IMPORTANT: Use only Mercury MerCruiser specified coolant. Use of other coolant
may cause fouling of the heat exchangers, and overheating of the engine.
These specified, premixed formulas require no mixing with water or other additives. The
low silicate ethylene glycol, special additives, and purified water formulas prevent
silicate gelling which can restrict engine cooling passages. They provide protection down
to –38 degrees C (–33 degrees F).
