Product Description
C5336956 Cylinder Head is a critical cast assembly for DFCV ISB5.9 diesel engine. It carries intake valves, exhaust valves and fuel injectors, and integrates cooling water galleries and lubricating oil passages to shape the upper combustion chamber. This aftermarket replacement cylinder head resolves low cylinder compression, coolant cross leakage, power loss and white exhaust smoke caused by internal cracks, burnt fire deck and distorted sealing flange of aged cylinder heads. Reliable structural integrity stabilizes combustion process and cuts the risk of sudden breakdown for heavy trucks operating long-haul highway freight and heavy-load routes.
Product Advantages Manufactured from premium alloy cast iron with stress relief treatment to withstand cyclic high temperature and pressure. Precisely machined valve seats, injector bores and cooling channels deliver uniform heat dissipation. Smooth internal runners reduce flow resistance for air, coolant and lubricant. Each cylinder head passes hydraulic leakage test and flatness inspection before packing, OEM bolt hole layout and locating dimensions for direct fit during engine rebuild.
