Nissan NAVARA NP300 ( 2016 - 2021 ) 2014-2023 YD25 Top Quality Cylinder Head YD25 YD22 Navara Frontier NP300 Pathfinder X-Trail OEM 11040-5M300 11040-5M301 2.5DDTI – OEM 908510

Product Overview: This top-quality cylinder head assembly is manufactured for the Nissan YD25 and YD22 2.5-litre turbo-diesel engines, the powerplants fitted to the Navara, Frontier, NP300, Pathfinder and X-Trail. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment tolerances, offering a durable replacement for a cracked, warped or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade material and CNC-machined for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume. Valve guides and seats are pre-installed and honed for even sealing and balanced compression across all four cylinders, and the cam carrier surfaces are finished to maintain correct bearing clearance. Injector bores and glow plug threads are precisely machined for correct common-rail diesel fitment, while reinforced casting around the valve bridge and fire deck improves durability under turbo-diesel cylinder pressures.

Vehicle Compatibility: This head fits Nissan Navara NP300 (2014-2023), Hardbody (2006 onwards), Tiida (2007 onwards), Murano (2004-2015), Note UK Make (2006-2016) and Micra (1992-2010) models, plus related Frontier, Pathfinder and X-Trail applications that use the YD25 or YD22 engine. Confirm the engine code and OE reference before ordering.

Specifications: Engine code YD25 / YD22; displacement 2.5 litres; inline four-cylinder turbo-diesel; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; purpose replacement and repair.

OEM / Reference Numbers: 908510, 908505, 11040-BN360, 11040-EC00C, 11039-EB30A, 11039-EC00A, 11040-EB300, 11040-5X00A, 11040-5M302, 11040-5M301 and 11040-5M300. Cross-reference these numbers with the casting marks on the original head.

Applications: Suitable for pickups, SUVs, vans and light commercial vehicles, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a durable factory-specification diesel head is required.

Benefits / Replacement Information: Fitting this assembly restores compression, corrects coolant and combustion leakage caused by cracking or distortion, and removes the downtime and cost of reconditioning the original casting. A complete unit ensures matched valve and seat geometry for dependable long-term sealing.

Installation or Fitment Notes: Installation should be performed by a qualified technician. Verify block deck flatness, fit a new head gasket and new head bolts where specified, and torque in the correct sequence to the manufacturer's specification. Check valve clearances and injection timing after assembly, then pressure test and bleed the cooling system before road use.
