The Hino N04C cylinder head (OEM: 11101-78210) is a 16-valve SOHC logistics-grade component cast from high-nickel alloy iron.
Designed for urban thermal cycles and high-pressure common rail injection, it fits Hino 300 Series (Dutro) and Toyota Dyna commercial fleets.
In stock for global export.
Urban logistics and Last Mile Delivery (LMD) operations demand exceptional durability from the 4.0L N04C diesel engine. Powering the Hino 300 Series (Dutro XZU) and the Toyota Dyna 400/500, this engine operates in a high-stress environment characterized by frequent start-stop cycles and intense thermal fluctuations. Our OEM-spec 11101-78210 cylinder head is specifically engineered as a logistics-grade solution, ensuring that your commercial transport or light truck maintains peak compression and cooling efficiency under the most demanding urban delivery schedules.
In high-traffic urban environments, the N04C engine often faces overheating issues related to the Exhaust Gas Recirculation (EGR) system and the high injection pressures of the common rail system. These conditions frequently lead to thermal cracking around the injector sleeves and valve bridges. Once micro-cracks develop, the engine suffers from combustion gas leakage into the cooling jacket, resulting in localized boiling, dashboard warning lights, and eventual engine seizure if left unaddressed. This common failure mode can paralyze delivery operations and result in significant lost revenue.
To combat these urban operational hazards, our 11101-78210 cylinder head is manufactured using an upgraded high-nickel grey cast iron alloy, providing superior resistance to thermal fatigue and localized hot spots. The deck surface is CNC-machined to a strict Ra 1.6 finish to guarantee a perfect seal with Multi-Layer Steel (MLS) gaskets, while the injector bores are reinforced to withstand modern fuel injection pulses. Featuring sintered steel valve seats and precision-cut guides, this head provides a heavy-duty platform for engine rebuilders seeking to restore original Euro 4/5 performance levels.

In Hino 300 and Toyota Dyna trucks, cracking around the injector bores is primarily caused by the extreme localized heat and high-pressure pulses of the common rail injection system. Urban stop-and-go driving exacerbates this by creating frequent thermal cycles. If the EGR system is not maintained, localized hot spots accelerate this fatigue. Our 11101-78210 head utilizes a logistics-grade alloy with higher nickel content to resist these thermal stresses better than standard aftermarket castings.
No, the N04C 4.0L engine utilizes a specific block architecture that is not interchangeable with the S05C or the 5.3L J05C platforms. While they may appear similar, the coolant passage alignment, head bolt patterns, and injector bore geometry are unique to the N04C family. Always verify your OEM part number (such as 11101-78210 or 11101-E0450) before initiating a rebuild.
To ensure a reliable seal with the multi-layer steel (MLS) head gasket, the N04C requires a precise spiral torque sequence. Tighten the head bolts in three stages: first to 59 Nm (44 ft·lb), followed by a 90-degree turn, and finishing with a final 90-degree turn. Since these are Torque-to-Yield (TTY) bolts, they must be discarded and replaced with brand-new hardware to maintain specified clamping force.
