T-72/T-90 and T-80 engine cooling

Image
This article is a simplified approach to explaining how Soviet/Russian engines are cooled.  The T-72 and T-90 series of vehicles are equipped with standard V-84 and V-92 engines. Both engine types feature an enclosed liquid cooling loop with active air-cooling circulation facilitated by a fan.  The T-80 and its GTD series of engines, including the GTD-1000 and the GTD-1250, utilize active air and oil cooling for the turbine. DETAILED LOOK AT THE T-72/T-90 ENGINE COOLING LOOP T-72 engine cooling loop and layout The T-72 uses a closed liquid loop system to cool the engine and two oil lubrication tanks. Coolant heated by the engine is divided into three streams within the engine bay:  The main coolant stream is pumped into the radiators and cooled with atmospheric air, which is pulled into the engine bay using a ventilator. After passing through the radiators, the coolant enters the engine water pump. The second stream flows towards various components, such as the coils ...
