Power Steering Expansion Hose / Pressure Reducer for VW Vanagon T3 Gas (incl. Syncro) – OE Ref. 251422893C
Eliminate annoying steering noises and protect your steering rack!
This high-quality expansion hose (also known as a pressure reducer or dampening hose) is the crucial connecting piece between the power steering pump and the pressure line of your VW T3 Vanagon / Transporter. It is specifically designed for all T3 models with gasoline engines (Wasserboxer/WBX) – including the 4WD Syncro models.
Why is this expansion hose vital?
When locking the steering wheel to full extension, extreme pressure peaks build up inside the system. Without a functioning expansion hose, the pressure relief valves in the steering gear open abruptly, causing a loud, annoying whistling or buzzing noise. This hose reliably dampens those pressure spikes, quietens down the system, and protects the sensitive seals of your steering rack from premature wear and tear.
