To inspect and replace the spark plugs on your Pro XD Mid-Size Gas, follow these steps:
1. Park the vehicle on a flat level surface and ensure it is in PARK.
2. Pull up on the cargo box latch and pivot the box up.
3. Wipe away any dirt or debris around the spark plug boot with a clean, dry cloth.
4. Carefully remove the spark plug boot.
5. Carefully loosen the spark plug with a 5/8-inch spark plug socket and remove from the vehicle.
6. Inspect the electrode for wear and carbon buildup and verify there are no cracks around the insulation. The spark plug should have a sharp outer edge with no rounding or erosion.
7. Inspect and adjust the spark plug gap if needed. It should measure 0.7-0.8mm.
8. If necessary, replace with the recommended spark plug. Severe engine damage may occur if the incorrect plug is used. New spark plugs are part number 3022662.
9. Install the spark plug into the engine, and torque to 9 ft-lbs (12 Nm). Do not apply anti-seize to the threads.
10. Apply a small amount of dielectric grease to the spark plug boot.
11. Reinstall the spark plug boot and ensure it is fully seated.
12. Tilt the cargo box down and ensure it is properly latched.
13. Start the engine in a well-ventilated area to verify proper operation.
