Vacuum Pump

WARNING: This page is about a different car, the 2018 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The vane type vacuum pump is tandem to the oil pump, connected to the vacuum harness via a drilling in the engine block and a vacuum connector. The vacuum produced by the vacuum pump is used to provide a vacuum for the brake booster on the braking system, the active engine mounts.

The vacuum pump extracts air from the brake servo through a vacuum pipe from the servo and a port in the cylinder block. The air extracted from the brake servo flows through the vacuum pipe connector which is equipped with a one way valve to prevent oil ingress into the brake system. The air is vented into the cylinder block via a vacuum exhaust valve.
