NISSAN INTERSTAR Bus 2003.11- dCi 140 (100KW,136PS) 11039-VZ20A 7701458028 11039-VC10A ZD30 Cylinder Head ZD30-DDTI – OEM 11039-VC10A

Product Overview: This complete cylinder head assembly is manufactured for the Nissan ZD30 3.0-litre four-cylinder turbo-diesel engine, a robust powerplant used in the Interstar bus and van, NT500 truck and related Renault and Opel commercial platforms. It is supplied fully assembled with valves, guides and seats installed and machined to original equipment dimensions, making it a dependable 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 for correct bearing clearance. Injector bores and glow plug threads are precisely machined to suit common-rail components, while reinforced casting around the valve bridge and fire deck improves thermal durability under sustained commercial duty.

Vehicle Compatibility: This head fits Nissan Interstar Bus dCi 140 (2003 onwards, 100 kW / 136 PS), Interstar Van and Platform/Chassis dCi 140, and NT500 35.15 and 35.15 HD (2013 onwards, 110 kW / 150 PS), plus Renault Master Pro Platform/Chassis and related Opel applications that use the ZD30 engine. Confirm the engine code and OE reference before ordering.

Specifications: Engine code ZD30; displacement 3.0 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: 11039-VC10A, 11039-VC101, 11039-VC10B, 11039-VZ20C, 11039-VZ20B, 11039-VZ204, 908506, 908509, 7701058028, 7701458028 and 11039-VZ20A. Cross-reference these numbers with the casting marks on the original head.

Applications: Suitable for buses, vans, chassis-cab trucks and commercial fleets, covering everyday repairs, engine rebuilds, workshop overhauls and preventive maintenance programmes that require a durable factory-specification diesel head.

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 keeps commercial vehicles in service with minimal interruption.

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 returning the vehicle to service.
