Hose For Transporter T5 2005 Power steering fluid tank reservoir 7h0422371a

#85

Genuine used Volkswagen Transporter T5 Power Steering Fluid Reservoir Hose / PAS Hydraulic Hose, removed from a 2005 Volkswagen Transporter T5 and used in conjunction with the power steering fluid reservoir 7H0422371A.

This hose forms part of the hydraulic power-assisted steering system, carrying power steering fluid between the reservoir and the associated PAS hydraulic components.

Part Details

Part Type: Power Steering Fluid Reservoir Hose / PAS Hose

Application: Power Steering Reservoir Connection

Reservoir Reference: 7H0422371A

VW Reservoir OE Number: 7H0 422 371 A

System: Hydraulic Power Steering / PAS

Donor Vehicle Reference: Volkswagen Transporter T5 2005

Manufacturer: Volkswagen / Genuine OE

Condition: Used Genuine Part

Important: 7H0422371A is the OE reference for the associated power steering fluid reservoir. The hose itself may have a separate VW part number.

Compatibility

Suitable for selected:

* Volkswagen Transporter T5 – 2003–2009

* Volkswagen Caravelle T5

* Volkswagen Multivan T5

* Transporter Panel Van

* Transporter Kombi

* Transporter Shuttle

* Transporter Flatbed / Chassis Cab

* Selected camper and conversion models

The 7H0422371A reservoir is documented for the T5 hydraulic power-steering system and is found on multiple T5 engine configurations.

Exact hose compatibility can vary depending on:

* Engine

* Power steering pump

* Hydraulic pipe arrangement

* Production date

* Hose routing

* Connection diameter

For this reason, buyers should compare the supplied hose directly with their original.

Technical Information

The Transporter T5 uses a hydraulic power-assisted steering system.

Power steering fluid circulates through components including:

* PAS fluid reservoir

* Reservoir hoses

* Power steering pump

* Hydraulic pressure pipes

* Steering rack

* Return pipework

* Power steering oil cooler where fitted

The reservoir hose provides part of the hydraulic connection required for fluid to circulate correctly through this system.

Power Steering Reservoir Information

The associated reservoir carries VW reference:

7H0422371A

7H0 422 371 A

This is the hydraulic power steering fluid reservoir used on selected Volkswagen Transporter T5, Caravelle and Multivan applications.

The reservoir and connecting hoses are separate components, so 7H0422371A should be treated as the reservoir reference rather than automatically as the hose’s individual OE number.

Common Reasons for Replacement

A power steering reservoir hose may require replacement because of:

* Hydraulic fluid leakage

* Cracked rubber hose

* Hose deterioration with age

* Split hose

* Damaged connection

* Loose or damaged hose end

* Oil contamination

* Hose becoming hard or brittle

* Previous engine-bay damage

* Damage during power steering repairs

Common Symptoms / Problems

A damaged or leaking PAS hose can potentially cause:

* Power steering fluid loss

* Wet/oily hose surface

* Fluid around the reservoir

* Low fluid level

* Power steering pump whining

* Heavy steering

* Intermittent steering assistance

* Air entering the hydraulic system

* Foaming inside the reservoir

If the fluid level repeatedly drops, the complete hydraulic system should be inspected for leaks.

Important Diagnostic Information

Before replacing the hose, inspect:

* Power steering reservoir

* Reservoir outlet/inlet connections

* Hose condition

* Hose clamps

* Adjacent hydraulic pipes

* Power steering pump

* Steering rack

* Return pipework

* PAS cooler where fitted

Pay particular attention to the hose ends, as leaks can develop where the rubber hose meets a connection or clamp.

Power Steering Fluid Information

Use only the correct Volkswagen-approved hydraulic power steering fluid specification for the vehicle.

Do not automatically substitute conventional ATF.

Using incorrect or contaminated hydraulic fluid can affect the power steering pump, seals and steering rack.

Installation

When installing the replacement hose:

* Keep all hydraulic connections clean

* Prevent dirt entering the PAS system

* Inspect the reservoir connection

* Inspect hose clamps

* Replace damaged clamps where necessary

* Route the hose in its original position

* Avoid twisting or kinking the hose

* Keep it away from moving or excessively hot components

* Refill with the correct hydraulic fluid

* Bleed the PAS system correctly

* Check fluid level after bleeding

* Inspect all connections carefully for leaks

Do not allow the power steering pump to run dry, as insufficient lubrication can damage the pump.

Programming / Coding

No programming or coding required.

This is a mechanical/hydraulic component.

Important Compatibility Note

The hose should not be purchased using 7H0422371A alone, because that number identifies the associated reservoir.

Before ordering, please compare:

Associated Reservoir: 7H0422371A / 7H0 422 371 A

Comparing the photographs with the original hose is strongly recommended.

Condition

Used genuine Volkswagen part.

As a used hydraulic hose, it may show normal marks, staining, surface wear and traces of power steering fluid from previous installation.

Please inspect the supplied photographs carefully for the exact:

* Hose condition

* Connections

* Ends/fittings

* Clamps included

* Shape and length
