Package Contents
- 4 x Heat Exchanger and Oil Cooler Zinc Anodes (Replaces Yanmar 119574-44150)
- 1 x Intercooler Zinc Anode (Replaces Yanmar 119574-18790)
- Note: Some Yanmar engines mated to a ZF transmission may require a fifth 119574-44150 anode for the transmission cooler. Please verify your specific configuration.
Installation Guide
- Shut down the engine and allow it to cool completely before starting work.
- Close the relevant seacocks to prevent water from entering the vessel.
- Locate the existing pencil anodes on the heat exchanger, oil cooler, and intercooler housings.
- Using the appropriate wrench (11/16" for the E-1F anodes), carefully unscrew the old anode plugs.
- Inspect the condition of the removed anodes. They must be replaced if they are 50% or more eroded.
- Clean the threads on the brass plug and inside the housing to ensure a good electrical connection and seal.
- Install the new zinc anodes, screwing them in until they are snug. Do not overtighten.
- Once all anodes are replaced, open the seacocks.
- Start the engine and carefully inspect for any leaks around the newly installed anode plugs.
Troubleshooting & FAQ
Q: How do I confirm this kit fits my Yanmar engine?
A: This kit is engineered for Yanmar's 4LHA, 6LP, and 6LY series engines (it does not fit the 6LY3 model). To ensure compatibility, please cross-reference your engine model with the "Compatible Engine Models" table on this page. This kit serves as a direct aftermarket replacement for OEM part number 119773-92600.
Q: How often should I replace these zinc anodes?
A: Regular inspection is key to engine health. We recommend checking your anodes every few months, and they should be replaced as soon as they show 50% erosion. This ensures your engine's cooling system components remain protected from galvanic corrosion.
Q: My engine setup seems to need an extra anode. Does this kit work?
A: Yes, this is a common configuration. Some Yanmar engines paired with a ZF transmission require an additional anode (our equivalent of Yanmar P/N 119574-44150) for the transmission cooler. This kit includes four of that specific anode. You may need to purchase one additional anode depending on your setup.
Q: What is the difference between the anodes included in this kit?
A: The kit contains two different anode types to service your engine. It includes four smaller anodes with 3/8" NPT threads for the heat exchanger and oil cooler, and one larger anode with a 1/2" NPT thread for the intercooler.
Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
