Where is the oil pump located in the Passat B5?

[SanMia]

The oil pump in the Passat B5 is located inside the engine. You need to remove the right side cover of the engine, and it is positioned at the lower front part of the engine. Structure of the oil pump: It features a simple structure, compact size, lightweight, and high oil delivery capacity. The cycloidal rotor pump adopts a meshing structure with inner and outer rotors, featuring fewer teeth and a compact structural design. It forms a sealed chamber without the need for additional isolating components, resulting in a reduced number of parts. Operational characteristics: It operates smoothly with low noise. The cycloidal rotor pump has only a one-tooth difference between the inner and outer rotors. During relative motion, the sliding speed between tooth surfaces is low, and the meshing point continuously moves along the tooth profiles of the inner and outer rotors, resulting in minimal wear between the two rotor surfaces. Due to the large enveloping angle of the oil suction and discharge chambers, close to 145 degrees, both oil suction and discharge processes are sufficiently timed, ensuring smooth oil flow and stable operation. Additionally, the noise level is significantly lower than that of gear pumps.
