Mercedes Sprinter Power Steering Reservoir – Genuine OEM | OM642 3.0L | #0004602883 (2010–2022)

DESCRIPTION:

A cracked or leaking power steering reservoir is one of those problems that starts small and escalates quickly. Low fluid from a leaking reservoir leads to whining, stiff steering, and accelerated wear on the power steering pump. This is the Genuine Mercedes-Benz OEM power steering fluid reservoir for the NCV3 and VS30 Sprinter with the 3.0L OM642 — a direct-fit replacement that seals the hydraulic system and eliminates the leak at its source.

What This Part Does

The power steering reservoir stores hydraulic fluid for the steering system and houses the filter that keeps contaminants out of the pump and rack. It maintains a consistent fluid supply under varying operating temperatures and pressures. Over time the plastic housing can crack, the cap seal can fail, or the internal filter can become clogged — leading to fluid loss, aerated fluid, and reduced steering assist.

Common Symptoms of a Failing Reservoir

• Power steering whining or groaning, especially on cold starts
• Visible fluid leak at or around the reservoir
• Low power steering fluid level with no other obvious source
• Stiff or heavy steering under load

When to Replace It

Replace the reservoir if it's cracked, leaking at the seams, or if the cap no longer seals properly. It's also a smart replacement during any power steering pump or hose service — fresh fluid in a new reservoir ensures the entire hydraulic circuit starts clean. Always use Mercedes-Benz specified power steering fluid (MB 236.3 spec) when refilling.
