Nissan 22162-21P01PU Cap Assembly

Removal steps 1. Park the vehicle on level ground, set the parking brake, let the engine cool, and wear eye protection and gloves. 2. Disconnect the negative battery cable and keep the terminal clear of any metal surfaces. 3. Identify the distributor cap area - the exact location and orientation vary by engine design. 4. Remove any engine covers or other components that obstruct access, if necessary. 5. Label each spark plug wire and note their positions on the cap so they can be reinstalled in the same order. 6. Remove spark plug wires by pulling the boot (not the wire); use a twisting motion if they are tight. 7. Remove the cap retaining hardware (clips, screws, or clamps) and keep those fasteners organized. 8. Lift the distributor cap straight off; if it resists, gently work it free without forcing or levering on internal parts. 9. Inspect the rotor and cap mating surfaces for wear, corrosion, or carbon tracking; remove the rotor only if replacement is required and the removal method varies by design. 10. Clean debris from the distributor opening and surrounding area before installing the new cap. Installation steps 1. Verify the replacement cap matches the original in terminal arrangement and overall fit. 2. Install a new rotor if needed, seating it fully in the correct orientation (installation method varies by design). 3. Position the new distributor cap onto the distributor, aligning any locating features noted during removal, and do not force it. 4. Reinstall and snug the cap retaining hardware evenly; avoid overtightening. 5. Reconnect spark plug wires to the terminals in the exact order you labeled, pressing each boot firmly onto its contact. 6. Apply a small amount of dielectric grease inside each boot to help seal and prevent corrosion (repair tip). 7. Reinstall any removed engine covers or components. 8. Reconnect the negative battery cable. 9. Start the engine and listen for a smooth idle; if you hear misfires, arcing, or rough running, shut the engine off and recheck wire order and connections. 10. Confirm all fasteners are secure and no tools or debris remain in the engine bay.
