Looking for Leaks?
D
rivers, nothing±s more irritating than a coolant leak on your MLRS that you
can±t find² Unfortunately, that±s what happens when the leak is coming from
coolant hose, NSN 4720-01-109-2052²
Leaks from that hose drip straight down on the engine manifold² The intense
heat from the manifold immediately evaporates the coolant² With the coolant
gone, you can±t find any trace of a leak²
To make matters worse, the hose may
only leak when engine heat makes it
expand² Once the engine cools down,
the hose contracts and the leak often
disappears²
Stop those leaks from happening²
Eyeball the hose quarterly for cracks
and feel for softness² If you find either, get your mechanic to replace the hose²
Clean inside and outside
of ballistic windows
Check hose quarterly for cracks or softness
ay you don±t do windows? When it comes to the cab windshields on your
MLRS, it±s better not to do anything than to clean ±em the wrong way²
Cleaning the windshields with high-pressure water or steam is definitely the
wrong way² The heat and high pressure loosen the adhesive that binds the glass
layers together² The glass turns hazy or opaque, making it very hard for crew-
men to see² If it gets bad enough, your vehicle is NMC²
Here±s the right way to clean cab windshields:
1±
Flush the outside window surface
with low-pressure water² Wipe the in-
side surface with a wet sponge or soft,
wet cloth²
MLRS ± ± ±
Keep clothing buckles, buttons, and zippers away from the window surfaces²
3±
Flush the outside surface again with clean water² Wipe the inner surface with
a sponge or cloth and clean water until the detergent is removed²
4±
Dry each surface by lightly wiping with a clean, dry cloth using straight
strokes from the top to the bottom² That prevents streaking²
2±
Wipe both surfaces lightly with a
sponge or soft cloth saturated with
a solution of general purpose deter-
gent, NSN 7930-00-880-4454, and wa-
ter² Use
1
/
4
ounce of detergent per
gallon of water²
Use sponge and soapy water only
oww!
how do you
expect
either
of
us to
see
with
treatment like
that!
