Nissan Navara 2.5 dCi Timing Chain Replacement

Which vehicles does this cover?

This covers the 2.5 dCi (YD25DDTI) diesel engine fitted across the Nissan Navara D40 pick-up and its close relative the Pathfinder R51. Registration/VIN confirmation required before booking, as this generation spans several years of production.

Driving a newer NP300 Navara? That's a different engine (2.3 dCi) — send us your registration and we'll confirm the correct job before you book.

Signs your 2.5 dCi timing chain needs attention

• A rattling or ticking noise from the front of the engine, especially on cold start-up
• Engine management light with a timing-related fault code
• Rough running, hesitation or a noticeable loss of power
• In advanced cases, the chain jumping timing causes serious internal engine damage

Why this job takes around 8 hours

Unlike a straightforward front-of-engine chain job, the duplex timing chain on the 2.5 dCi sits behind the front-end assembly — the radiator support panel and timing cover have to come out before the chain, tensioner and guides are even accessible. That strip-down and rebuild time is why this is priced and scheduled as a full day's specialist work, not a same-morning job.

Our replacement process

1. Registration/VIN confirmation of your exact 2.5 dCi specification.
2. Fixed price confirmed before any work begins.
3. Front-end support panel and timing cover removed for access.
4. Duplex timing chain, tensioner, guides and sprockets replaced with correctly specified components.
5. Full timing verification to confirm correct cam/crank alignment.
6. Oil and filter change included, front-end rebuilt and road tested.
