Gain access to the spark plugs and spark plug wires. In a 2.4 liter engine, remove the ignition coil and module assembly from the top of the engine to gain access. In this Alero model's engine, the spark plugs run down the center of the engine. In a 3.1 liter engine, remove the air cleaner to gain access. The spark plugs are located next to the engine oil reservoir. For a 3.4 liter engine, remove the windshield wiper module cover and rotate the engine for service access. For a 2.2 liter engine, the spark plug wires are located across the top of the engine and require no components to be removed for access to the spark plugs.
