Note:
• Do not mix different brands or types of oil.

3.3.2 Coolant Recommendations
Use only a mixture of 50% long life coolant and 50% clean, softened water to inhibit rust/corrosion and prevent freezing.
A solution of 50% long life coolant provides freezing protection to –37°C (–34°F) and overheating protections to 149°C (300°F).
A coolant solution with less than 50% long life coolant may not provide adequate freezing and overheating protection. Do not
mix long life coolants and conventional coolants. Do not mix different types and/or colors of long life coolants.
