Overview and Specifications
General Information
As engine oil is sucked and delivered from the oil pan by means of the gear-driven oil pump, all of it passes through the oil cooler
and oil filter to be filtered; then, this filtered oil flows through the main oil gallery in the cylinder block to lubricate each engine
bearing and the turbocharger in order to maintain normal engine performance.
