Parts for your 2011 Subaru Exiga-Drive belt

2011 Subaru Exiga drive belt — what it does and when to replace it

Yes, a drive belt is absolutely used on the 2011 Subaru Exiga. Subaru’s factory service information for the YA-series Exiga (2008–2012) and the Subaru Electronic Parts Catalogue both show V‑ribbed accessory drive belts fitted to 2.0‑litre EJ engines, running the alternator, power steering pump and air‑conditioning compressor. The 2011 owner’s manual also lists drive belt inspection as a routine maintenance item.

On a 2011 Exiga, the drive belt setup is typically two belts on the EJ20 engine: one belt for the alternator and power steering, and a separate belt for the A/C compressor. Their job is simple but critical—convert crankshaft rotation into the essentials that keep the car happy on the daily run.

• Alternator: keeps the battery charged and the electrics stable.
• Power steering pump: gives light, predictable steering feel.
• A/C compressor: delivers cold air when summer hits.

For Aussie and Kiwi conditions, it’s smart to have the belts checked at every scheduled service (typically every 12 months or around 12,500–15,000 km). Heat, dust and stop‑start use age belts faster. Replacement is usually condition‑based, but many owners see best results swapping belts somewhere around 60,000–100,000 km or at 5–7 years, whichever comes first.

• Watch for squeals on cold start, chirps when you flick the A/C on, or a flickering charge light.
• Under the bonnet, look for cracks, fraying, glazing (shiny ribs) or rubber dust around the pulleys.
• If steering suddenly feels heavy or the battery goes flat after a squeal, a slipping or snapped belt could be the culprit.

When replacing, use quality V‑ribbed belts sized for the Exiga’s EJ20. Inspect pulleys and tensioners, set tension correctly (over‑tight belts can kill bearings, loose belts will squeal), and recheck after a few hundred kilometres. Most 2011 cars run the EJ20 with two belts, a quick VIN or under‑bonnet check will confirm the layout. A competent tech can swap them quickly, and it’s a low‑cost way to protect charging, steering feel and cabin comfort.

Popular questions about 2011 Subaru Exiga drive belts

Does a 2011 Exiga have one serpentine belt or two?
Most 2011 Exiga models with the EJ20 have two V‑ribbed belts: one for alternator/power steering and another for the A/C compressor. A quick glance under the bonnet will show two separate belts and pulleys. If unsure, confirm by VIN against the Subaru parts catalogue.

How often should the drive belts be replaced?
Inspect at every service. Many owners replace belts around 60,000–100,000 km or at 5–7 years, but go by condition—cracks, glazing, noise or poor accessory performance mean it’s time.

Is it safe to drive with a squealing belt?
Not recommended. A slipping belt can leave the alternator under‑charging and the steering heavy if the power steering belt is affected. The EJ20’s water pump is driven by the timing belt, not the accessory belts, but you can still end up stranded with a flat battery. Sort it promptly.
