- Gloves to protect your hands
2. Prepare the Engine
- Allow the engine to cool down completely.
- Disconnect the negative terminal from the battery.
3. Remove the Ignition Coils
- Locate the ignition coils on top of the engine. They are usually cylindrical and have spark plug wires connected to them.
- Disconnect the spark plug wires from the ignition coils.
- Use a ratchet and the appropriate socket to loosen and remove the bolts holding the ignition coils in place.
- Carefully lift the ignition coils off the spark plugs.
4. Remove the Spark Plugs
- Use the spark plug wrench or socket to loosen and remove the spark plugs.
Be careful not to drop them into the engine compartment.
5. Check and Gap the Spark Plugs (if needed)
- Inspect the old spark plugs for signs of wear, fouling, or damage.
- If the new spark plugs are not pre-gapped, use a gapping tool to adjust the electrode gap to the manufacturer's specifications.
6. Install the New Spark Plugs
- Thread the new spark plugs into the cylinder head by hand until they are snug.
- Use the spark plug wrench or socket to tighten the spark plugs until they are firmly seated.
- Be careful not to overtighten the spark plugs, as this can damage the threads.
7. Reinstall the Ignition Coils
- Place the ignition coils back over the spark plugs.
- Secure them using the bolts you removed earlier.
- Re-connect the spark plug wires to the ignition coils.
8. Reconnect the Battery
- Reconnect the negative terminal to the battery.
9. Start the Engine
- Start the engine and let it run for a few minutes.
- Listen for any unusual noises or check for any warning lights on the dashboard.
By following these steps, you should have successfully changed the spark plugs on your 1995 Acura Legend. Remember, if you are not comfortable performing this task or have any doubts, it's best to consult a qualified mechanic.
