2009 Subaru Forester Power Steering Hose — What It Does and When To Replace It

Yes, a power steering hose is absolutely relevant on the 2009 Subaru Forester (SH). Technical references such as the Subaru Factory Service Manual for the 2009MY Forester (Steering section) and the Subaru electronic parts catalogue show a conventional hydraulic power steering system with a belt-driven pump, a high-pressure hose from the pump to the rack, and a low-pressure return hose. This model does not use electric power steering, so hoses are essential to move fluid and create assist.

On this Forester, the power steering hoses do the heavy lifting behind the scenes. The high-pressure line carries pump output to the rack at substantial pressure, while the return hose brings fluid back to the reservoir. Together they provide smooth, light steering feel at parking speeds and steady control on the open road. They run close to heat sources under the bonnet and put up with vibration, so over time the rubber, crimps, and seals can harden, sweat, or leak.

Good servicing habits go a long way. At each service, have the hoses checked for sweating, cracks, soft spots, chafing, and dampness at crimps or fittings. Also check fluid level and condition, Subaru’s documentation for this era specifies ATF meeting Dexron III for the power steering—always confirm on the reservoir cap or owner’s manual. Many workshops recommend refreshing fluid every 60–100,000 kilometres to keep the pump and rack happy in Aussie and Kiwi climates.

• Common symptoms of hose trouble: heavy steering, pump whine, aerated/foamy fluid, reddish stains under the vehicle, or a burning smell if fluid hits hot components.
• Preventative tips: keep correct belt tension, ensure proper hose routing and heat shielding, and replace aged clamps on the return line.

1. When replacing a hose, use quality OEM or equivalent, and new sealing washers/O-rings where specified.
2. Torque fittings to the workshop manual spec—over-tightening can damage racks or banjo fittings.
3. Bleed the system: with the front wheels off the ground and engine off, turn lock-to-lock slowly 15–20 times, topping up as bubbles clear. Then start briefly, recheck level, and inspect for leaks.
4. Wipe up spills—ATF can damage rubber and paint, and it’s slippery on belts.

Look after the power steering hoses on a 2009 Forester and the steering stays light, quiet, and dependable for many more kilometres.

Popular questions

Does the 2009 Subaru Forester use electric steering or hydraulic hoses?
It’s hydraulic. Subaru’s workshop manual and parts listings for the 2009 Forester (SH) show a belt-driven power steering pump feeding the rack via a high-pressure hose with a separate return line. There’s no electric power steering on this model, so hoses are a must.

What fluid should go in the 2009 Forester power steering system?
For this model year, Subaru specifies an ATF that meets Dexron III for the power steering system. Always double-check the reservoir cap and the owner’s manual, and avoid mixing fluid types. If in doubt, drain and refill with the correct spec.

When should the power steering hose be replaced?
There’s no fixed interval, but replace at the first sign of sweating, cracking, leaks at crimps, steering heaviness, or persistent pump noise. In hot climates or higher-mileage vehicles, proactive replacement of an ageing pressure hose can prevent a sudden leak.
