Parts for your 2017 Subaru Exiga-Drive belt

2017 Subaru Exiga drive belt: what it does and when to change it

For the 2017 Subaru Exiga (often sold as the Exiga Crossover 7), a drive belt is very much relevant and fitted. Subaru’s FB25 engine used in this model drives the alternator and air-conditioning compressor via a V‑ribbed (serpentine) auxiliary belt. This is documented in Subaru’s FB25 Engine Service Manual (Subaru Technical Information System), which includes inspection and replacement procedures for the V‑ribbed belt and automatic tensioner, and in Subaru parts catalogues for the Exiga Crossover 7 that list the alternator/A/C “V‑belt” as a service part. Owner’s maintenance schedules also call for periodic inspection of the engine drive belt.

This belt’s job is straightforward but critical: it spins the alternator to keep the battery charged and powers the A/C compressor for cabin cooling. The Exiga uses electric power steering, so there’s no hydraulic power steering pump on the belt, but losing belt drive still risks a flat battery and warm air from the vents.

For local conditions in Australia and New Zealand, it’s smart practice to have the drive belt inspected at every scheduled service (typically every 12 months or 15,000 km). Heat, dust, and stop–start use can age rubber faster, so most workshops replace the belt on condition rather than a strict kilometre figure. Many owners see replacement somewhere around 80,000–120,000 km, but earlier if wear is present. The FB-series uses an automatic tensioner, even so, belts stretch and the ribs can harden or crack over time.

• Watch for belt squeal or chirp at cold start.
• Check for glazing, cracking, fraying, rib chunking, or oil contamination.
• Note battery warning lights, dim lights, or A/C that cuts out under load.

When a belt is due, a quality OEM-spec V‑ribbed belt should be fitted, and it’s wise to assess the tensioner and idler pulleys for smooth bearings and proper spring tension at the same time. Any coolant or engine-oil leaks under the bonnet should be sorted, as fluids shorten belt life. Correct routing and clean, dry pulleys help prevent noise and premature wear. A quick test run after replacement to verify quiet operation and proper charging voltage is good workshop practice. Keeping a record of belt condition and replacement date makes future servicing simple and avoids unexpected dramas on a long trip.

Does the 2017 Subaru Exiga have a drive belt?

Yes. The FB25-powered Exiga uses a V‑ribbed auxiliary belt to drive the alternator and A/C compressor. Power steering is electric, so it’s not belt-driven.

How often should the Exiga’s drive belt be replaced?

It’s inspected at every service and replaced on condition. In Aussie and Kiwi conditions, many workshops see replacement around 80,000–120,000 km, sooner if there’s noise, cracking, or glazing.

What are common signs the belt needs attention?

Cold-start squeal or chirp, visible cracks or fraying, shiny/glazed ribs, battery warning lights, dimming lights, or A/C performance dropping under load all point to belt or tensioner wear.
