■Recommended Engine 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.
●Shut down 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.
