Parts for your 2013 Subaru Exiga-Power steering pump

2013 Subaru Exiga power steering pump — what it does and how to look after it

On the 2013 Subaru Exiga (YA series), a belt‑driven hydraulic power steering pump is fitted and very much relevant. Subaru’s Exiga YA Service Manual (Steering > Power Assisted System), the Subaru FAST electronic parts catalogue for YA models, and the 2013 JDM brochure (which lists “hydraulic power steering”) all confirm this setup. So, yes — there’s a conventional pump on the front of the engine doing the assist work.

The pump’s job is simple but crucial: it pressurises fluid and feeds the steering rack so low‑speed parking and tight turns don’t feel like a gym workout. When it’s healthy, steering is smooth, quiet and nicely weighted. When it’s not, drivers may notice a whining noise, heavier effort at the wheel, or aerated/foamy fluid in the reservoir.

As part of routine servicing, the Exiga benefits from basic pump and fluid care. Fluid level and condition should be checked at each service. Subaru specifies power steering fluid based on Dexron III ATF characteristics (or Subaru‑branded equivalent) — don’t top up with CVT fluid or generic “stop‑leak” products. If the fluid is dark, smells burnt, or shows metallic sparkle, plan a flush and inspection.

Because the pump is belt‑driven, a quick look at the drive belt for glazing, cracking or poor tension is smart. Hoses and the pump’s inlet O‑ring can harden with age, allowing air to sneak in and cause that classic Subaru steering whine. Replacing hardened O‑rings and perished return hoses is an inexpensive, high‑value fix.

When replacing the pump, many workshops choose a quality remanufactured unit with new seals and bearings. Allow around 1–2 hours labour depending on access. Use new sealing washers where required and observe torque specs. After any work, bleeding matters: with the engine off, turn the wheel lock‑to‑lock slowly 15–20 times, top up, then run the engine briefly, recheck level, and repeat until the fluid runs clear and bubble‑free.

Top tips for long pump life on a 2013 Exiga:

• Refresh fluid every 60,000–80,000 km in tougher conditions, or when discoloured.
• Keep the reservoir screen clean and the cap seal intact to limit contamination.
• Fix leaks early — low fluid can quickly score pump vanes and bearings.
• Avoid holding full lock for more than a few seconds, it spikes pressure and heat.

Popular questions about 2013 Subaru Exiga power steering pumps

Does the 2013 Exiga use electric or hydraulic power steering?
It uses hydraulic assist with a belt‑driven pump. This is documented in the Exiga YA Service Manual and the Subaru FAST parts catalogue for YA5/YA9 models, which list a pump assembly and related hydraulic components. The 2013 JDM brochure also notes hydraulic power steering.

What fluid should be used, and how much?
Use Subaru‑approved power steering fluid meeting Dexron III ATF characteristics. Don’t mix with CVTF or green mineral CHF fluids. A typical drain and refill consumes around a litre, a more thorough flush may take a bit more to ensure the return runs clean and bubble‑free.

What are the common signs the pump is failing?
Common hints include a whining sound that gets louder on cold starts or when turning, heavier steering at low speed, fluid aeration (foam) in the reservoir, and visible leaks at hoses, fittings or the pump shaft. Addressing suction‑side O‑rings and return hoses often cures aeration before a full pump swap is needed.
