TM 10-3930-664-10 1-16. ENGINE LUBRICATION AND COOLING SYSTEMS OIL PAN.  Contains the oil that lubricates moving parts in the engine.  It is attached to the bottom of the engine. OIL PUMP.  Located inside the front housing cover below the water pump.  Draws oil from the oil pan and sends it through the oil cooler, and then through the oil filter.  From the oil filter, oil enters the cylinder block to lubricate the engine and then returns to the oil pan. ENGINE OIL COOLER.  Engine oil flows through the plates of the oil cooler.  Heat from the oil is transferred to the engine coolant which flows from the radiator into the engine block and across the plates of the oil cooler. OIL FILTER.  Removes particles from the oil which could cause damage to the internal parts of the engine. WATER PUMP.  Draws coolant from the radiator and sends it through the oil cooler cavity and cylinder block to cool the engine.  The coolant then returns to the radiator. FAN.  The fan is turned by the engine drive belt.  It creates air flow through the radiator to lower the temperature of the coolant as it passes through the radiator. RADIATOR.  Coolant circulates through the radiator to be cooled after leaving the cylinder block.  The cooling system is full when the coolant level is one inch (2.54 cm) below the filler neck. 1-17. TRANSMISSION LUBRICATION AND COOLING SYSTEMS TRANSMISSION  OIL  FILTER.    Removes  particles  from  the  oil  which  could  damage  the  internal  components  of  the transmission.  A pump mounted on the transmission next to the oil filter produces oil flow through the filter, transmission, and transmission oil cooler. TRANSMISSION  OIL  COOLER.    The  cooler  is  located  behind  the  radiator.    Air  flow  created  by  the  engine  fan  flows through the oil cooler to lower the temperature of the oil as it passes through the cooler. 1-10
