Common Failure
Early reports indicate the 1.3-litre turbo engine (also used in Renault Captur, Mercedes-Benz A-Class/GLA/GLB) can suffer from timing chain stretch, particularly if oil change intervals are extended. The engine uses a timing chain with a recommended oil spec of 5W-40 . Coolant leaks from the turbocharger cooling system and DPF-related issues in some variants have also been noted [THIRD-PARTY].
The Mitsubishi ASX 1.3 turbo (H5H 490) is a modern Renault-sourced engine with a timing chain, but it has known weak points that can drive replacement decisions: timing chain stretch, turbocharger cooling issues, and potential overheating. Rebuilt engines through EnginesMarket include upgraded components addressing these failure points, plus a minimum 12-month unlimited-mileage warranty.

Extended oil change intervals or using incorrect oil viscosity (5W-40 is recommended) can lead to chain stretch and tensioner failure [EM-INTERVIEW]. Early warning signs include rattling noise on cold start-up and check engine lights.

Vehicle Value Check
Vehicle Value Check
A typical 2023-2025 ASX 1.3 turbo is worth approximately £15,000-£25,000, with newer models retaining higher value [INDUSTRY ESTIMATE]. - Vehicle worth under ~£10,000: repair or used engine typically makes more sense than a full rebuilt unit. - Vehicle worth ~£10,000-£18,000: evaluate both; reconditioned is viable if keeping the car 2+ years. - Vehicle worth ~£18,000-£25,000: reconditioned/rebuilt usually justifies the premium via warranty and reliability. - Vehicle worth £25,000+: replacement cost is typically small relative to vehicle value.
Our Recommendation
Our Recommendation
For a modern ASX 1.3 turbo, preventative timing chain replacement is strongly recommended when cold-start rattle appears - £800-£1,200 is far cheaper than a full engine replacement. Insist on the correct 5W-40 oil spec and avoid extended oil change intervals [EM-INTERVIEW].

Question 2What are the signs of timing chain failure in a Mitsubishi ASX 1.3 turbo-
Symptoms include a rattling noise on cold start-up that may disappear as the engine warms, a check engine light with timing-related fault codes, and in severe cases, engine misfire or loss of power. The 1.3-litre turbo uses a timing chain with a hydraulic tensioner - if the tensioner loses pressure, the chain can stretch [EM-INTERVIEW].
- Rattling noise on cold start-up
- Check engine light with timing fault codes
- Engine misfire or loss of power
Question 3Is it worth replacing the engine in a Mitsubishi ASX 1.3 turbo-
A full rebuilt H5H 490 engine costs around £2,000-£3,800 supply-only [ESTIMATED]. For a 2023-2025 ASX worth £15,000-£25,000, replacement is typically financially sensible - especially with a 12-month warranty. Always factor in labour (£390-£520) and the value of the car.
- 2023-2025 values £15,000-£25,000: replacement viable
- Always factor in labour and warranty value
Question 4How long does a Mitsubishi ASX 1.3 turbo engine replacement take-
A specialist workshop typically completes a full H5H 490 engine swap in 8-10 hours. With parts sourcing and delivery factored in, allow 2-3 days from quote to car back on the road. Supply & fit options through EnginesMarket streamline the process by pairing you with a specialist who has the engine in stock.
- 8-10 hours specialist labour
- 2-3 days typical turnaround
- Supply & fit options available
Question 5What's the difference between the Mitsubishi ASX 1.3 turbo and the previous 2.0-litre/2.4-litre ASX-
The second-generation ASX (2023-present) is completely different from the previous model - it's built on the Renault CMF-B platform alongside the Captur, not in Japan . The 1.3-litre turbo engine produces 113-116kW and 270Nm, offering better fuel efficiency and more torque than the old 2.0-litre (110kW/197Nm) . The new ASX is also more expensive, reflecting its European build quality .
- 2nd-gen ASX: Renault-based, 1.3-litre turbo, 113-116kW/270Nm
- Previous ASX: Japanese-built, 2.0/2.4-litre naturally aspirated
- New model more premium with better torque
Question 6Does the Mitsubishi ASX 1.3 turbo have a timing belt or chain-
The Mitsubishi ASX 1.3 turbo (H5H 490) uses a timing chain, not a belt . This is confirmed by parts suppliers and workshop literature. The chain does not have a routine replacement interval, but can stretch on higher-mileage examples - particularly if oil changes are neglected. Use the correct 5W-40 oil specification to extend chain life .
- Timing chain, not belt
- No routine replacement interval
- Use 5W-40 oil specification
