Step by step to change spark plugs in 2011 Chevy Impala?

Answer 1

To change the spark plugs in a 2011 Chevy Impala, first, ensure the engine is cool and disconnect the negative battery cable. Remove the engine cover if necessary, then carefully pull off the ignition coil connectors and unscrew the coils to access the spark plugs. Use a spark plug socket and ratchet to remove the old plugs, applying anti-seize compound to the threads of the new plugs before installing them. Finally, reassemble the ignition coils, reconnect the battery, and start the engine to ensure everything is functioning properly.
