Engine Maintenance 9-2
EMI 2000
EMI 2000 is an extended maintenance interval package, which is standard equipment on this unit. The EMI 2000 package
consists of the following key components:
• New EMI 2000-Hour Cyclonic Air Cleaner Assembly and Air Cleaner Element
• New EMI 2000-Hour Fuel Filter (black with gold lettering)
• New EMI 2000-Hour By-Pass Oil Filter (black with gold lettering)
• API Rating CI-4 Mineral Oil
• Five Year or 12,000 Hour ELC (Extended Life Coolant).
The EMI package allows standard maintenance intervals to be extended to 2,000 hours, or 1 year, whichever occurs first.
NOTE: Units equipped with the EMI 2000 package do require regular inspection in accordance with Thermo King's
maintenance recommendations.
NOTE: The new EMI 2000 oil filters and new EMI 2000 air cleaners are NOT interchangeable with the oil filters and air
cleaners previously used in truck unit.
ENGINE LUBRICATION SYSTEM
The engine has a pressure lubrication system. See the appropriate Engine Overhaul Manual for a detailed description of the
engine lubrication system.
Oil pressure is affected by oil temperature, viscosity and engine speed. Subnormal oil pressures usually may be traced to lack
of oil, diluted oil, faulty oil pressure control valve, loose connections in the lubrication system, or worn bearings. Low oil pressure
is not normally caused by a faulty oil pump. The use of improper viscosity oil will also produce low oil pressure shutdowns.
Engine Oil Pressure Switch/Sensor
The engine oil pressure switch/sensor is located on the filter head above the bypass oil filter. Engine oil pressure should rise
immediately on starting. If engine oil pressure drops below 10 ± 2 psig (69 ± 14 kPa), the switch/sensor signals the
microprocessor to stop the engine. See the appropriate Microprocessor Diagnostic Manual for diagnostic information.
Engine Oil Change
The engine oil should be changed according to the “Maintenance Inspection Schedule”. Drain the oil only when the engine is
hot to ensure that all the oil drains out. When changing oil, try to make sure that the truck is not tipped away from the direction
that the oil is supposed to flow from the oil pan. It is important to get as much of the residual oil out as possible because most of
the dirt particles are in the last few quarts of oil to drain out. Refill the pan with oil (see the “Specifications” chapter) and check
the dipstick level. Run the unit, and then recheck the oil level.
NOTE: Fill the crankcase slowly so oil will not run through the crankcase breather into intake manifold and fill up an open
cylinder. Leaving the dipstick out while adding engine oil will vent the crankcase.
CAUTION: The fill port on top of the engine should not be used to add engine oil. To prevent engine lock-up and/or serious
internal damage after TriPac engine oil is added or changed always add oil through the lower port on the timing gear cover.
