The image shows a left-hand drive vehicle with a V8 engine.

Mechanical steering wheel movements are transferred to the wheels via the steering column, steering shaft, steering gear (5) and tie rods. The wheel deflection is limited by a stop in the steering gear.

The oil level is checked using the min/max mark on the servo reservoir (8).

The outer seal is clamped between the steering gear and the floor. The inner seal is secured by plastic mounting elements against the cowl panel from inside the passenger compartment. The seals prevent sound from the engine compartment being transferred into the passenger compartment. They also seal against water, dirt and fire.

The cooling loop (7) reduces the temperature of the oil as the air passes the cooling fins.
