Other T5 engines may also use this cooler, but compatibility should be confirmed using the OE number and original component.
Technical Information
The Volkswagen T5 uses hydraulic fluid to transfer assistance from the power steering pump to the steering system.
As the hydraulic fluid circulates through the system it generates and absorbs heat, particularly during:
* Repeated steering movements
* Low-speed manoeuvring
* Parking
* Urban driving
* Heavy vehicle operation
* Prolonged steering-system use
The 7H0422885D power steering cooler provides additional surface area to dissipate this heat before the hydraulic fluid continues circulating through the steering system.
Maintaining the correct fluid temperature helps protect the hydraulic steering components and contributes to consistent steering assistance.
Power Steering System Information
The cooler operates as part of the wider hydraulic steering circuit, which includes components such as:
* Power steering pump
* Power steering fluid reservoir
* Steering rack
* High-pressure hydraulic pipe
* Return hydraulic pipe
* Power steering oil cooler
* Connecting hoses
* Seals and O-rings
* Hydraulic power steering fluid
The cooler itself contains no electrical components and does not electronically control the steering system.
Common Reasons for Replacement
Replacement may be required because of:
* Hydraulic fluid leakage
* Corrosion
* Damaged cooler pipework
* Accident or frontal impact damage
* Bent cooler
* Damaged hose connections
* Cracked or deteriorated pipework
* Previous incorrect repair
* Excessive surface corrosion
* Damage during front-end repairs
Possible Symptoms of a Faulty / Leaking Cooler
Depending on the type of damage, symptoms can include:
* Power steering fluid underneath the vehicle
* Falling PAS fluid level
* Visible fluid around the cooler
* Wet or oily cooler pipework
* Power steering pump noise
* Whining when turning the steering wheel
* Reduced steering assistance if fluid becomes excessively low
* Frequent requirement to top up power steering fluid
A low power steering fluid level should be investigated promptly because continued operation can damage the hydraulic pump.
Important Diagnostic Information
Before replacing the cooler, inspect the complete hydraulic steering system for leaks.
Check:
* Power steering cooler
* Cooler connections
* Hydraulic hoses
* Hose clamps
* Power steering reservoir
* Power steering pump
* Steering rack
* High-pressure pipework
* Return pipework
* Seals and O-rings
Clean contaminated areas before diagnosis where possible, as leaking hydraulic fluid can travel along pipes and make the original leak difficult to identify.
Installation
This is a hydraulic mechanical component.
After installation, the power steering system should be filled with the correct Volkswagen-approved hydraulic fluid and correctly bled according to the appropriate workshop procedure.
Do not operate the power steering pump without sufficient hydraulic fluid.
All hose connections should be inspected for leaks after installation.
Programming / Coding
No programming or coding required.
This is a mechanical/hydraulic steering-system component.
Part Number / Revision Information
OE Number: 7H0422885D
VW Format: 7H0 422 885 D
Earlier related OE revisions include:
7H0422885
