POWER COOL 3000 SCA inhibitors
should be mixed at 5% by volume
with water (1 quart per 5 gallons of
water). These additions can be made
by adding liquid SCAs available in a
variety of sizes. Coolant filters are
also available for different cooling
system capacities. These filters release
the proper amount of SCA at initial
fill.
Water Requirements —
Distilled or de-ionized water, which
eliminates the adverse effects of
minerals in tap water, is preferred.
High levels of dissolved chlorides,
sulfates, magnesium, and calcium in
some tap water causes scale deposits,
sludge deposits and/or corrosion.
These deposits have been shown
to result in water pump failures
and poor heat transfer, resulting in
overheating. If tap water is used, the
mineral content in the water must be

Do not add additional SCA to
new, fully formulated antifreeze or
coolant. This can result in dropout
and/or the formation of deposits.

Coolants Not Recommended

The following coolants are not
recommended for use in Detroit Diesel
engines.
All Antifreezes And Coolants
Containing Phosphate — These
coolants are not recommended. Drop
out, overheating and water pump seal
failures can result from the use of
coolant or inhibitor packages based on

phosphate.
