What This Part Does & Where It Is Fitted
Function
The reservoir stores hydraulic power-steering fluid and supplies the steering hydraulic circuit. It allows fluid volume to be maintained while providing a service point for checking/topping up the correct fluid.
Location
On W639 Vito applications the power-steering reservoir is in the engine compartment. Exact hose routing and mounting arrangement can vary. Compare the listing photographs with the unit on your vehicle before disconnecting anything.

Why Choose a Correct Used Original-Manufacturer Part?
A correctly matched used original-manufacturer component retains the intended moulding geometry, mounting points, hose connections and material specification of the vehicle's original system. Cheap pattern copies can vary in mould quality, connection dimensions and material durability. Buying quality recycled parts can also offer substantial savings versus new dealer pricing — in some categories savings can reach up to 70%, depending on the part and current new price.
Fitting Guide
- Park securely, switch the engine off and allow the engine bay to cool.
- Identify the reservoir and confirm the replacement is physically identical: mounting points, neck/cap, hose ports and orientation.
- Protect surrounding components and extract/contain fluid using suitable workshop equipment.
- Release the reservoir mounting and hose connections using the correct clamps/tools. Plug open hoses to minimise contamination.
- Fit the replacement reservoir with sound seals/clamps as required by the vehicle specification.
- Refill only with the correct approved steering fluid for the VIN.
- Bleed/check the steering hydraulic circuit using the manufacturer procedure, then inspect carefully for leaks and verify steering operation.
Typical tools
Basic socket/spanner set, hose-clamp pliers or suitable pliers, fluid extractor/syringe, drain container, funnel, lint-free cloths, gloves and eye protection. Exact tools depend on the vehicle configuration.
Estimated workshop time: approximately 0.5-1.0 labour hour for straightforward reservoir replacement, excluding diagnosis, seized fittings, flushing, additional leak repair or access complications.
