Description
Overview:
This non-genuine water pump is a direct replacement for pumps used on Yanmar mini excavators. Built with a corrosion-resistant cast alloy body, metal internals and a sealed shaft, it circulates coolant through the engine and radiator to maintain stable operating temperature. It is suited to diesel engines in compact excavators, offering reliable flow for stop-start site work. The unit replaces Yanmar OEM numbers 119810-42002 and 119810-42003 and fits models such as B25V and VIO30 (see full compatibility below). A precision-machined mounting face and standard hose interfaces allow straightforward installation in place of a worn or leaking original pump. Keeping the cooling system in good order helps protect the cylinder head, gaskets and liners from heat stress, supporting dependable performance in daily use.
