Engine Maintenance
EMI 3000
EMI 3000 is an extended maintenance interval
package. It was phased in as standard equipment
on this unit in the first quarter of 2001. The EMI
3000 package consists of the following key
components:
• New EMI 3000-Hour Cyclonic Air Cleaner
Assembly and Air Cleaner Element
• New EMI 3000-Hour Fuel Filter (black with
gold lettering)
• New EMI 3000-Hour Dual Element Oil Filter
(black with gold lettering)
• API Rating CI-4 Mineral Oil (ACEA Rating
E3 for Europe)
• Five Year or 12,000 Hour ELC (Extended Life
Coolant).
The EMI package allows standard maintenance
intervals to be extended to 3,000 hours, or 2 years,
whichever occurs first.
NOTE: Units equipped with the EMI 3000
package do require regular inspection in
accordance with Thermo King’s maintenance
recommendations.
NOTE: The new EMI 3000 oil filters and new
EMI 3000 air cleaners are NOT interchangeable
with the oil filters and air cleaners previously
used in trailer units.
Engine Lubrication System
The TK 486 engine has a pressure lubrication
system. Refer to the TK 482 and TK 486 Engine
Overhaul Manual TK 50136 for a detailed
description of the engine lubrication system.
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, keep unit and
trailer level so all the oil can flow from the oil
pan. It is important to get as much of the oil out as
possible because most of the dirt particles are
contained in the last few quarts of oil that drain
out of the pan. Refill the pan with 13 quarts
(12.3 liters) and check the dipstick level. Run the
unit, and then recheck the oil level. The engine oil
level should be at the FULL mark with the
dipstick turned (threaded) into the oil pan. Never
overfill. See Specifications Chapter for correct
type of oil.
Oil Filter Change
The oil filter should be changed along with the
engine oil. Use a genuine Thermo King extended
maintenance oil filter.
1. Remove the filter.
2. Apply oil to the rubber ring of the new filter
and install the filter.
3. Tighten the filter until the rubber ring makes
contact, then tighten 1/2 turn more.
4. Start the unit and check for leaks.
Low Oil Pressure
Oil pressure is affected by oil temperature, oil
viscosity, and engine speed. Low oil pressure can
usually be traced to the lack of oil, a faulty oil
pressure regulating valve, or worn bearings. Low
oil pressure is not normally caused by a faulty oil
pump. Use the “Low Oil Pressure Flow Chart” on
the following page to help diagnose low oil
pressure.
