How to Replace Spark Plug Wires on a Chevy Beretta

Spark plug wires on your Chevy Beretta should be replaced every 30,000 miles. The plug wires are responsible for delivering the spark to the engine cylinders from the power distributor. This is a crucial electrical component. If the wires are not functioning normally, you will not get a sufficient spark to ignite the plugs and create the combustion necessary for the engine to run. You can get new spark plug wires at any auto parts store. You should work on only one plug at a time.

Things You'll Need

• New spark plug wires

Instructions

1. Open the hood of your Beretta and locate the spark plug wires running across the top of the engine.

2. Grab one of the plug wires (it doesn't matter which one you start with) at the plug, and wiggle the plug back and forth while you pull up on it. It should come right out of the top of the engine.

3. Follow the plug wire to the distributor, and pull the plug off the distributor in the same manner that you removed it from the top of the engine.

4. Plug the new wire of the same length as the old plug wire onto the engine and distributor. Fit the small plug end of the wire over the distributor electrode, and push it into place to secure it to the distributor. Then insert the large end of the plug wire down into the engine spark plug well, and press it over the top of the spark plug.
