9. Where antifreeze/boil over
protection is required, use only
antifreeze that meets TMC
RP-329 "Type A" (EG) or
TMC RP-330 "Type A" (PG)
specifications. Always maintain
coolant at the proper level.
10. Coolant life of Glycol Coolant:
A properly maintained cooling
system, filled 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)
specifications 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 first. Submit the sample in
a DDC Power Trac Coolant Test
Bottle. Required part numbers
are listed in Table 47
11. 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 first. At this time the

drained, thoroughly cleaned, and
refilled. OAT Coolants require
the addition of an extender at
300,000 miles (480,000 km),
two (2) years, or 5,000 hours,
whichever comes first. Use 1 pint
of extender for every 20 gallons
of coolant.
12. 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 first.
At this time the system must be
completely drained, thoroughly
cleaned, and refilled.

Detroit Diesel engine cooling
systems:
Soluble oil
High silicate,
automotive-type antifreeze
Chromate SCAs
Methoxy propanol-base
