10. Do not use the following in
Detroit Diesel engine cooling
systems:
□

□
High silicate, automotive-type
antifreeze
□

Coolant life of Glycol Coolant —
A
properly maintained
cooling
system,
fi
lled with phosphate-free
coolant consisting of a 50/50 mix of
antifreeze and water per TMC RP-329
“Type A” EG or TMC RP-330
“Type A” PG speci
fi
cations can be
operated to the limits recommended.
The proper maintenance involves
periodic evaluation using Power Trac
3-Way Coolant Test Strips and the
addition of SCA as needed, indicated
by the strip test. To verify coolant
acceptability, submit a sample for
coolant analysis every 300,000 miles
(480,000 km), three (3) years, or
5,000 operating hours, whichever
comes
fi
rst. Submit the sample in
a DDC Power Trac Coolant Test
Bottle. Required part numbers are
in refer to section
ENGINE PRODUCTS.
Coolant Life of OAT Coolant —
A
properly maintained OAT coolant may
be operated 600,000 miles (960,000
km), four (4) years, or until overhaul,
whichever comes
fi
rst. At this time the
system
must
be completely drained,
thoroughly cleaned, and re
fi
lled. OAT
Coolants require the addition of an
extender at 300,000 miles (480,000
km), two (2) years, or 5,000 hours,
whichever comes
fi
rst. Use 1 pint
of extender for every 20 gallons of
coolant.
Coolant Life of Other Coolants —
Other properly maintained coolants
may be operated up to 250,000 miles
(480,000 km), two (2) years, or 4,000
operating hours, whichever comes
fi
rst. At this time the system
must
be completely drained, thoroughly
cleaned, and re
fi
lled.
