Tools needed to replace spark plugs
1. Deep nozzle; 2. Torque wrench; 3. Ratchet wrench; 4. Extension cord; 5. Wire gauge for checking spark plug gaps
1. Inspect new spark plugs for cracks or damage.
2. Using a wire gauge, check the spark gap.
3. If necessary, adjust the gap by bending the side electrode.
4. On six-cylinder engines, remove the bolt (A), disconnect the wire (B) and remove the ignition coil to gain access to the spark plug.
5. Disconnect the wires from the spark plugs.
6. Use compressed air to clean the area around the spark plugs and remove the spark plugs using a deep socket and extension.
7. Before installing new spark plugs, coat their threads with an anti-corrosion compound. Screw the plugs into place, using a piece of rubber hose as a universal joint to avoid damaging the threads. Tighten the plugs to the specified torque.
