Power Steering Reservoir Cap - the screw cap that closes the power steering fluid reservoir in the hydraulic steering circuit.

It seals the reservoir filler neck, retains the fluid and keeps dirt and moisture out of the system. A hardened, distorted or split cap seal lets fluid weep from the neck and admits air to the low-pressure return side, which shows as foaming fluid, an inconsistent level reading and a noisy pump.

Small enough to be overlooked, but worth renewing whenever the reservoir or the steering hoses are disturbed.

Frequently asked questions

What does the power steering reservoir cap do?
The power steering reservoir cap screws onto the fluid reservoir filler neck, sealing it to retain fluid and keep dirt and moisture out of the hydraulic steering system. Fitted across Discovery 3, Discovery 4, Range Rover L322 and Range Rover Sport L320.
What are the signs the cap needs replacing?
A hardened, distorted or split cap seal typically lets fluid weep from the neck and admits air to the low-pressure return side. That shows as foaming fluid, an inconsistent level reading and a noisy pump on these models.
When is it worth renewing?
Renew the cap whenever the reservoir or steering hoses are disturbed. It is a small part that is easily overlooked, but a poor seal undermines an otherwise sound repair on the Discovery or Range Rover steering system.
