Turbocharger coolant pump: Notes
Due to the turbocharging and the compact arrangement of the exhaust turbocharger in the V-room, some engines generate a lot of heat. Great importance is attributed to the cooling accordingly. The bearing seats of the exhaust turbocharger are cooled separately by the turbocharger coolant pump. In particular, retained heat from the turbochargers is dissipated after the engine is stopped. The turbocharger coolant pump is integrated in the engine cooling circuit.
