The Hino J05CT cylinder head (OEM: 11101-3720) is a reinforced casting designed specifically for the 5.3L turbocharged diesel engine.
Engineered with high-grade exhaust valve seats to withstand severe thermal loads, it fits Hino Ranger FC/FD and Dutro commercial trucks.
In stock for global export.
The Hino Ranger and high-output Dutro platforms rely on the turbocharged 5.3L J05CT diesel engine to deliver maximum payload capacity across demanding commercial routes. Unlike its naturally aspirated counterparts, the J05CT generates significantly higher cylinder pressures and exhaust temperatures. When these engines suffer from severe overheating or high-mileage fatigue, replacing the damaged top end with an exact-spec 11101-3720 cylinder head is the only way to fully restore factory compression and prevent ongoing power loss in your commercial fleet.
In turbocharged applications, the cylinder head is the primary victim of thermal shock. Immediate engine shutdowns after heavy highway hauling stop coolant circulation while the turbo is still radiating extreme heat (often exceeding 700°C). Over time, this thermal stress causes micro-fractures to propagate between the valve bridges and injector bores. Once these cracks breach the cooling jacket, combustion pressure pushes coolant out of the overflow, leading to rapid overheating, milky oil, and a total loss of pulling power.
To combat the intense operating environment of the J05CT, our 11101-3720 cylinder head is manufactured from an advanced, alloyed grey cast iron that resists thermal fatigue. We incorporate enlarged, high-flow water jackets to rapidly dissipate turbocharger-induced heat spikes. Every cylinder deck is CNC-milled to an exacting Ra 1.6 surface finish, ensuring maximum retention for multi-layer steel (MLS) head gaskets. By utilizing pre-installed, high-grade sintered exhaust valve seats, engine rebuilders can guarantee a permanent repair that withstands the rigors of heavy freight hauling.

Cracking between the valve bridges in the turbocharged J05CT engine is primarily caused by thermal shock. When heavily loaded commercial trucks are shut down immediately after highway driving, the turbocharger heat soaks the top end while coolant circulation is stopped. Over time, this extreme temperature variance fractures the cast iron between the exhaust valves. Our 11101-3720 cylinder head features reinforced webbing and upgraded metallurgy to resist this localized thermal stress.
No, using a naturally aspirated (NA) cylinder head on the turbocharged J05CT platform will result in rapid failure. The 11101-3720 turbo-spec head utilizes different casting core designs with enlarged water jackets to handle significantly higher exhaust temperatures. Additionally, it features upgraded exhaust valve seats that resist the severe erosion caused by forced induction. Always verify cross-reference numbers like 11101-E0130 for turbo applications.
To prevent deck warpage, the head bolts must be tightened in a precise spiral sequence starting from the center. The J05CT requires a three-step Torque-to-Yield (TTY) procedure: Step 1 tightens bolts to 59 Nm (44 ft·lb), Step 2 is a 90-degree turn, and Step 3 is a final 90-degree turn. Because these bolts permanently stretch under tension, you must discard the old bolts and install new OEM-spec hardware.
