Coolant Recommendation; Check The Coolant Level - Honda EX5500 Owner's Manual

3. Check the coolant level.
If there is no coolant in the reserve tank, check the cooling system for leaks
and repair if necessary. Add coolant to the radiator, then check the coolant
level in the reserve tank after the engine reaches operating temperature.
M Never remove the radiator cap when the engine is hot. The coolant
is under pressure and severe scalding could result.
When the engine is at operating temperature, the coolant level should be
between the
MIN
and
MAX
marks on the reserve tank. If the level is near
the MIN mark, add coolant to bring it up to the MAX mark.
Coolant Recommendation
Use high quality ethylene glycol antifreeze that is specifically formulated for
use in aluminum engines. Mix the antifreeze with low-mineral drinking water
or distilled water.
A 50/50 mixture of ethylene glycol antifreeze and water is recommended for
most temperatures and provides good corrosion protection. A higher
concentration of antifreeze decreases cooling efficiency and is recommended
only if additional protection against freezing is needed. A concentration of
less than 40% antifreeze will not provide proper corrosion protection.
CAUTION: The use of unsuitable antifreeze, hard water, or salt water may
cause corrosion damage that will shorten the life of the engine.
