3. Retards corrosion (acid) that can attack accumulator tanks, water tubes, radiators, and core plugs.
4. Provides lubrication for the water pump seal.
Extended Life Coolant (ELC)
ELC is used in this unit. A nameplate near the coolant expansion tank identifies units with ELC.

NNoottee:: The new engine coolant, Chevron Extended Life Coolant, is RED in color instead of the current GREEN or BLUE-
GREEN colored coolants.

The following are the Extended Life Coolants currently approved by Thermo King for use in ELC units for five years or
12,000 hours:
• Chevron Dex-Cool
• Texaco ELC (nitrite free)
• Havoline Dex-Cool (with nitrates)
• Havoline Dex-Cool (nitrite free)
• Shell Dexcool
• Shell Rotella
• Havoline XLC (Europe)
• Saturn/General Motors Dex-Cool
• Caterpillar ELC
• Detroit Diesel POWERCOOL Plus
NNoottee:: The use of 50/50 percent pre-mixed Extended Life Coolant (ELC) is recommended to assure that de-ionized water
is being used. If 100 percent full strength concentrate is used, de-ionized or distilled water is recommended over
tap water to insure the integrity of the cooling system is maintained.
Antifreeze Maintenance Procedure
As with all equipment containing antifreeze, periodic inspection on a regular basis is required to verify the condition of
the antifreeze. Inhibitors become worn out and must be replaced by changing the antifreeze. Change ELC (red) engine
coolant every five years or 12,000 hours (whichever occurs first).
Do not mix green or blue-green engine coolant with ELC (red) engine coolant. See “Extended Life Coolant (ELC)” for
more information about ELC.
The factory recommends the use of a 50/50 antifreeze mixture in all units even if they are not exposed to freezing
