Parts for your 2009 Subaru Exiga-Power steering hose

2009 Subaru Exiga power‑steering hose: what it does and how to look after it

Yes, the 2009 Subaru Exiga uses a hydraulic power steering system with dedicated hoses. This is supported by Subaru’s YA‑series Service Manual (Steering section), which details a belt‑driven vane pump feeding the steering rack via high‑pressure and return hoses, the Subaru FAST electronic parts catalogue (Group 34 – Steering) lists the pressure and return hose assemblies for Exiga YA models, and the factory Owner’s Manual specifies ATF (Dexron III) as the steering fluid, indicating a hydraulic setup rather than electric power steering.

On this Exiga, the power‑steering hose set carries fluid between the pump, reservoir and steering rack. The high‑pressure hose takes fluid from the pump to the rack under serious pressure, while the return hose brings it back to the reservoir at low pressure. Together they keep steering light and consistent at parking speeds and steady on the motorway.

With age, heat and Kiwi/Aussie conditions, hoses can harden, sweat or crack. Telltale signs include a red or brown oily film on the subframe, a pump whine on cold starts, heavy steering at idle, or damp hose crimps. If left too long, a split hose can dump fluid, glaze the drive belt and make the wheel a workout.

Good servicing habits make a big difference:

• Inspect hose rubber, crimps and clamps every 40,000–60,000 km or annually on older cars.
• Keep the reservoir at the correct mark with ATF Dexron III, don’t mix random fluids.
• After any hose replacement, fit new sealing washers/O‑rings, torque banjo bolts correctly and flush the system.

Bleeding is straightforward: with the front tyres off the ground and engine off, turn lock‑to‑lock 10–20 times, top up fluid, then start briefly and repeat until bubbles clear. Keep fluid off belts and under‑bonnet paint, and recycle waste fluid properly.

Given the Exiga’s 2009 build, many original hoses are now at end of life. A proactive replacement of the pressure hose (and the softer return hose if spongy) restores feel and protects the pump and rack. A competent workshop will typically allow 1–2 hours, depending on access around the pump and rack. Genuine or quality aftermarket hoses both do the job, what matters is correct routing and heat shielding near the exhaust. It’s a simple bit of plumbing that keeps the big Subaru steering sweet every day.

Popular questions

How can an owner spot a failing power‑steering hose on a 2009 Exiga?
Look for dampness around hose crimps, red/brown fluid on the crossmember, or drops under the front after parking. A groaning or whining pump on cold mornings or a steering wheel that goes heavy at idle are common clues. If the fluid level keeps dropping, the hose set and clamps deserve a close look.

What power‑steering fluid does the Exiga take?
Subaru specifies ATF meeting Dexron III for the Exiga’s hydraulic steering. Sticking to that spec keeps seals happy and pump noise down. Avoid mixing with universal power‑steering fluids unless they clearly state Dexron III compatibility, and if in doubt, flush and refill with fresh fluid.

Does the 2009 Exiga use electric power steering?
No. The 2009 Exiga runs a hydraulic system with a belt‑driven pump and hoses. Later Subaru platforms moved to electric assist, but the YA‑series Exiga retains traditional hydraulic assist, which is why hose condition and fluid quality matter on servicing.
