4BT-6BT/Cooling-System
The cooling system of the engine is a forced circulation water cooling system, that is, the use of water pumps to increase the pressure of the coolant, forcing the coolant to circulate in the engine. The cooling system is mainly composed of water pump, radiator, cooling fan, compensation water tank, thermostat, water jacket in the engine body and cylinder head and auxiliary devices.
In the cooling system, there are actually two heat dissipation cycles: one is the main cycle to cool the engine, and the other is the interior heating cycle. Both cycles are centered on the engine and use the same coolant.
