(8) Engine oil pan
(9) Suction bell
(10) Engine oil cooler When the engine is at normal operating temperature, engine oil pump (6) pulls engine oil from engine oil pan (8) through suction bell (9). The engine oil is pumped to engine oil cooler (10). The engine oil flows through engine oil filter (3) to engine oil manifold (1) in the cylinder block and to supply line (2) for the turbocharger (if equipped). Engine oil from the turbocharger goes back through return line (5) to the engine oil pan.

(10) Engine oil cooler The engine oil filter base has two bypass valves that are designed to open at a differential pressure of 172 21 kPa (25 3 psi). One of the bypass valves is for the engine oil cooler and the other bypass valve is for the engine oil filter. When the engine is cold, the pressure forces the bypass valves open. This provides immediate lubrication to the engine when cold engine oil with high viscosity causes a restriction. The engine oil flows through bypass valves (7) and (4) to engine oil manifold (1) in the cylinder block and to supply line (2) for the turbocharger (if equipped). Engine oil from the turbocharger goes back through return line (5) to engine oil pan (8).After the engine warms up, the differential pressure on the bypass valves decreases
