ISUZU D-MAX I 2007.01-2012.06 3.0 DiTD (120KW,163PS) 4JJ1 Cylinder Head Assembly 8973559709 8982230192 908350 for Isuzu – OEM 8973559708

Product Overview: This complete cylinder head assembly is engineered for Isuzu 4JJ1 3.0-litre common-rail turbo-diesel engines, as fitted to the D-Max pickup and related commercial platforms. Supplied fully assembled with valves, guides and seats installed, it is a direct replacement for a cracked, warped or valve-damaged original head and is machined to original equipment tolerances.

Key Features: The casting is produced from premium-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, while the injector bores and glow plug threads are cut precisely to suit common-rail components. Reinforced casting around the fire deck and valve bridge improves durability at the high cylinder pressures typical of modern turbo-diesel engines.

Vehicle Compatibility: This head fits Isuzu D-Max I (January 2007 to June 2012), D-Max II (June 2012 to December 2018) and D-Max I platform and chassis cab models (2006-2012) equipped with the 4JJ1 engine. Always verify the engine code, casting marks and OE number against the original component before ordering.

Specifications: Engine code 4JJ1; displacement 3.0 litres; inline four-cylinder common-rail turbo-diesel; output rating approximately 120 kW / 163 PS in factory form; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; purpose replacement and repair.

OEM / Reference Numbers: 8973559708, 8973559709, 8987756067, 8982230192, 908350, 908351, 8-98217-4550, 8-98223-0801, 8-98238-3150, 8-98088-3714, 8-97355-9706, 8-97355-9707, 8-97355-9708, 8-97355-9709, 8-97945-0410, 8-98175-6060 and 8-98175-6061.

Applications: Suitable for pickups, light commercial vehicles and chassis cab conversions, covering fleet maintenance, workshop overhauls, engine rebuilds and off-road utility vehicle repairs where a robust factory-specification head is required.

Benefits / Replacement Information: This unit restores compression, corrects coolant and combustion leakage caused by cracking or gasket failure, and resolves overheating linked to head distortion. Buying a complete assembly avoids the cost and downtime of reconditioning the original valves, guides and seats.

Installation or Fitment Notes: Have the head installed by a qualified diesel technician. Check block deck flatness, fit new head bolts, gaskets and seals, and follow the manufacturer's torque sequence and angular stages. Replace timing and cooling system components as required, verify valve clearances and injector sealing, then run the engine to operating temperature and re-check for leaks before road testing.
