Technical Specifications

Installation Guide

1. Preparation: Ensure the engine is cool and disconnect the battery to prevent accidental electrical discharge.
2. Removal of Old Plug: Use a socket wrench with an extension bar to unscrew the existing glow plug. Keep track of any retaining rings or seals.
3. Cleaning: Clean the cylinder head area with compressed air and remove any debris that may interfere with seating.
4. Insertion: Align the new Metzger H1 860 plug with the threaded hole. Hand‑tighten first to avoid cross‑threading, then use a torque wrench set to the manufacturer’s recommended value (typically around 30–35 Nm).
5. Verification: Check that the plug is fully seated and that no gaps remain between the plug tip and cylinder head.
6. Reconnection: Reconnect the battery and perform a test start to confirm proper operation.

Maintenance Tips

• Inspect glow plugs periodically for signs of wear or corrosion, especially if the vehicle is used in harsh environments.
• Avoid using excessive torque during installation; over‑tightening can damage threads and reduce heat transfer efficiency.
• If the engine struggles to start after a cold night, consider replacing the glow plugs as they may have degraded.
