Nissan LEAF (ZE0) 2010- Electric Auto Engine Parts K21 K25 2.5D Cylinder Head 11040FY501 Forklift Carrelli 2.1L 2.5L – OEM 11040FY501

Product Overview: This complete cylinder head assembly is manufactured for the Nissan K21 and K25 2.1 and 2.5-litre industrial diesel engines, the durable powerplants widely used in forklifts and material-handling equipment. It is supplied fully assembled with valves included and machined to original equipment dimensions, making it a practical replacement for a warped, cracked 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 installed and honed for even sealing and balanced compression, and the injector seats and valve ports are precision machined to maintain correct combustion. Machined intake and exhaust flanges ensure reliable gasket sealing, while reinforced casting around the fire deck improves durability under the sustained load typical of industrial diesel operation.

Vehicle Compatibility: This head suits Nissan K21 and K25 industrial diesel engines used in forklift trucks and material-handling machinery. Catalogue references also associate this unit with the LEAF (ZE0) platform listing, so always confirm the engine code, casting number and OE reference against the original component before ordering.

Specifications: Engine code K21 / K25; displacement 2.1 L and 2.5 L; industrial diesel; standard size; new condition; valves included; complete assembly; 12-month warranty; intended for replacement and repair.

OEM / Reference Numbers: 11040FY501. Cross-reference this number with the casting marks and part label on the original cylinder head to confirm the correct specification is supplied.

Applications: Suitable for forklifts, industrial and material-handling equipment, small commercial machines and utility engines, covering workshop overhauls, engine rebuilds and preventive maintenance programmes that require a durable factory-specification head.

Benefits / Replacement Information: Installing this assembly restores compression, corrects coolant loss and combustion leakage caused by cracks or distortion, and avoids the expense of re-machining the original casting. A complete unit shortens equipment downtime and delivers factory-matched sealing.

Installation or Fitment Notes: Installation should be carried out by a qualified technician. Clean and check the block deck for flatness, fit a new head gasket and new head bolts where specified, and torque in the correct sequence to the manufacturer's specification. Verify valve clearances and injection timing during reassembly, then pressure test and bleed the cooling system before returning the engine to service.
