TM 5-3895-383-24
Cooling System Coolant Additive (DEAC) - Add
SMCS Code: 1352-544
At operating temperature, the engine coolant is hot and
under pressure.
Steam can cause personal injury.
Check the coolant level only after the engine has been
stopped and the fill cap is cool enough to touch with your
bare hand.
Remove the fill cap slowly to relieve pressure.
Cooling system conditioner contains alkali. Avoid contact
with the skin and eyes to prevent personal injury.
See Operation and Maintenance Manual, "Cooling System
Specification" for all cooling system requirements.
NOTICE
Excessive additive (greater than the recommended 6%
initial fill) together with concentrations of antifreeze
greater than 60% cause deposits to form and can result in
radiator tube blockage and overheating.
Use 8T-5296 Test Kit in order to check the concentration.
