Looking for a replacement Nissan YD25 cylinder head (OEM: 11040-EC00C)? This high-performance alloy unit fits Navara D40 and Pathfinder R51 engines. It is engineered with reinforced cooling galleries to eliminate the cracking and warping common in heavy-duty diesel applications. Ready for B2B wholesale export.
The Nissan YD25DDTi engine is the core power unit for the Navara D40 and Pathfinder R51, but it is well-known in the repair industry for its sensitivity to thermal stress. For fleet operators and individual owners, the sudden appearance of bubbles in the expansion tank or a localized overheat often signals a cracked or warped cylinder head. This 11040-EC00C cylinder head is designed specifically to restore the integrity of the YD25’s high-pressure combustion chamber.
Unlike standard aftermarket castings, Ruich Value’s YD25 cylinder head utilizes an advanced gravity-casting process with premium aluminum alloys that offer superior thermal conductivity. We have reinforced the structural bridges between the valve seats—the most common failure point—to ensure our heads can withstand the high Exhaust Gas Temperatures (EGTs) produced during heavy towing or off-road use. This unit ensures a perfect seal and long-term reliability for your 2.5L common-rail diesel engine.

The primary cause is localized boiling within the cylinder head. The YD25 engine has very narrow cooling passages. If the cooling system is not perfectly maintained (e.g., old coolant or air pockets), the metal between the valve seats overheats and develops stress cracks, leading to internal coolant leaks and loss of compression.
No. The 11040-EC00C is specifically designed for the common-rail YD25 Euro 4 engines. The intake ports and sensor mounting points differ significantly from earlier models. Always check your engine code and VIN to ensure you are purchasing the “Common Rail” version of the cylinder head.
Absolutely. The YD25 head bolts are “Torque-to-Yield” (stretch) bolts. Once they have been tightened to their final angle, they are permanently deformed. Reusing old bolts will not provide sufficient clamping force, which will almost certainly cause the head gasket to blow within a few hundred kilometers of operation.
Gasket thickness is determined by piston protrusion, not the head itself. Because our 11040-EC00C is a new casting with a standard deck height, you must measure how far the pistons rise above the block and select the corresponding grade (1, 2, or 3 holes) of the gasket as specified in the service manual.
Yes. If you are purchasing a “bare” head, you will be transferring your valves and shims. Since the valve seats in the new head are fresh, the installed height of your valves will change. You must perform a full valve clearance check (shim adjustment) during assembly to prevent valve burnout or poor idle performance.
