Description
Overview:
This non-genuine Water Pump is a direct replacement for Yanmar part numbers 119540-42000 and 119540-42001, used on Yanmar 2TNV70 and 3TNV70 engines commonly fitted to compact excavators such as the Takeuchi TB016 and Hitachi ZX17U-2. It circulates coolant through the engine block and radiator to control operating temperature and prevent overheating under load. The pump features a robust cast alloy body with a durable hub to suit OE belt and pulley arrangements, making it suitable for demanding site conditions. Designed as a pattern part to match original mounting points and hose connections, it helps restore reliable cooling performance during routine maintenance or repair without modification.
Key Features:
- Non Genuine Part compatible with Yanmar 2TNV70 and 3TNV70 engines, replacing 119540-42000 / 119540-42001
- Hard-wearing cast alloy housing for strength and corrosion resistance in harsh environments
- OE-style hose outlets and bolt pattern for straightforward installation and correct alignment
- Stable coolant flow to protect the cylinder head, head gasket, and seals by preventing overheating
