MAINTENANCE
The coolant mixture should
not exceed 50% anti-freeze by
volume.
Freezing temperatures can quick-
ly and severely damage the engine
if the cooling system is unprotected.
Use antifreeze when temperatures
fall below 32
o
F (0
o
C).
1. Only use permanent anti-freeze in
this engine.
2. Completely drain and flush the
cooling system with clean water
before adding anti-freeze.
3. Mix the proper amounts of an-
ti-freeze and pure water in accor-
dance with SAE J1034 and SAE
J814C based on the expected am-
bient temperature.
4. Mix the anti-freeze and water be-
fore pouring it in the cooling sys-
tem.
This data is the industry stan-
dard for a typical ethylene glycol
based antifreeze. These volumes
of anti-freeze, when mixed with
pure water, will reduce the freez-
ing point of the coolant mixture
as shown.
When adding coolant during dai-
ly service, use only water or an-
ti-freeze mixed with water to en-
sure that the mix ratio stays at or
below 50% anti-freeze.
Keep unused anti-freeze in a
clean, tightly sealed container.
Do not use radiator cleaning
agents when anti-freeze has
been added to the cooling water.
(Anti-freeze contains an anti-cor-
rosive agent, which will react with
the radiator cleaning agent form-
ing sludge which will affect the
engine parts.)

*At 760 mmHg pressure (atmospher-
ic), a higher boiling point is obtained
by using a radiator pressure cap
which permits the development of
pressure within the cooling system.
