Weichai BY612600190629 Turbocharger Coolant Pipe Assembly

The BY612600190629 turbocharger coolant outlet pipe is engineered for Weichai heavy-duty diesel engine platforms. It channels high-temperature coolant from the turbocharger bearing housing back to the engine cooling circuit, maintaining thermal stability of the turbine shaft assembly. Manufactured from high-grade carbon steel with corrosion-resistant surface treatment, the pipe features precision-formed flanges and beaded hose connection ends to ensure secure sealing under cyclic thermal expansion and vibration loads. The internal bore geometry is optimized for minimal flow restriction, supporting efficient heat rejection from the turbocharger center housing rotating assembly (CHRA). This component serves as a direct replacement for the OEM Weichai part number BY612600190629, compatible with WP10, WP12, and WP13 engine series commonly deployed in Shacman, Sinotruk Howo, and FAW Jiefang heavy trucks, as well as construction machinery including loaders and excavators.
