Honda GCV160 Spark Plug: Essential Guide for Maintenance and Replacement

If you have a small engine like the Honda GCV 160, knowing how to replace the spark plug is an essential skill. In this guide, we’ll walk you through the process of replacing the spark plug on a pressure washer powered by a Honda GCV 160 engine.

The spark plug you choose should be suitable for your specific application. For our pressure washer, we used the NGK VPR 60S spark plug. It’s crucial to select the right spark plug for optimal engine performance.

To begin the replacement, disconnect the spark plug connector and carefully remove the old spark plug. Inspect the old spark plug for any signs of damage, fouling, or wear. This step is important to assess the engine’s condition.

Compare the old spark plug with the new one to ensure they are the same type. In our case, the new spark plug is also the BPR 60S. Checking the compatibility is essential before proceeding with the installation.

Prior to installing the new spark plug, check the electrode gap. It should fall within the range of 0.028 to 0.030 inches. Use a gapping tool to adjust the gap if necessary. Once the gap is correct, you can proceed with installing the new spark plug.

When screwing in the new spark plug, take care not to cross-thread it. Hand tighten it first, then use a wrench to give it a final half turn. Avoid over-tightening, as this can lead to damage.

Finally, reconnect the spark plug connector to ensure proper engine function. Once everything is securely in place, you can start the engine and test the new spark plug.

By following these steps, you can ensure that your small engine runs smoothly with a new spark plug, promoting optimal performance and longevity.

Where is the spark plug located on the Honda GCV 160 engine?

The spark plug is located at the back of the pressure washer, with a spark plug connector.

What type of spark plug is recommended for a pressure washer and other applications?

For a pressure washer and other applications, the recommended spark plug is the NGK VPR 60S. For other applications, the BP RV should be used.

How do I replace the spark plug?

To replace the spark plug, first remove the spark plug connector, then inspect and remove the old spark plug. Check the type and gap of the new spark plug before installation. Carefully screw in the new spark plug, ensuring it’s not cross-threaded, and tighten it as recommended. Finally, don’t forget to plug in the connector before starting the engine.
