Product Description
C3905401 Engine Block Core Plug is a pressed sealing plug mounted on DFCV ISD6.7 diesel engine cylinder block. It seals the casting process holes of water jacket, prevents coolant leakage and protects the cylinder block from frost cracking when coolant freezes and expands. This aftermarket replacement core plug fixes slow coolant seepage, fluid loss and engine overheating caused by plug corrosion, loosening and surface rust perforation of aged plugs. Reliable sealing maintains stable cooling circuit pressure and reduces engine damage risk for heavy trucks running long-distance highway transport and low-temperature area delivery missions.
Product Advantages Made of high-quality carbon steel with anti-corrosion surface treatment. Precision outer diameter design ensures tight interference press fit into block hole. The curved dish structure bears internal water pressure steadily without easy pop-out. Each core plug undergoes dimension inspection and anti-rust screening before packing, OEM specification for press installation during engine cooling system overhaul.
