NOTE:
Power Cool 3000 liquid SCA is more
compatible with hard water than
Power Cool 2000 SCA.
Power Cool
Coolant Filter
Elements —
Power Cool coolant
filter elements (spin-on canisters) are
available in various sizes suitable for
cooling systems of varying capacities.
Selection of the proper element size
is vital when pre-charging non-fully
formulated coolant (i.e., water) at
initial fill and at maintenance intervals.
A fully formulated antifreeze must
not have SCA added at initial fill.
Do not use SCA-containing filters
with OAT antifreeze or coolant.
The need for maintenance elements
is determined by the results of the
nitrite concentration test performed
at each cooling system interval.
Do
not automatically install maintenance
elements at maintenance intervals,
unless the nitrite concentration falls
below 900 parts per million.

Summary of Coolant
Recommendations
To avoid injury from the expulsion
of hot coolant, never remove the
cooling system pressure cap
while the engine is at operating
temperature. Remove the cap
slowly to relieve pressure. Wear
adequate protective clothing
(face shield or safety goggles,
rubber gloves, apron, and boots).
1. Always maintain the engine
coolant to meet Detroit Diesel
specifications.
2. Only use water that meets the
specifications listed in Table 24.
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
text of this section to determine
the proper dosage.
