M113-Series FOV: Heater Box Engines Phased Out

BLUF: The M113-series FOV heater box-equipped engine has been replaced by the glow plug engine.

Heads up! The M113-series FOV’s heater box-equipped engine, NSN 2815-01-248-7644, has been phased out and is no longer supported. The replacement is the glow plug engine, NSN 2815-01-412-2715.
If your unit has a vehicle with an unserviceable heater box-equipped engine, you’ll need to replace it with a glow plug engine. Keep in mind you’ll also need the glow plug conversion kit, NSN 2815-01-653-9437. The kit upgrades the vehicle’s electrical system so it’s compatible with the glow plug engine.
Also, don’t dispose of unserviceable heater box-equipped engines. Turn them in to the supply system.
