Engine overview · 4.0L 6-cyl PETROL
The GSJ10 FJ Cruiser’s 4.0-litre petrol V6 is generally durable, although age, maintenance, off-road exposure and differences between applications strongly influence ownership condition.
Pros
- Durable naturally aspirated V6 character
- Timing chain rather than a scheduled timing belt
- Well-supported servicing and parts availability
Cons
- Cooling-system leaks can develop with age
- Some engines may produce timing-chain noise
- Oil or exhaust leaks can become labour-intensive repairs
Common problems & ownership concerns

- Cooling-system leaks on ageing enginesMedium
- Cold-start timing-chain noise on applicable enginesMedium
- Oil leaks from seals or coversLow
- Exhaust manifold or front-exhaust deteriorationMedium
Maintenance
Follow the market-specific manual and VIN-specific schedule, with regular attention to coolant condition, leaks, timing-chain noise and off-road contamination.
