1. Lubrication system
Engine oil is supplied from the oil inlet pipe to lubricate and cool the full-floating bearings inside the center housing. After that, the oil passes through the oil outlet pipe and returns to the oil pan.
2. Cooling system
The turbocharger is cooled by the engine coolant. The engine coolant is introduced into the coolant channel inside the center housing via the coolant inlet pipe. The engine coolant returns to the water pump via the coolant outlet pipe after cooling the turbocharger system.
