“Check for wetness
around the radiator
or hoses. Wetness
means a leak. Feel
the hoses and
replace all that
are mushy, cracked
or leaking.”

“While you’re adding
coolant, take a
close look at the
radiator cap. Make
sure it is in top-
notch condition and
is the right cap for
your engine. Check
the pressure rating
on the cap with that
listed in your TM.”
“Check the coolant
level
often.
Before you roll,
when the engine
is still cool, make
sure the coolant
is up to the mark.
If it’s low, add
coolant to bring
the level up.
Never overfill,
though. When the
engine heats up,
the extra coolant
will overflow.”
“Add
coolant
only
when
the engine
is cool.
Adding
coolant to a hot engine
can crack the engine
block or burst a seam
in the radiator.”
“A 60-40 mix
is
best,
but maintain
at least
a
50-50 mix of
antifreeze and
water to raise
the boiling
point of the
coolant so
it won’t boil
away like
plain water.
“Use distilled
water, NSN
in radiators if
it’s available. If
not, use potable
water. Ground
water contains
minerals that
will clog the
radiator.”
Check coolant
level in radiator…
…or surge
tank
“Check the protection
level with tester,
“During operation, keep
an eye on the temperature
gauge. If it goes above
the normal operating
range noted in your TM,
shut down and find
out why.”
Remember, too, that
low
RPMs don’t turn
fans quickly enough
to keep coolant cool.
Gear down to create
more RPMs.
