Parts for your 2023 Mitsubishi Eclipse cross-Timing belt kit

2023 Mitsubishi Eclipse Cross timing-belt-kit — do you need one?

A timing-belt-kit is not used on the 2023 Mitsubishi Eclipse Cross. Both the 1.5‑litre MIVEC turbo-petrol and the Eclipse Cross PHEV’s 2.4‑litre MIVEC engines are built with a timing chain, not a timing belt, so there’s no belt kit to replace or fit.

This isn’t guesswork — it’s supported by technical literature and parts catalogues. The Mitsubishi Motors service manuals for the 1.5T (4B40) and 2.4 MIVEC (PHEV) engines specify a chain-driven camshaft system. Major aftermarket catalogues that list belt kits (like Gates Australia/NZ and Dayco) do not list a timing-belt kit for the 2018–on Eclipse Cross petrol or PHEV and note a chain cam drive. Workshop data platforms such as Autodata also describe the cam drive as a chain with no scheduled belt replacement interval.

Why no belt? Mitsubishi designed these engines with a chain for durability and reduced lifetime servicing. A timing chain runs inside the engine with constant oil lubrication, making it more robust than a rubber belt for long-term use. Unlike belts, chains generally don’t have a fixed replacement interval, they’re intended to last the life of the engine when serviced correctly. That means owners aren’t budgeting for a 90,000–150,000 km belt change — a common cost on belt-driven engines.

While there’s no timing-belt-kit to worry about, the chain still appreciates good care. Quality oil and on-time services are key: dirty or degraded oil can accelerate wear of the chain, guides, and hydraulic tensioner. If the vehicle develops a rattle on cold start, fault codes for cam/crank correlation, or poor running, it’s worth getting a technician to check chain stretch and the condition of the guides and tensioner. Genuine or reputable OE‑quality parts should be used if any chain components ever need attention, but that’s uncommon on well-serviced cars.

• Service on schedule with the correct oil spec and grade for Australia/NZ conditions.
• Listen for abnormal chain noise at cold start and under light throttle.
• Address oil leaks promptly and avoid extended drain intervals.

Popular questions

Does the 2023 Mitsubishi Eclipse Cross have a timing belt or a chain?
It has a timing chain. Mitsubishi specifies a chain-driven cam system for both the 1.5‑litre turbo and the PHEV’s 2.4‑litre engine, so there’s no timing belt to replace.

Is there a timing-belt replacement interval on a 2023 Eclipse Cross?
No. Because it uses a chain, there is no belt replacement interval. The chain is designed to last the life of the engine when serviced correctly. Stick to the service schedule and correct oil to help keep the chain, guides, and tensioner happy.

What maintenance helps the timing chain last on an Eclipse Cross?
Regular oil changes with the specified grade, avoiding extended intervals, and using quality filters are the big ones. If you ever notice cold-start rattles or timing-related fault codes, get it checked early to prevent knock-on wear.
