J08C 1989-2004 - 11101-E0541 11101-E0530 11101-E0531 Cylinder Head for Hino Truck J08C J08E Engine – OEM 11101-E0541

Product Overview: This complete cylinder head assembly is a direct-fit replacement for J08C, J08E engines, supplied fully assembled and ready to install. It replaces the original casting on Hino applications and restores correct combustion chamber geometry, valve sealing and gas flow without additional machining. Each unit is pressure tested before packing and carries a 12-month warranty. It is intended for replace/repair use and is a cost-effective alternative to reconditioning a damaged original head. The unit is inspected for flatness and gallery cleanliness prior to dispatch, ensuring it is ready for immediate fitment.

Key Features: The head is CNC-machined from high-grade aluminium alloy or cast iron to deliver consistent deck flatness, accurate valve seat concentricity and correctly sized ports. Valve guides and seats are pre-installed and finish-honed, and combustion chamber volumes are matched cylinder to cylinder for balanced compression and a stable idle. Reinforced casting walls around the valve bridge and injector or plug bosses improve thermal durability, while the machined cam carrier maintains correct bearing clearance. All internal oil and coolant galleries are cleaned, inspected and flow-checked before the head is assembled and tested. The casting is dimensionally stable and accepts original-specification gaskets, bolts and ancillary components.

Vehicle Compatibility: This assembly fits J08C 1989-2004. Always confirm the engine code and reference number against the original component before ordering, as several variants and market build codes use visually similar heads. Coverage spans the 1989-2004 model years.

Specifications: Engine code / family: J08C, J08E; Material: high-grade aluminium alloy or cast iron; Size: STD; Condition: New, supplied for replace/repair use; Warranty: 12 Months; Packaging: neutral export carton.

OEM / Reference Numbers: Primary reference numbers for this head include 11101-E0541, 11101-E0530, 11101-E0531, WG1143040. Cross-reference these with the casting marks and engine code on the original cylinder head to confirm the correct variant.

Applications: Suitable for passenger cars, light commercials and utility vehicles built on Hino platforms, covering workshop repairs, engine overhauls and fleet maintenance where a factory-specification casting is required.

Benefits / Replacement Information: Fitting this complete assembly restores lost compression, eliminates coolant loss and combustion gas transfer caused by a failed head or gasket, and removes the cost of separately reconditioning valves, guides and seats. Because the unit arrives assembled and tested, downtime and labour are reduced compared with repairing an original casting.

Installation or Fitment Notes: Before fitting, clean and inspect the block deck and bolt threads, check the head for flatness and confirm the gasket, bolt set and torque sequence specified for the engine. Fit new head bolts where stretch bolts are used, follow the tightening stages and angles precisely, and refill with the correct coolant. Run the engine to temperature, then re-check coolant level and re-torque if required.
