Coolant
Servicing Your Honda
Increasing the concentration of antifreeze
is not recommended because it decreases
cooling system perf ormance. Higher
concentrations of antifreeze (up to 60%)
should only be used to provide additional
protection against freezing. Check the
cooling system f requently during f reezing
weather. Decreasing the concentration of antifreeze
to less than 40% will not provide proper
corrosion protection.
