• Easy Installation: Designed with a universal mounting interface, mechanics can replace or upgrade the coil without extensive modifications.

Installation Guide

1. Disconnect Battery: For safety, remove the negative battery terminal before beginning work.
2. Remove Old Coil: Detach the spark plug wire from the existing coil and unscrew the mounting bolts. Carefully lift the old coil out of its housing.
3. Prepare New Coil: Inspect the U4001 for any visible damage. If necessary, clean the contact points with a non‑abrasive cleaner.
4. Mount the Coil: Position the new coil in the engine bay, aligning it with the mounting holes. Secure it using the supplied bolts and torque specifications (typically 10–12 Nm).
5. Reconnect Spark Plug Wire: Attach the spark plug wire to the high‑voltage terminal of the U4001.
6. Reattach Battery: Reconnect the negative battery terminal and start the engine. Verify smooth operation and absence of misfires.

Maintenance Tips

• Regularly inspect spark plug wires for wear or corrosion; replace them if they show signs of damage.
• Check the coil’s mounting bolts every 10,000 km to ensure proper torque and prevent loosening due to vibration.
• Avoid exposing the coil to excessive moisture or oil contamination; clean with a dry cloth if necessary.
• If experiencing persistent misfires after replacement, verify that all related ignition components (spark plugs, distributor cap, rotor) are in good condition.
