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.
If topping off is needed, add coolant
which is identical to the initial fill
coolant.
All information subject to change without notice.

Coolant Inhibitor Test Intervals

The coolant inhibitor level should be
checked at the intervals listed in Table
16.
Inhibitor Test Interval
20,000 Miles (32,000 km)
6,000 Miles (9,600 km) or three
months, whichever comes first
6,000 Miles (9,600 km) or three
months, whichever comes first
Supplemental Coolant Additives
for Fully Formulated Coolant —
The concentrations of some inhibitors
will gradually deplete during normal
engine operation. SCAs replenish
the protection for cooling system
components. The coolant must
be maintained with the proper
concentration of SCA. Detroit Diesel
Power Cool maintenance SCAs are
recommended.
The proper application of SCA will
provide:
□ pH control.
□ Restored inhibitor levels to prevent
corrosion.
