Until the –10 TMs are updated with cover
use information, here’s what you need to
know:
•
It
can
be removed any time outside temperatures are above freezing.
•
The radiator cover
should
be removed when the outside temperature is above
40
°
F.
•
It
must
be removed before temps reach 70
°
F to prevent equipment damage
from overheating.

rivers, answer this question: Does your FMTV have a cold weather radiator
cover to help keep the engine at normal operating temperature when it’s cold
outside?
If you answered no, you’re like most drivers. In fact, you’ve probably never
even heard of the cover, much less seen it. That’s because there’s no reference to
its use in either -10 TM.
The cover, NSN 2540-01-453-6945, is installed by mechanics when outside
temperatures will be consistently below 40
°
F. Mechanics have to do the work
because installation involves the use of a torque wrench.
rivers, there’s one right way and
any number of wrong ways to se-
cure your vehicle. Doing it right
prevents wiring harness and turn
signal lever damage.
The right way is shown in Re-
vision B versions of TM 9-2320-
365-10 (Para 2-21) and TM 9-
2320-366-10 (Para 2-27). If you
don’t yet have Revision B TMs,
make note of this:
The chain is routed around a
steering wheel spoke and through
the dash-mounted handhold, then
locked.
Family of Medium Tactical Vehicles . . .
If you loop the chain around the
wheel and steering column, you can
cause wiring harness damage.
Plus, using the chain as a handhold
when you get into the cab can dam-
age the turn signal lever.
Install the chain and lock right and
use the handholds provided to get in.
