How to Replace Spark Plugs in a Honda CR-V


The Honda CR-V manual indicates that spark plugs need to be replaced every 100,000 miles. Clean and efficient spark plugs allow the Honda CR-V engine to use less gas and run more efficiently. Replacing Honda CR-V spark plugs takes approximately 1 hour to complete once the engine is cool. Never work on an aluminum engine while it is still warm.

Things You'll Need

  • Spark plug socket
  • Socket wrench with extension
  • Anti-seize compound
  • New spark plugs
  • Tension testing tool
  • Trim panel removal tool
  • Locate the spark plug cables along the top or the sides of the engine, depending on CR-V model. Once the engine cools, use the trim panel tool to twist the spark plug wire at the wire's boot, which is the larger rubber portion located on top of the spark plug.

  • Pull back on the spark plug wire to remove it from the spark plug.

  • Place the socket on top of the spark plug and turn it counter-clockwise to unscrew and remove the spark plug from the well.

  • Rub anti-seize lubricant onto the new spark plug threads and on the tip of the spark plug.

  • Insert the new spark plug into the well. Manually turn the plug clockwise to thread the spark plug into place.

  • Test the tension on the plug with the tension testing tool. Adjust the tension as needed. Honda CR-V spark plugs generally need a tension between 10 and 15 foot pounds. The spark plug's packaging indicates its suggested tension.

  • Replace the spark plug wire, turn it from side to side and lock it into place. Continue the process with the rest of the spark plugs one at a time until all of the spark plugs are replaced.
