Cooling System
Small problems in the cooling system—like low coolant level or cracked hoses—
can quickly turn into big problems. Anything that’ll interrupt
the flow of coolant can make the engine overheat. If that
happens for even a little while, you’re headed for trouble!
Dear SSG M.U.V.,
Look no more. You can
get that wheel lift using NSN
should spare you a sore back
and wheel and axle damage,
but get a buddy to help you
with the lift.
And order parts through

Dear Half-Mast,
I’m looking for the NSN for the wheel lift that removes wheels from trucks
or semitrailers. It has hydraulics, and I’ve seen it used on M939-series
trucks before in the motor pool. Can you help me?

1.
Make sure the engine’s cool before
testing.
2.
Remove the radiator cap and attach
the pump’s nozzle to the neck of the
radiator.
3.
Work the pump until the gauge
shows the required psi.
4.
Keep an eye on the gauge. If the
pressure’s dropping, there’s a leak
in the cooling system. Listen for
escaping air. And look for coolant
leaks at these places:
- hoses
- hose connections
- water pump
- radiator
- engine freeze plugs
Also look for swollen or bulging
personnel heater hoses. They probably
need to be replaced.
5.
After inspecting, gradually release
the pressure on the pump so that
coolant doesn’t gush out. Remember,
the system’s under pressure.

Wheel Lift
Using wheel lift spares
you a sore back and
wheel and axle damage
ouch!
not having
a wheel lift
is messing
up my back!
just one leaky
hose can drain
the system of
coolant.
prevent this from
happening by testing
the entire cooling
system for leaks.
follow
these
steps…
by the way, if your
vehicle is a 2

/
2-ton
or larger truck,
the st255 radiator
testing kit’s tester
head won’t fit on the
radiator neck.
solve this
problem by
using the
adapter kit
that comes
with nsn 4910-
