Yanmar 119574-44150 is a genuine OEM zinc engine anode used in Yanmar marine diesel cooling-system applications. It is commonly described as a small oil cooler and heat exchanger zinc anode, used to help protect internal raw-water side components from galvanic corrosion in saltwater service. Public listings consistently describe it as a screw-in pencil-style anode.
Key Features
- Genuine Yanmar OEM zinc anode
- Pencil-style screw-in engine anode
- Commonly listed for oil cooler and heat exchanger use
- Typical published specs: 3/8" NPT thread, 1-1/4" overall length, 1/2" diameter, 11/16" wrench size
- Intended for saltwater corrosion protection inside raw-water cooled components.
Engine Compatibility
Commonly listed for these Yanmar marine diesel applications:
- 4LHA series: 4LHA-HTE, 4LHA-HTP, 4LHA-DTE, 4LHA-STE, 4LHA-DTZE, 4LHA-STZE, 4LHA-DTP, 4LHA-STP, 4LHA-DTZP, 4LHA-STZP
- 6LP series: 6LP-DTE, 6LP-DTZE, 6LP-STE, 6LP-STZE, 6LPA-DTP, 6LPA-DTZP, 6LPA-STP, 6LPA-STZP
- Some sellers also list fitment across 6LY applications, while others reference certain 4LV fuel-cooler and 6LY applications separately. Because listings vary, fitment should be confirmed by engine model, serial number, installed cooler location, and anode dimensions before ordering.
Serial Number Fitment Notice
Fitment should be confirmed by engine model and serial number, plus the installed cooling component, before ordering. This part is used in multiple Yanmar families, and public fitment lists are not fully identical across sources.
When This Part Needs Replacement
Replace when the zinc is heavily wasted, reduced in diameter, brittle, scaled, or no longer providing usable sacrificial mass. Engine anodes should be inspected regularly because they protect internal cooling passages, oil coolers, and heat exchangers where corrosion damage can become expensive if service is delayed.
Installation Notes
Install only where a 3/8" NPT zinc anode of this size is specified. Confirm thread type, diameter, and installed length before installation. Clean the threads and sealing area, and verify the replacement matches the removed anode exactly. Some aftermarket listings also offer this part as a refill or as a complete anode with plug, so confirm whether the application needs the anode only or the complete assembly.
Alternate / Superseded Part Numbers
- 119574-44150
- Common aftermarket cross-reference: E-1F
- Some replacements are sold as equivalent refill-only or complete anode versions rather than a Yanmar-numbered supersession.
Parts Desk Insight
This is one of those Yanmar anodes where the part number is the safest match point. Public sources broadly agree on the size and general 4LHA/6LP use, but they do not all agree on every engine family listed. Matching by Yanmar part number, engine serial number, and the installed cooler location is the most reliable way to avoid ordering the wrong anode.
