TM 9-2350-311-20-1 CHAPTER 14 ENGINE AND BATTERY WINTERIZATION KIT GENERAL This chapter provides instructions for removal, disassembly, assembly, and installation of specific components of the winterization kit. Since the kit encompasses several components, each with an individual set of procedures, the chapter has been divided into an overall diagram and nine major components of the winterization kit. The winterization kit provides a standby heating system to prevent freezing of the engine coolant and battery electrolyte during shutdown periods in extreme cold or arctic temperatures. Coolant is circulated through the heater, engine, and battery heater by an electrically driven coolant pump furnished with the kit.
