TM 9-2350-358-BD SECTION II. COOLING SYSTEM 6-4. GENERAL The howitzer has a liquid cooling system consisting of a radiator, two fans, tubes, hoses, fittings, clamps, a surge tank and an engine-driven water pump. To maintain normal operating temperature of the engine, the liquid flow through the cooling system is controlled by an inlet and a bypass thermostat. Battle damage to the cooling system would degrade, and if not repaired, eliminate the mission capability of the howitzer. The most expedient method to correct cooling system problems is by replacing components, many of which are interchangeable with components of other combat vehicles. 6-3
