Resolve thermal fatigue in your 3.6L engine with our premium Mitsubishi 4D32 cylinder head (OEM: ME997277). This high-density cast iron head is engineered to prevent valve bridge cracking, providing a permanent solution for Fuso Canter FE305, FE325, and Rosa bus fleets. In stock for global wholesale dispatch.
The Mitsubishi 4D32 is a powerful 3.6L direct-injection diesel engine that has long been a staple of light-to-medium commercial transport. Powering the legendary Fuso Canter series and Rosa buses, this engine reflects Mitsubishi’s heritage of innovative engineering and reliable powertrains. However, the direct-injection (DI) design of the 4D32 generates significant heat concentrated at the cylinder head deck. In heavy urban logistics, this creates intense thermal cycles that lead to a common and costly pain point: fatigue cracking between the valve ports. These fractures result in compression loss, coolant consumption, and immediate vehicle downtime.
Ruich Value provides a definitive engineering fix for these high-stress environments. Our ME997277 cylinder heads are manufactured using high-density HT250-grade cast iron alloy, offering superior thermal stability and heat dissipation compared to standard aftermarket units. We have strategically reinforced the valve bridges to better handle the expansion and contraction cycles of the 3.6L DI engine. With a precision-machined deck flatness tolerance of ≤ 0.05 mm and mandatory 3MPa pressure testing, our heads ensure a perfect, permanent seal, keeping your commercial fleets operational and profitable.

The 4D32 is a direct-injection engine, meaning the heat of combustion is focused directly on the cylinder head deck. In heavy-duty logistics, the constant heating and cooling causes the narrow valve bridges to expand and contract excessively. This thermal fatigue eventually leads to fractures. Our heads are cast with reinforced valve bridges and high-density iron to dissipate this heat and stop the cracking cycle.
No, they are not interchangeable. The 4D30 is an indirect injection (IDI) engine with swirl chambers, while the 4D32 is a direct-injection (DI) engine with a flat deck. The injector port angles, combustion chamber design, and cooling passages are completely different. Always match the cylinder head to your specific engine code.
For the Mitsubishi 4D32, head bolts should be torqued in the factory sequence to 115-125 Nm (85-92 ft-lb). Since these bolts are subjected to high thermal stress, they often stretch beyond their elastic limit. We strongly recommend using brand-new head bolts to ensure proper clamping force and prevent head gasket failure.
We certify quality through a multi-stage process: first, magnetic particle inspection (MPI) to detect surface flaws, followed by a 3MPa pressure test using both air and water to ensure no internal porosity exists. Finally, the deck is precision-ground to meet strict flatness standards before the unit is sealed in rust-preventative packaging for global shipping.
