Description
Overview:
The Pipe for Yanmar 4TNE Water Pump (MPN 129900 42070) is a genuine Yanmar coolant pipe that routes coolant to and from the water pump on 4TNE series diesel engines used in plant, construction and garden machinery. Built from robust, engineered metal with a corrosion‐resistant finish, it withstands heat, vibration and the harsh environments common on site and in the workshop. Its precise geometry maintains smooth coolant flow, helping to prevent hotspots and overheating and supporting reliable engine performance. As an OEM component, it matches the original dimensions and connection points for a clean, direct replacement on Yanmar 4TNE engines. This keeps downtime low and ensures consistent sealing with the existing pump and hose interfaces on equipment such as compact excavators, generators and industrial machinery.
Key Features:
- Genuine Yanmar part for assured compatibility and quality
- OEM dimensions and connections for a precise, direct fit on 4TNE engines
- Durable metal construction with corrosion‐resistant finish for long service life
- Engineered bends maintain efficient coolant flow and reduce restriction
- Resistant to heat, vibration and coolant chemistry in demanding duty cycles
- Helps protect against overheating by maintaining reliable coolant circulation
- Smooth mating surfaces support leak‐resistant joints with existing hoses and clamps
- Straightforward installation, reducing downtime during maintenance
- Suitable for construction, agricultural and garden machinery powered by Yanmar 4TNE
- Manufactured to Yanmar specifications for consistent performance
Typical Applications:
