Cooling system D5A TA KC (1½-circuit)
The engine cooling water is cooled by, e.g, a box cooler, a grid cooler, or any other external heat exchanger.
When the coolant temperature in the HT-circuit is too high the thermostat valve opens and allows water of a lower
temperature from the LT-circuit to enter the HT-circuit.
The HT-circuit is cooling the cylinder liners, the cylinder heads, and the lubrication oil.. An engine driven HT-pump
circulates the coolant through the engine.
The LT-circuit is cooling the charge air. An engine driven LT-pump circulates the coolant through the CAC.
