Only premixed, coolant should be added to the closed‑cooling system. Additives and inhibitors introduced into acceptable
coolant solutions will form a protective film on the internal passages and provide protection against internal cooling system
erosion.
Do not drain the closed‑cooling section for storage. The closed‑cooling section should be kept filled year‑round with an
acceptable antifreeze/coolant solution to avoid rust forming on the internal surfaces. If the engine will be exposed to freezing
temperatures, ensure that the closed‑cooling section is filled with a properly mixed antifreeze/coolant solution to protect the
engine and closed‑cooling system to the lowest temperature to which they will be exposed.
NOTE: It is recommended that a 50/50 solution of coolant (antifreeze) and deionized, purified water be used. A 50/50 solution
will provide freeze protection to –35° C (–31° F). Decreasing the solution to 40/60 will provide freeze protection to –25° C
(–13° F). Even in the warmest climates, never decrease the solution below 40/60. Increasing the solution to 60/40 will provide
freeze protection to –50° C (–58° F).
IMPORTANT: The antifreeze/coolant used in these marine engines must be a low silicate ethylene glycol, containing special
additives, and deionized, purified water. Using other types of engine coolant may cause fouling of the heat exchangers and
overheating of the engine. Do not combine different types of coolants without knowing that they are compatible. Refer to the
coolant manufacturer's instructions.
The acceptable antifreeze/coolants is listed in the following table. Refer to
