Product Description
C3900955 Engine Block Core Plug is a press-fit sealing plug installed on cylinder block water jacket of DFCV ISB diesel engine. It covers the casting holes of cooling gallery, keeps coolant inside the circulation channel and serves as a buffer to prevent cylinder block cracking when coolant freezes and expands. This aftermarket replacement core plug resolves slow coolant dripping, continuous liquid loss and recurring engine overheating caused by rust perforation, plug popping out and surface corrosion of old plugs. Stable sealing maintains normal cooling circulation and protects the power unit for heavy trucks running long-haul highway freight and low-temperature region transport tasks.
Product Advantages Made of anti-corrosion carbon steel with rust-proof surface treatment. Dish-shaped structure is designed for uniform pressure bearing. Accurate size realizes reliable interference fit after pressing and avoids falling off under water pressure. Each core plug passes dimension inspection and appearance screening before packing, OEM specification for press installation in engine overhaul.
