TM 9-2350-261-10 EQUIPMENT DESCRIPTION — Continued 0002 00 ENGINE COOLANT HEATER KIT. This section describes the engine coolant heater kit found in the M113A2 series carriers. The coolant heater warms the coolant to make starting the engine possible during cold weather operation. The heater is required when temperature is between -25 and -65 F (-32 and -54 C). The heater is not required when temperature is above -25 F (-32 C). A pump circulates coolant through tubing to engine block and battery box heat exchanger to warm the engine block, engine lubricating oil, and the battery electrolyte. Fuel for the coolant heater comes from the engine fuel system. An additional fuel pump is installed to supply fuel under pressure to the heater. The coolant heater is not intended as a quick preheat heater. On the M577A2 and M1068 carriers, a blow torch is installed as part of the engine coolant kit to aid in starting the generator set in cold weather. 0002 00-35 º º º º º º
