Product Compatibility
Use only where the engine or heat-exchanger parts information specifies this plug thread and anode size. Confirm the engine model, serial number and available internal clearance before ordering.
Installation and Replacement
Inspect cooling-system anodes during scheduled service and replace depleted elements before protection is lost. With the engine cool and the water circuit safely isolated, follow the equipment manual for removal, thread preparation and leak checks. Keep the zinc element unpainted. View Martyr anode-care guidance.
Parts Desk Insight
The plug thread and the pencil dimensions are separate measurements. A plug that threads in correctly can still carry an anode that is too long for the heat exchanger.
