Coolant

Your ATV's liquid cooling system dissipates engine heat through the
coolant jacket that surrounds the cylinder and cylinder head.
Maintaining the coolant will allow the cooling system to work properly
and prevent freezing, overheating, and corrosion.
Coolant Recommendation
Use Pro Honda HP coolant or an equivalent high quality ethylene glycol
antifreeze containing corrosion protection inhibitors specifically
recommended for use in aluminum engines. Check the antifreeze
container label.
Use only distilled water as a part of the coolant solution. Water that is
high in mineral content or salt may be harmful to the aluminum engine.
Using coolant with silicate inhibitors may cause premature wear of
water pump seals or blockage of radiator passages. Using tap water
may cause engine damage.
The factory provides a 50/50 solution of antifreeze and water in this
ATV. This coolant solution is recommended for most operating
temperatures and provides good corrosion protection.
Decreasing the concentration of antifreeze to less than 40% will not
provide proper corrosion protection.
