Parts for your 2014 Subaru Forester-Drive belt

2014 Subaru Forester drive-belt: what it does and when to replace it

Yes, a drive-belt is used on the 2014 Subaru Forester. Technical references that support this include the Subaru Forester SJ (2014) Factory Service Manual via Subaru’s Technical Information System (engine sections for FB25 and FA20F), Subaru’s parts catalogue listings for accessory/alternator and A/C belts, and aftermarket application data from Gates and Dayco. These sources show the petrol models run a serpentine accessory belt, while some diesel variants use two belts (including a stretch-fit A/C belt). On petrol engines, the water pump is driven by the timing chain, and the Forester uses electric power steering, so the drive-belt primarily runs the alternator and A/C compressor.

For everyday driving across Australia and New Zealand, the Forester’s EPDM accessory belt is a quiet achiever—keeping the battery charged and the cabin cool. It’s worth a look at every routine service (about every 12 months or 15,000 km). Most workshops recommend replacement around 90,000–120,000 km or 6–7 years, or earlier if there’s visible wear or noise. Diesel variants with a separate stretch-fit A/C belt have stricter rules: that A/C belt is single-use and requires the correct install tool.

What to watch and listen for:

• Chirps, squeals on cold start, or belt slip under load
• Cracks, fraying, glazing, missing ribs, or rubber dust around pulleys
• Battery warning light, dimming lights, or fluctuating voltage
• Intermittent A/C performance

Smart servicing tips for a 2014 Forester:

• Inspect the automatic tensioner and idler pulleys as a set, rough bearings or wobble will murder a new belt.
• Keep oil and coolant off the belt—contamination accelerates degradation.
• Confirm correct belt routing and rib alignment under the bonnet before starting.
• On diesel with a stretch A/C belt, don’t reuse it, fit a new belt with the proper tool.

Replacing the belt on petrol Foresters is typically a straightforward, under-an-hour job for a pro. It’s not a big-ticket item, and pairing it with a tensioner/idler refresh can save hassles later. If the belt fails, the alternator stops charging and the battery will discharge—so it’s best not to keep driving and to organise a repair promptly. Keeping this little loop of rubber healthy saves headaches and keeps the Forester ready for school runs, motorway hikes, and weekend tracks.

Popular questions

Does the 2014 Subaru Forester have a serpentine/drive-belt?
Yes. Petrol models use a single serpentine belt to drive the alternator and A/C compressor. Diesel variants can use two belts, including a stretch-fit A/C belt. Technical confirmation comes from the Subaru 2014 Forester service manual and parts catalogues, plus Gates/Dayco application data.

How often should the drive-belt be replaced in Australia or New Zealand?
Have it inspected at each service (about every 12 months or 15,000 km). Many workshops suggest replacement around 90,000–120,000 km or 6–7 years, sooner if there’s noise, cracking, glazing, or slip. Diesel A/C stretch belts are single-use and must be replaced whenever removed.

Can the Forester be driven if the belt breaks?
Not recommended. The alternator will stop charging and the battery will go flat, which can leave the vehicle stranded. If only a separate A/C belt fails on a diesel, you may keep moving but you’ll lose air-con—still best to repair promptly.
