Summary of Coolant
Recommendations
HOT COOLANT
To avoid scalding from the
expulsion of hot coolant, never
remove the cooling system
pressure cap while the engine is
at operating temperature. Wear
adequate protective clothing
(face shield, rubber gloves,
apron, and boots). Remove the
cap slowly to relieve pressure.
1. Always maintain the engine
coolant to meet Detroit Diesel
specifications.
2. Only use water that meets the
specifications listed in Table 15.
Distilled, de-mineralized (reverse
osmosis) or de-ionized water is
preferred.
3. The proper dosage of inhibitors
must be included in the coolant
at initial fill for all Detroit Diesel
engines. This dosage is usually
included in the fully formulated
antifreeze used, or it may need to
be added if water alone or if less
than 50% antifreeze is used. The
user is urged to refer to the full
All information subject to change without notice. (Rev. 04/08)

text of this section to determine
the proper dosage. Mixing
of different manufacturers'
technologies (brands) could cause
cooling system problems.
4. Maintain the inhibitor at the
prescribed concentration. Test
the nitrite concentration by using
a titration kit or Detroit Diesel
Power Trac 3-Way Coolant Test
Strips. Add SCA only if the nitrite
concentration is below 900 PPM.
Do not use SCA in OAT coolant,
and do not use Power Trac 3-Way
Coolant Test Strips to test OAT
coolant.
NOTE:
If the nitrite concentration exceeds
3200 PPM, the coolant must be
drained and replaced with new
coolant. A thorough cleaning of the
cooling system may be required.
5. Do not use another manufacturer's
test kit to measure the SCA
concentration of Detroit Diesel
maintenance products.
6. Pre-mix coolant makeup solutions
to the proper concentration before
adding to the cooling system.
7. Do not mix OAT and other
coolants in the same engine.
8. Do not use automotive coolants.
9. Where antifreeze/boil over
protection is required, use only
