Engine Maintenance Oil Draining: • Refer to the engine manufacturer's Engine Operation and Maintenance Manual supplied with your vehicle for information about draining and refilling engine oil, engine crankcase capacity, engine oil type, and changing oil filters, etc. WARNING! Hot engine oil can be dangerous. You could be seriously burned. Let the engine oil cool down before changing it. • Drain the oil into a container designed for this purpose. • When draining the oil, remove the plug with the proper size wrench and keep as far away as possible. Always keep your forearm parallel to the ground to help prevent hot oil from running down your arm. • The oil filler cap must be secured to avoid oil spill causing a potential fire hazard. Oil Level Check • To check the engine oil level, park the vehicle on level ground and wait 5 minutes after shutting the engine OFF. This allows time for the oil to drain to the oil pan. • Remove the dipstick and wipe it off with a clean, lint-free rag. Preventive Maintenance • Reinsert the dipstick all the way in and pull it out again to check oil level. Correct oil level is between the low (L) and high (H) marks on the dipstick. For further information regarding oil level, see the engine manufacturer's Engine Operation and Maintenance Manual supplied with the vehicle. Fuel System Specification: Use only Diesel Fuel, Grade 2-D, as recommended by engine manufacturers. If you need further information on Grade 2-D fuel specifications, consult the Engine Operation Manual in the glove compartment. WARNING! Diesel fuel in the presence of an ignition source (such as a cigarette) could cause an explosion. You could be killed or seriously injured. A mixture of gasoline or alcohol with diesel fuel increases this risk of explosion. CAUTION: If anyone ever pours gasoline into your fuel tank, drain the entire system. Otherwise, the pump and engine will be damaged. Don't try to dilute the gasoline by adding diesel fuel (see Warning above). – 174 – Y53-6027 Medium Duty (R05/09)
Preventive Maintenance WARNING! Use Ultra Low Sulfur Diesel fuel only. Failure to do so may damage components of the engine and Diesel Particulate Filter (DPF). Please follow these recommendations when you are changing your fuel filters or strainer elements. Your vehicle's engine will run better and last longer if you do. See the engine manufacturer's recommendations for proper water and micron requirements. Installing Fuel Filters When removing filters, cover any electrical equipment and wiring that might get soaked with fuel. Diesel fuel may permanently damage electrical insulation. When installing spin–on (throwaway) filters: 1. Prefill filter with fuel. 2. Moisten gasket with diesel fuel. 3. Hand tighten them only 1/2 to 2/3 turn after gasket contact. Mechanical tightening of these filters may distort or crack the filter head. Engine Maintenance • When replacing a fuel filter element, do not use a substitute. Install only filter elements designed for fuel filtration. First clean and inspect the shell. Then insert the new element and fill the container at least 2/3 full of clean fuel before installing the shell NOTE: To expel air from density-type strainer elements, soak them in clean fuel before installing them. • Throw away old gaskets. Replace them with new ones to ensure a positive seal. • Position the shell and gasket properly. Then tighten the cover nut or bolt just enough to prevent fuel leakage. • After starting the engine, check for leaks around the filter. Filter Draining Check fuel filter/water separator daily. Check with engine OFF. Depending on the fuel storage facility, more frequent draining may be required. 1. Open drain valve (by hand only): turn valve screw counter-clockwise approximately 1 1/2 to 2 turns until draining occurs. Drain filter sump of water until clear fuel is visible.
