It protects the vital, more expensive metal parts of your engine's cooling system (like the heat exchanger, aftercooler, and oil cooler) from galvanic corrosion by corroding first.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow often should I inspect and replace these anodes?\u003c\/summary\u003e\u003cp\u003eAnodes should be inspected as part of your regular engine maintenance schedule, typically every few hundred hours or at least annually.

If the anode is gone, your engine's internal components are actively corroding and unprotected.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eMy engine setup seems to have five anodes, but this kit only contains four of the smaller ones. Why?\u003c\/summary\u003e\u003cp\u003eThe standard Yanmar engine configuration requires the four E-1F anodes and one E-2 anode included in this kit. However, some Yanmar engines are paired with a ZF transmission that has its own, separate pencil anode. That fifth anode for the transmission is not part of this engine kit and must be purchased separately.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the difference between the anode types in this kit?\u003c\/summary\u003e\u003cp\u003eThis kit contains two types of anodes to fit different components.
