ELC (Extended Life Coolant)
ELC has been phased into these units as of the
first quarter of 2001. The maintenance interval for
ELC is 5 years or 12,000 hours. A nameplate on
the coolant expansion tank identifies units with
ELC.
NOTE: The new engine coolant, Texaco
Extended Life Coolant, is Red in color instead of
the current Green or Blue-Green colored
coolants.

Tank
The following are the Extended Life Coolants
currently approved by Thermo King for use in
ELC units for five years or 12,000 hours:
•
Texaco ELC #16445 (nitrite free) 100%
concentrate.
•
Texaco ELC #16447 premixed 50/50%
concentrate.
•
Havoline Dex-Cool #7994 (nitrite free) 100%
concentrate, or #7997 (with nitrites) 100%
concentrate.
•
Havoline Dex-Cool #7995 (nitrite free)
premixed 50/50% concentrate.
•
Shell Dexcool #94040.
•
Shell Rotella #94041.
•
Havoline XLC #30379 (Europe) 100%
concentrate.
•
Havoline XLC #33013 (Europe) premixed
50/50% concentrate.
•
Saturn/General Motors Dex-Cool.
•
Caterpillar ELC.
•
Detroit Diesel POWERCOOL Plus.
NOTE: The use of 50/50% pre-mixed Extended
Life Coolant (ELC) is recommended to assure
that de-ionized water is being used. If 100% 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.
ELC cannot be used in all older units. The water
pump seal bellows and o-rings used on older units
are not compatible with ELC.
To upgrade new production engines for ELC use,
all water pump seal bellows were changed from
NBR to HNBR elastomer, and the o-rings
upgraded from NBR to EPDM elastomer. These
changes were made as of TK 3.74 engine serial
number A02105.
Units with engine serial numbers A02105 and
after can be changed over to ELC coolant. The
cooling system must be flushed until all traces of
green or blue-green coolant dye are gone, and the
discharge fluid (water) is clear. The system can
then be filled with extended life coolant (ELC).
Units with engine serial numbers before A02105
must have the water pump replaced to change
over to ELC coolant. See Service Bulletin
T&T 275 for information about retrofitting the
new water pump.
CAUTION: NEVER add Red Extended
Life Coolants to cooling systems using
Green or Blue-Green coolants. NEVER
add Green or Blue-Green coolants to
cooling systems using Red Extended Life
Coolants.
