• Consistent Performance: Maintains stable heat output across multiple start cycles, reducing the risk of engine overheating or misfires.

Installation Guide

1. Safety First: Disconnect the battery to prevent accidental electrical discharge.
2. Locate the Glow Plug: Open the hood and identify the glow plug in the cylinder head. Refer to the vehicle’s service manual for exact positioning.
3. Remove Old Plug: Use a socket wrench with an extension bar to unscrew the old glow plug. Be careful not to damage the threads.
4. Inspect Cylinder Head: Check for any signs of wear or corrosion on the head surface. Clean if necessary.
5. Insert New Plug: Align the Vemo V99-14-0014 plug with the cylinder head and screw it in by hand until snug. Then tighten to the manufacturer’s torque specification (typically around 30 Nm).
6. Reconnect Battery: Reattach the battery terminals.
7. Test Start: Turn on the ignition and observe the glow plug indicator light (if present). The engine should start smoothly, even in cold conditions.

Maintenance Tips

• Check the glow plug indicator light during each engine start. A persistent “no glow” warning suggests a faulty plug.
• Inspect for visible cracks or damage after prolonged use, especially if the vehicle operates in extreme environments.
• Replace the glow plug every 30,000–50,000 km or as recommended by the manufacturer to maintain optimal performance.
