On the V6 3.0L Petrol S/C engine, the brake vacuum pump is a mechanically driven vane pump installed on the front of the engine sump body. The auxiliary chain drives the pump. Two bolts attach the brake vacuum pump to the sump body. A seal is installed in a groove on the mating face of the vacuum pump.
The brake vacuum pump drive gear locates on the end of the rotor and engages with slots in the front of the auxiliary camshaft. An oil tube in the center of the rotor supplies engine oil from the auxiliary camshaft to lubricate the brake vacuum pump. Exhaust air from the brake vacuum pump is expelled into the engine sump through the sump body.
The brake vacuum pump drive gear locates on the end of the camshaft with slots.
