Parts for your 2022 Mitsubishi Asx-Drive belt

2022 Mitsubishi ASX drive-belt: what it does and when to change it

Yes, the 2022 Mitsubishi ASX is fitted with an accessory drive-belt (serpentine belt). This is confirmed by factory workshop literature for the GA-series ASX/RVR/Outlander Sport (2019–2022) under Engine – Drive Belt inspection/adjustment, Mitsubishi Motors Australia’s ASX MY22 service schedule (drive-belt inspection at routine services), and major aftermarket catalogues that list a serpentine belt for the 2.0‑litre MIVEC engine. Note this model uses a timing chain for valve timing, but it still relies on a separate external drive-belt for the accessories.

On the 2022 ASX, the drive-belt’s job is to spin the alternator and A/C compressor (and, depending on variant, other ancillaries). When the belt is healthy, charging, cooling and comfort systems all play nicely. When it’s not, expect squeals on cold start, a battery light, poor A/C performance, or visible cracking and fraying.

Servicing-wise, the belt should be inspected at each service interval (typically every 12 months/15,000 km). Modern EPDM belts can last well over 100,000 km, but condition is king. Replace the belt if there are transverse cracks, chunks missing, glazing, or if the ribs look polished or uneven. It’s also smart practice to replace the automatic tensioner and any idler pulleys at the same time—worn pulleys can chew through a new belt quickly and cause noise.

A careful replacement is straightforward for a trained tech. They’ll confirm the belt routing, unload the tensioner with the correct tool, check pulley alignment, fit the new belt without twisting it, and run the engine to verify quiet operation and stable charging. Because the ASX uses electric power steering, a slipping belt won’t affect steering assist, but it can still leave the battery undercharged or the cabin warm if the A/C cuts out—so don’t ignore chirps or squeals.

For owners who like to keep things tidy between services, a quick visual check under good light helps: look along the ribbed side for cracks and listen for brief squeals on start-up. If any doubt, book it in—belts and tensioners are relatively inexpensive, and preventative replacement beats being stuck with a flat battery on a wet arvo.

• Inspect every 12 months/15,000 km
• Replace by condition, many last 100,000–150,000 km
• Renew tensioner/idlers with the belt for best results

Popular questions about the 2022 Mitsubishi ASX drive-belt

Does the 2022 ASX have a timing belt or chain?
It has a timing chain on the 2.0‑litre MIVEC engine. That chain handles valve timing and isn’t a routine replacement item. The vehicle still uses a separate accessory drive-belt (serpentine) for the alternator and A/C.

How often should the ASX drive-belt be replaced?
There’s usually no fixed kilometre change interval, it’s replaced based on condition. Have it inspected at every service (about 12 months/15,000 km). Many belts go 100,000–150,000 km, but cracks, glazing, chirps or charging/A/C issues mean it’s time.

What else should be replaced with the belt?
Best practice is to replace the automatic tensioner and any idler pulleys with the new belt. Fresh pulleys help the new belt run true and quiet, and reduce the chance of early wear or noise coming back.
