The oil lubrication system is a full-flow filtration, pressure feed type. The oil pump body (7) is mounted to the engine block. The pump inner rotor (3) is driven by the crankshaft (1). A windage tray, increases engine power by minimizing oil windage at high engine RPM. For increased engine oil cooling, an engine oil-to-engine coolant oil cooler is used.
All engines are equipped with a high quality full-flow, disposable type oil filter (2). When replacing oil filter, use a Mopar® filter or equivalent.
