Forklift Water Pump – Yunnei 4100 490 Diesel Engine

Forklift Water Pump — Yunnei 4100 / 490 Diesel Engine Cooling Water Pump for Multi-Brand Forklift Applications

This forklift water pump is a Kingstream OEM engine cooling water pump for Yunnei 4100 and 490 diesel engines used in forklift trucks from multiple brands including Weichai, Xinchai, Laidong, Quanchai, Chaochai, Yangchai, Changchai, Yuchai, and Dong Fang Hong — covering the 4100, 4100QB, 495, 490, 498, and related engine families. The water pump is compatible with construction machinery from Liugong, Foton Lovol, SDLG, Sunward, Shantui, Xiagong, and Beilong — plus trucks from Foton, JAC, Dongfeng, CNHTC-SINO, FAWDE, Yuejin, and Shacman, and buses from Yutong, Higer, Zhongtong, Kinglong, and Huanghai. 8kg with color box packaging. ISO9001:2008 certified with 3-month warranty. Hebei, China origin.

Installing the Yunnei 4100/490 water pump requires draining the engine coolant, removing the fan belt, unbolting the old pump from the engine block, thoroughly cleaning the mounting surface of old gasket material and corrosion, installing a new gasket, and torquing the mounting bolts to specification in a cross pattern. The Yunnei 4100 and 490 engines share the same basic architecture across multiple equipment brands — forklifts, construction machinery, trucks, and buses — making this water pump a widely applicable replacement part for fleet operators managing mixed equipment. At 8kg, two-person handling is recommended during installation. After installation, refill coolant, bleed air from the cooling system, and verify no leaks at the mounting surface or weep hole. For multi-brand fleets using Yunnei-powered forklifts alongside construction machinery, standardizing on this water pump reduces parts inventory complexity. 3-month warranty and ISO9001:2008 certification.
