■ Coolant
Avoid injury:
●Fluids released under pressure from the
cooling system can cause severe burns.
Pressure build-up in the cooling system can,
when the radiator cap is removed, cause the
coolant to gush out explosively.
●Stop the engine and allow it to cool off.
●Do not remove the radiator cap before the
radiator and the engine are sufficiently cool
such that they can be touched with bare hands.
Carefully loosen the cap to the first stop to
allow the pressure to be completely released.
Only then, remove the cap completely.
[The following coolants are recommended]
• High Quality Permanent Type Antifreeze
(Ethylene Glycol with corrosion and rust inhibitor
chemicals)
Before using the coolant, study the instructions and
data on its container to be sure it is suitable for the
engine.
Use a conditioned coolant, or before use, add a
conditioner to the coolant.
Prepare the coolant by mixing 50% antifreeze with
50% distilled or deionized water, and then pour this
coolant into the radiator. This coolant is intended not
only to cool the engine but also to protect the radiator
against freezing down to a temperature of –34°F (–
37°C).
Follow the instructions on the antifreeze container or
contact your local Cub Cadet Yanmar dealer for
technical assistance. NEVER exceed the maximum
dilution ratio for the coolant. Exceeding the maximum
dilution ratio can jeopardize effectiveness of the
coolant.
