echanics, if you’ve been getting complaints of a hot-running engine
in an M109-series howitzer or M992-series ammo carrier, check the radiator
shroud seals.
The seals form an air barrier between the radiator and fan tower. That barrier
increases air flow through the radiator to keep the engine cool. If seals are
missing, torn, squashed or mangled,
air escapes around the sides of the
radiator. Engine temperature goes up.
Eyeball the shroud seals next time
the pack’s out. If the seals are miss-
ing or torn, order new ones. Check
the -24P manual for the correct seals
on your vehicle.
