Tactical Vehicles…
what
happened
to you
guys!?
a test kit
could’ve
prevented
that!
why are
you all
frozen?
Water from rain, the wash rack and condensation gets inside the exhaust pipe.
That creates rust that eats away at the pipe. Eventually, the pipe develops leaks and
crumbles away.
A bad exhaust pipe may not
vent the heater’s fumes, including
carbon monoxide. That’s bad news
for anyone inside the vehicle.
Take a look at the exhaust pipe
from the outside the next time the
heater’s running. If you see smoke
or fumes coming from anywhere
other than the end of the exhaust
pipe, there’s a good chance not all
exhaust is being properly vented.
Call in your mechanic.
The best way to prevent this damage is to keep water out of the exhaust pipe
whenever possible. If you’re going to the wash rack, cover the pipe with a plastic bag
before you start washing. If the vehicle’s going to sit in the motor pool for a while,
seal the exhaust pipe with a plastic cap or cover it with a tarp to keep out rain. Just
remember to remove them before operation.
Taking a few precautions to keep out moisture will let your AVLB—and you—
breathe easier.

extra care
with the avlb’s personnel heater

easy during the next cold snap.
Smoke or
fumes coming
from here?
Call your

if only they’d
cover my personnel

I can feel
the
rust
starting now!
i
s your vehicle’s cooling system ready to perform in all types of weather? If you’re
not sure, test it. This should happen at least during scheduled maintenance and
climatic change services.
The combination antifreeze and
battery tester, NSN 6630-00-105-
1418,
tests
for
freeze
protection
down to -50°F. Use this only for
50/50 blend antifreeze.
Antifreeze test kit, NSN 6630-01-
011-5039, tests for freeze protection
down to -60°F. The test strips in this
kit can be used for both the 50/50
and 60/40 antifreeze blends.
Use commercial test strips to test the nitrite (corrosion protection) level of
antifreeze. The ideal nitrite concentration for 50/50 antifreeze/water solution is
between 1,200 and 1,400 ppm.
