diesel fuel, the engine oillevel must be checked daily when the air temperatureis -10 C (14 F) or lower. If the oil becomes diluted withfuel, shorten oil change intervals accordingly.

    IMPORTANT: Raw pressed vegetable oils are NOTacceptable for use for fuel in anyconcentration in John Deereengines.

    These oils do not burn completely,and will cause engine failure byleaving deposits on injectors and inthe combustion chamber.

    A major environmental benefit of bio-diesel fuel is itsability to biodegrade. This makes proper storage andhandling of bio-diesel fuel especially important. Areasof concern include:

    Quality of new fuel Water content of the fuel Problems due to aging of the fuel

    Potential problems resulting from deficiencies in theabove areas when using bio-diesel fuel inconcentrations above 5% may lead to the followingsymptoms:

    Power loss and deterioration of performance Fuel leakage Corrosion of fuel injection equipment Coked and/or blocked injector nozzles, resulting in

    engine misfire Filter plugging Lacquering and/or seizure of internal components Sludge and sediments Reduced service life of engine components

    DX,FUEL5 1927OCT051/1

    Lubricity of Diesel Fuel

    Most diesel fuels manufactured in the United States,Canada, and the European Union have adequatelubricity to ensure proper operation and durability offuel injection system components. However, dieselfuels manufactured in some areas of the world maylack the necessary lubricity.

    IMPORTANT: Make sure the diesel fuel used inyour machine demonstrates goodlubricity characteristics.

    Fuel lubricity should pass a minimum load level of3100 grams as measured by ASTM D6078 or amaximum scar diameter of 0.45 mm as measured byASTM D6079 or ISO 12156-1.

    If fuel of low or unknown lubricity is used, add JohnDeere PREMIUM DIESEL FUEL CONDITIONER (orequivalent) at the specified concentration.

    Diesel Engine Coolants, Supplemental Additive Information

    Engine coolants are a combination of three chemicalcomponents: ethylene glycol (antifreeze), inhibitingcoolant additives, and quality water.

    Coolant Specifications

    Some products, including John Deere COOL-GARDPrediluted Coolant, are fully formulated coolants thatcontain all three components in their correctconcentrations. Do not add an initial charge ofsupplemental coolant additives to these fullyformulated products.

    Some coolant concentrates, including John DeereCOOL-GARD Coolant Concentrate, contain bothethylene glycol antifreeze and inhibiting coolantadditives. Mix these products and quality water, but donot add an initial charge of supplemental coolantadditives.

    Coolants meeting ASTM D5345 (prediluted coolant) orASTM D4985 (coolant concentrate) require an initialcharge of supplemental coolant additives.

    Replenish Coolant Additives

    The concentration of coolant additives is graduallydepleted during engine operation. Periodicreplenishment of inhibitors is required, even whenJohn Deere COOL-GARD is used. Follow therecommendations in this manual for the use ofsupplemental coolant additives.

    Why Use Supplemental Coolant Additives?

    Operating without proper coolant additives will result inincreased corrosion, cylinder liner erosion and pitting,and other damage to the engine and cooling system. Asimple mixture of ethylene glycol and water will notgive adequate protection.

    Use of supplemental coolant additives reducescorrosion, erosion, and pitting. These chemicalsreduce the number of vapor bubbles in the coolant andhelp form a protective film on cylinder liner surfaces.

    This film acts as a barrier against the harmful effectsof collapsing vapor bubbles.

    Avoid Automotive-Type Coolants

    Never use automotive-type coolants (such as thosemeeting ASTM D3306 or ASTM D4656). Thesecoolants do not contain the correct additives to protectheavy-duty diesel engines. They often contain a highconcentration of silicates and may damage the engineor cooling system.

    Non-Aqueous Propylene Glycol

    Non-aqueous propylene glycol should not be used withJohn Deere diesel engines. This coolant works bestwith coolant temperatures above the acceptableengine operating range. This could decrease enginelife due to lower engine oil viscosity. In addition,electronically controlled engines could experiencepremature power de-rate due to high coolanttemperature.

    Water Quality

    Water quality is important to the performance of thecooling system. Distilled, deionized, or demineralizedwater is recommended for mixing with ethylene glycolbase engine coolant concentrate. All water used in thecooling system should meet the following minimumspecifications for quality:

    Chlorides 40 mg/L or lessSulfates 100 mg/L or lessTotal Dissolved Solids 340 mg/L or lessTotal Hardness 170 mg/L or lesspH Level 5.5 to 9.0

    Freeze Protection

    The relative concentrations of ethylene glycol andwater in the engine coolant determine its freezeprotection limit. Refer to the chart on the followingpage.

    Testing Diesel Engine Coolant

    Maintaining adequate concentrations of glycol andinhibiting additives in the coolant is critical to protect theengine and cooling system against freezing, corrosion,and cylinder liner erosion and pitting.

    Test the coolant solution at intervals of 12 months or lessand whenever excessive coolant is lost through leaks oroverheating.

    Coolant Test Strips

    Coolant test strips are available from your John Deeredealer. These test strips provide a simple, effectivemethod to check the freeze point and additive levels ofyour engine coolant.

    Compare the results to the supplemental coolant additive(SCA) chart to determine the amount of inhibitingadditives in your coolant and whether more John DeereCOOLANT CONDITIONER should be added.

    CoolScan

    For a more thorough evaluation of your coolant, perform aCoolScan analysis. See your John Deere dealer forinformation about CoolScan.

    IMPORTANT: Do not add supplemental coolantadditives when the cooling system isdrained and refilled with John DeereANTIFREEZE/SUMMER COOLANT orJohn Deere COOL-GARD .

    NOTE: If a system is to be filled with coolant that doesnot contain SCAs, the coolant must beprecharged. Determine the total systemcapacity and premix with 3% John DeereCoolant Conditioner.

    Through time and use, the concentration of coolantadditives is gradually depleted during engine operation.Periodic replenishment of inhibitors is required, evenwhen John Deere ANTIFREEZE/SUMMER COOLANTis used. The cooling system must be recharged withadditional supplemental coolant additives available inthe form of liquid coolant conditioner.

    Maintaining the correct coolant conditionerconcentration (SCAs) and freeze point is essential inyour cooling system to protect against rust, liner pittingand corrosion, and freeze-ups due to incorrect coolantdilution.

    John Deere LIQUID COOLANT CONDITIONER isrecommended as a supplemental coolant additivein John Deere engines.

    DO NOT mix one brand of SCA with a differentbrand.

    Test the coolant solution at 600 hours or 12 months ofoperation using either John Deere coolant test strips ora COOLSCAN analysis. If a COOLSCAN analysis isnot available, recharge system per instructions printedon label of John Deere Liquid Coolant Conditioner.

    CAUTION: Explosive release of fluids frompressurized cooling system can cause seriousburns. Shut off engine. Only remove filler capwhen cool enough to touch with bare hands.Slowly loosen cap to first stop to relievepressure before removing cap completely.

    IMPORTANT: Air must be expelled from coolingsystem when system is refilled. SeeCHECKING COOLING SYSTEM inoperators manual.

    The ethylene glycol base (antifreeze) can becomedepleted of SCAs allowing various acids to form that willdamage engine components. In addition, heavy metals,such as lead, copper and zinc, accumulate in the ethyleneglycol base. The heavy metals come from corrosion thatoccurs to some degree with in a cooling system. When acoolant is saturated to the point where it can no longerhold heavy metals and other dissolved solids, they settleout and act as abrasives on engine parts.

    NOTE: Refer to your operators manual for a specificservice interval. See LUBRICATION ANDMAINTENANCE SERVICE INTERVAL CHART inoperators manual.

    Flush cooling system as described in your operatorsmanual. See FLUSHING COOLING SYSTEM inoperators manual.

    IMPORTANT: NEVER overfill the system. Apressurized system needs space forheat expansion without overflowing atthe top of the radiator. Coolant levelshould be at bottom of radiator fillerneck.

    Air must be expelled from coolingsystem when system is refilled. Loosenplug in side of thermostat housing toallow air to escape when filling system.Retighten plug when all the air hasbeen expelled.

    After adding new coolant solution, run engine until itreaches operating temperature. This mixes the coolantsolution uniformly and circulates it through the entiresystem. After running engine, check coolant level andentire cooling system for leaks.
