Shandong Yanzi Casting supplies cylinder heads specifically for the 6BT 5.9L diesel engine, commonly used in Dongfeng trucks and industrial machinery. The part is manufactured from ductile iron, a material chosen for its strength under high compression and thermal stress. It is designed as a direct replacement for OEM 3966454 parts and includes integrated exhaust manifolds and valve train mounting points.
Ductile iron grade QT450-10 is typical for heavy-duty diesel cylinder heads, offering tensile strength above 450 MPa and elongation of at least 10%. The casting process uses sand mold technology with controlled cooling to minimize internal defects. Surface finish on the combustion chamber and valve seats is machined to standard tolerances, though exact roughness values are not specified in the listing.
This cylinder head is primarily purchased by truck repair workshops, fleet operators in Africa, the Middle East, and South Asia, and distributors of Chinese-made diesel engine components. Packaging is wooden crate for single units and palletized bulk for orders over 100 pieces. Lead times range from 5 to 10 days depending on quantity, but exact MOQ and Incoterms must be confirmed directly with the supplier.

Shandong Yanzi Casting operates from Qihe County, Shandong Province, China, with a focus on casting components for diesel engines. The listing confirms production of 6BT 5.9L cylinder heads for truck applications but provides no details on founding year, workforce, production capacity, or export history. Its trust tier is harbor, indicating basic platform registration without third-party certification or audit claims.
The supplier does not mention ISO certification, in-house foundry capacity, or quality testing protocols. Response rate and average response time are not recorded, suggesting limited buyer interaction. Buyers should treat this as a casting specialist with defined product knowledge but unverified quality systems, and must request batch inspection reports and material certifications before placing orders.

Verify the cylinder head’s exact part number (3966454) and engine compatibility with your 6BT 5.9L diesel unit before ordering. Confirm that the combustion chamber type matches your engine’s injection system - this head is for indirect injection only. Request a material test report for QT450-10 and a flatness inspection certificate to ensure structural integrity.
Lead time varies from 5 to 10 days based on order size, but exact timelines must be confirmed. Incoterms are not listed; assume FOB Qingdao unless otherwise agreed. Payment is typically 30% advance, 70% against bill of lading. Ask whether the supplier provides export documentation, including commercial invoice, packing list, and certificate of origin.
Quality inspection should include checking valve seat hardness, combustion chamber dimensions, and coolant passage integrity. Request batch-specific X-ray or dye penetrant test reports. Ensure packaging is robust - wooden crates with internal bracing - to prevent damage during long-haul shipping. Inspect for cracks or porosity before accepting delivery.
