MBE 900 COOLANT

Coolant is a mixture of water and antifreeze. Under normal conditions, it is a mixture of 50 percent water and 50 percent antifreeze, but under extreme cold weather conditions, as much as 60 percent antifreeze can be added. Mixtures above 60 percent may reduce cooling effectiveness and reduce heat transfer capability of the coolant. For reasons of anticorrosion protection and to raise the boiling point, the coolant must remain in the cooling system all year round. ‪

Regardless of mileage, replace the coolant every two years since the degree of corrosion protection gradually drops with time. ‪

Fully Formulated Antifreeze

Antifreeze approved for use in the MBE 900 engine is a mixture of ethylene glycol and corrosion inhibitors. Antifreeze containing ethylene glycol and corrosion inhibitors is known as fully-formulated antifreeze. ‪

Note: Do not use propylene glycol.

Fully-formulated antifreeze has the following properties: ‪

  • It protects the radiator and engine from freezing.
  • It provides protection against corrosion and cavitation for all components in the cooling system.
  • It raises the boiling point of the coolant. This slows the rate of evaporation, avoiding coolant loss at high temperatures.
