Water Only + Sca Or Water Only + Oat Inhibitor - Detroit Diesel MBE 900 Operator's Manual

OAT coolants should not be mixed
with conventional coolants. If they
are mixed, no damage will result, but
the long-life advantages of the OAT
coolant will be lost. In this event, the
coolant should be maintained as a fully
formulated Inhibited Ethylene Glycol
(IEG) coolant, not as an Organic Acid
Technology (OAT) coolant.
Detroit Diesel markets a OAT-
inhibited ethylene glycol coolant,
DDC Power Cool Plus, which
contains all the required additives.
If a non-DDC OAT antifreeze is
used, it must conform to TMC 338
specification. Do not add extender to
new OAT antifreeze or coolant.
Water Only + SCA or Water
Only + OAT Inhibitor — In
warm climates a coolant based
on water with corrosion inhibitors
is approved for use. Water-only
systems need to be treated with the
proper dosage of corrosion inhibitors.
Detroit Diesel-approved SCAs or
OAT corrosion inhibitors must be
added to the water to provide required
corrosion and cavitation erosion
protection. OAT inhibitors such as
Power Cool Plus 6000 are available
for water-only systems. Inhibitor
should be mixed at 7.5% – 10% by
volume with water. For a list of Power
Cool products,refer to section POWER

Cool 3000) can also be used to
protect the engine. Power Cool 3000
concentration limits are listed in Table
14.
NOTE:
Do not use Power Trac 3–Way Test
Strips to test OAT coolant.
POWER COOL® 3000 SCA inhibitors
should be mixed at 5% by volume
with water. This is 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.
