Parts for your 2009 Subaru Impreza-Power steering hose

2009 Subaru Impreza Power Steering Hose

According to Subaru’s 2009MY Impreza Service Manual for GE/GH chassis (Steering – Power Assisted Steering, Hydraulic) and the Subaru electronic parts catalogues (FAST/STIS) listing dedicated high-pressure and return hose assemblies for 2008–2011 Impreza/WRX/STI, the 2009 Subaru Impreza uses a hydraulic power steering system with power‑steering hoses. So a power‑steering hose is absolutely relevant and serviceable on this model.

On a 2009 Impreza, the power‑steering hose set carries hydraulic fluid between the pump, reservoir and steering rack. The high‑pressure hose takes fluid from the engine‑driven pump to the rack, while the return hose brings it back to the reservoir. Together they help deliver that light, predictable steering feel drivers expect around town and on the open road across Australia and New Zealand.

With age, heat and constant pressure, hoses can go hard, sweat, or seep. If the steering starts to feel heavy, the pump whines on lock, or there’s reddish fluid under the bonnet or on the subframe, it’s time for a look. A quick inspection during regular servicing—checking for cracks, dampness at crimps, and perished clamps—can save a pump or rack from premature wear.

When replacement’s due, it pays to fit quality OEM‑spec hoses and new sealing washers on banjo fittings. Use the correct fluid for the VIN (commonly a Dexron III‑equivalent ATF on this generation, as specified by Subaru), don’t mix fluid types, and always bleed the system properly: wheels off the ground, engine off at first, turn lock‑to‑lock slowly to purge air, top up, then repeat with the engine idling. Keep an eye out for foaming or aeration—signs there’s still air or a suction leak on the return side.

Heat management matters, especially on turbo variants where the hose runs near hot hardware. Make sure any factory heat shields and clips are refitted in the original routing. Avoid overtightening hard‑line unions, crushing a flare or twisting the rack fitting invites leaks. There’s no fixed replacement interval, but a simple check every service and proactive replacement at the first sign of deterioration is a smart, cost‑effective move for keeping the Impreza’s steering light, quiet and reliable for many more kilometres.

• Common signs of trouble: heavy steering, pump whine, fluid spots, low reservoir level, burnt‑smelling fluid.
• Good practice: inspect at each service, use correct fluid, replace crush washers, and bleed thoroughly.

FAQs

Does a 2009 Subaru Impreza have electric or hydraulic power steering?
For 2008–2011 Impreza models (GE/GH), Subaru used a hydraulic system with an engine‑driven pump and hoses. Electric power steering arrived on the next‑gen Impreza from 2012. So the 2009 car definitely has power‑steering hoses.

What fluid should be used in the 2009 Impreza’s power steering?
Subaru specifies an ATF‑type fluid for this generation—commonly Dexron III‑equivalent. Check the reservoir cap and owner’s manual for the exact call‑out for the vehicle’s VIN, and avoid mixing fluid types.

How much does replacing a power‑steering hose typically cost?
In Australia, parts and labour usually land around AUD $300–$800 depending on hose (pressure vs return), brand and access time. In New Zealand, expect roughly NZD $350–$900. Prices vary by workshop rates and parts choice.
