330 422 371 Power Steering Fluid Reservoir for VOLKSWAGEN

The 330 422 371 power steering fluid reservoir is an OE-reference oil container used on selected Volkswagen Passat and Santana hydraulic steering systems. Its elongated translucent body lets technicians monitor fluid condition while maintaining a gravity-fed reserve above the steering pump.

This reservoir belongs to a long-running VAG application family that spans different markets and production periods. Buyers should treat the OE number, installed orientation and hose layout as the decisive identification evidence instead of relying on the vehicle name alone.

Tall Reservoir Design and Fluid Supply

The vertical cylindrical layout stores steering oil in a narrow engine-bay footprint. A sound lower outlet helps maintain an uninterrupted pump feed, while the upper return area gives entrained air an opportunity to separate before the fluid circulates through the rack again.

Passat and Santana Application Verification

Public VAG catalogues associate 330 422 371 with Passat, Passat Syncro, Santana and market-specific Santana 2000 or 3000 applications. Final approval should use the VIN, steering-system configuration, original moulded number and a comparison of the mounting position.

What to Compare on the Removed Reservoir

Measure the body height and diameter, then check cap construction, lower outlet angle, side support and hose clearance. A shorter bottle or a differently positioned connection can disturb hose routing even when the capacity appears similar.

Service Cleanliness and Acceptance Checks

Power steering pumps are sensitive to dirt and air. Incoming inspection should confirm a clean interior, an even cap seat, an undamaged translucent shell and a smooth outlet without moulding flash. Keep the connection covered until installation.

Classic VAG Procurement Planning

SKU VM01016-001 supports restoration workshops and wholesalers carrying long-tail Volkswagen steering parts. Quote requests should state OE 330 422 371, intended vehicle market, sample quantity, annual demand and any neutral-label or private-label packaging needs.

Frequently Asked Questions

What vehicles are commonly linked to 330 422 371?

Catalogue references include Volkswagen Passat, Passat Syncro and Santana applications, with additional market-specific variants. Confirm the exact vehicle by VIN.

Is 330 422 371 a coolant expansion tank?

No. This product is identified as an oil container for the hydraulic power steering circuit, not an engine-coolant reservoir.

Why is the tall body shape important?

The shape determines bracket clearance, fluid level and hose alignment. A reservoir with the wrong height or outlet position may not install correctly.

What should be inspected when steering fluid foams?

Check fluid level, suction-hose sealing, return flow, reservoir cleanliness and pump condition because air can enter at several points in the circuit.

How can a distributor request a quotation?

Send 330 422 371, SKU VM01016-001, quantity, destination and original-part photographs for application and packing review.

Request an 330 422 371 Reservoir Quote

Send OE 330 422 371, SKU VM01016-001, required quantity, destination and removed-part evidence to AutoParts for a fitment review and wholesale proposal.

Fitment notice: OE and vehicle references support identification, but final compatibility requires VIN-, engine- and chassis-specific catalogue checks plus direct comparison with the removed reservoir.

Inspection focus: Compare the long cylindrical body, cap, lower outlet, mounting position and hose route.
