2012 Subaru Exiga Power Steering Hose — What It Does and When to Replace It

Based on technical references, the 2012 Subaru Exiga (YA series) is equipped with a conventional hydraulic power steering system that uses both a high‑pressure hose and a low‑pressure return hose. The Subaru Exiga Service Manual (Steering/PAS section for YA models) details a belt‑driven vane pump feeding the steering rack via a pressure hose, and the Subaru FAST electronic parts catalogue lists distinct part numbers for the pressure and return hoses for MY2012 Exiga variants. Major aftermarket catalogues for Australia and New Zealand (e.g., Gates/Dayco/Ryco) also specify replacement pressure hoses for the 2012 Exiga. So yes — a power steering hose is absolutely relevant and fitted to this vehicle.

The power steering hose’s job is to move fluid between the pump, reservoir and steering rack. The pressure hose handles pump output at high pressure, while the return hose channels fluid back to the reservoir. Healthy hoses mean quiet operation, light steering effort, and minimal pump wear.

For ongoing servicing, it’s smart to inspect the hoses every service interval. Look for soft spots, cracking, sweating around crimps, or damp areas at the banjo fittings. Use the fluid type specified by Subaru for this era (an ATF‑type power steering fluid meeting Dexron III is commonly specified, always check the owner’s manual). Contamination or low fluid will cook a pump faster than you can say spanner.

• Common symptoms of hose issues: heavy steering at idle, whining from the pump, spots of red/brown fluid under the nose, or a burnt‑fluid smell after a long drive.
• Replace crush washers on banjo bolts and any perished clamps or O‑rings when a hose is changed.
• Avoid twisting the hose during fitment, support the rack and lines to prevent stress at the fittings.

When replacement’s due, a quality OEM‑equivalent hose with correct crimped ends is the go. After installation, bleed the system: front wheels off the ground, engine off, turn lock‑to‑lock slowly a dozen times, top up, then start and repeat until bubbles are gone. Re‑check for leaks after a short drive. On vehicles 10+ years old, proactive replacement of a weeping pressure hose can save the pump and rack — a tidy bit of preventative maintenance for Aussie and Kiwi conditions.

Popular questions about 2012 Subaru Exiga power steering hose

Does the 2012 Exiga use electric power steering?
No. The 2012 Exiga uses a hydraulic power steering system with a belt‑driven pump and hoses. That’s why you’ll find both a high‑pressure feed hose and a low‑pressure return hose under the bonnet. If the steering feels heavy or noisy, hoses and fluid are key places to check.

What fluid should be used after hose replacement?
Use the fluid grade specified by Subaru for this model year — typically an ATF‑type fluid meeting Dexron III. Don’t mix in universal fluids unless they explicitly meet the Subaru specification. After refilling, bleed the system thoroughly to avoid pump whine and aeration.

How much does hose replacement usually cost?
Costs vary by engine variant and local labour rates, but as a ballpark in AU/NZ: a quality pressure hose can run a few hundred dollars, plus 1–2 hours labour and about a litre of fluid. Expect more if seized fasteners or additional seals need attention.
