our Stryker’s going to get a little hot under the collar if you don’t keep an eye
on coolant levels, drivers.
To help your Stryker keep its cool, check those coolant levels after every
operation. Just make sure you let the engine cool before removing the cap to
make the check.
Otherwise, hot coolant can spray from the opening, causing severe burns.
It’s also a good idea to wear protective gloves and chemical goggles to protect
your eyes and skin just in case.
Open the front service
and engine cover hatches
and eyeball the sight glass
on the surge tank. The sight
glass should be completely
full. If it’s not, remove the
pressure cap on top of the
surge tank and add coolant
until the sight glass is full.
Next, check the coolant
overflow reservoir. If the
coolant isn’t above the FULL
COLD mark, remove the cap
and add coolant.
The
right
amount
of
coolant in the surge tank
and overflow reservoir is
just what your Stryker needs
when the heat is on.

ust because you
can
use the PANEL LIGHTS knob to completely dim the lights
on the commander’s panel of your M1A1 tank doesn’t mean you
should.
In fact, you
deFnitely shouldn’t.
Dimming those lights completely is
a real safety hazard, especially when it
comes to the warning lights.
One crew learned that lesson the hard
way when the NBC Flter on their tank
caught Fre after the air cycle turbine
failed. The crew reported that the NBC

light
didn’t provide any warning. It turned out
that the warning light was working but
had been completely dimmed.
So follow the information on Page 2-301 of TM 9-2350-264-10-1 (Mar 02 w/Ch
4, Dec 07). It tells you how to test the panel lights and adjust the PANEL LIGHTS
knob so the lights are dimmed but still readable. Never dim them completely.
