What’s in the Box

  • 1 × Water Flush Plug Kit (17913-99E12)

Installation Notes

  1. Ensure the engine is turned off and has cooled down before starting.
  2. Locate and carefully remove the existing wash/flush plug from the engine cowling.
  3. Inspect the port threads for any dirt, damage, or old gasket material. Clean if necessary.
  4. Screw in the new water flush plug by hand until it is snug. Do not over-tighten.
  5. Connect a standard garden hose to the fitting on the new plug.
  6. Turn on the water supply fully. Check for leaks around the plug.
  7. Start the engine and run it only at idle speed for 5-10 minutes to flush the cooling system.
  8. Important: Always turn the engine OFF before turning the water supply OFF.
  9. Disconnect the garden hose. Depending on your engine, you may need to remove this plug and reinstall a standard plug before operation.

Troubleshooting & FAQ

Will this fit my Suzuki DF70A model?

No, this flush plug is specifically designed for non-A/B models. It will not fit DF60A, DF70A, or similar "A" and "B" designated engines. Please check your engine's full model number to confirm compatibility.

Is a gasket or o-ring required for installation?

This kit does not include a gasket. While some engine models may seal correctly without one, an o-ring or gasket is often recommended to prevent leaks. Please inspect and reuse your original gasket if it is in good condition or source one separately if needed.

What are the signs that I need to replace my flush plug?

Common failure signs include visible cracks in the plastic housing, stripped threads that prevent a secure connection, or water leaking from the plug area during flushing procedures. A damaged plug can lead to an ineffective flush and potential engine damage.

What is the correct way to use this flush plug?

Attach the plug to the engine's flush port, connect a garden hose, and turn the water on *before* starting the engine. Let the engine idle to circulate fresh water. To finish, turn the engine off *before* turning the water off. This prevents the engine from running dry.
