ake note, FMTV operators, of these changes to the before-operation checks
of hydraulic coolant and fluid:
The daily coolant level check is changed so you don’t have to open the
radiator overflow tank to see if coolant is somewhere between the lower sight
glass and the upper sight glass.
The surge tank level is acceptable when cool-
ant is visible in the lower sight glass. If coolant
is not visible in the lower sight glass, fill the
surge tank until coolant is visible half-way in
the upper sight glass.
Fill the surge tank with an antifreeze/water
mix using MIL-A-46153 or MIL-A-11755 anti-
freeze as shown in Appendix F of the -10 TMs.
Make note of this change on Page 2-32 of
the -365-10 TM for the 2

-ton model FMTV
and Page 2-56 of the -366-10 TM for the 5-ton
models.
When you make the daily hydraulic fluid
check, remove the reservoir cap to inspect the
fluid level in addition to reading the level gauge.
The reservoir is considered full when the fluid
level is visible at the fill port
and
the fluid level
gauge reads F (full).
This is a double-check of the level gauge, just
to make sure it’s working correctly.

TM 9-2320-366-10 for 5-ton FMTVs. Fill until
oil is visible at the fill port.

the reservoir cap and check the fluid level on
Page 2-53 of the -365-10 and on Page 2-77 of
the -366-10.
pen the doors on most FMTVs and you’ll notice the door seal is pulled loose
right where boots are planted when soldiers climb into the cab.
There’s not much you can do to keep the seal in place—as it is designed. It just
presses into place on the cab.
If all else fails to help keep the seal in place, do a little “designing” on your
own.
Cut the seal from the cab and glue it to the door. That way, you still have a
good seal to keep out dirt and water, and it’s not likely to get booted off.
Use any strong adhesive you have on-hand in the motor pool that can attach
rubber to metal. NSN 8040-00-273-8717 will get you a pint of adhesive specifi-
cally designed to attach rubber to metal. It is an expendable/durable supply item
for FMTVs.
