Maintenance
Follow the handbook and confirmed engine specification; maintain fluids, belts, hoses, cooling components and fuel-system parts according to condition and documented servicing.
Engine overview · 2.6L 6-cyl PETROL
A smooth, conventional six-cylinder engine with good durability potential, but age-related cooling, sealing, fuel-injection and timing-chain condition is now central to ownership.
Pros
- Smooth naturally aspirated six-cylinder character.
- No turbo or hybrid hardware.
- Well-understood conventional mechanical layout.
Cons
- Age-related maintenance can be substantial.
- CIS-E fuel injection needs informed servicing.
- Cooling neglect can become costly.
