Beru AG 0100221101 Glow Plug

Beru AG 0100221101 Glow Plug: Precision Engineered for Diesel Performance

The Beru AG 0100221101 Glow Plug is a high‑quality ignition component designed to deliver reliable combustion in diesel engines. Crafted with advanced materials and meticulous engineering, this glow plug ensures consistent start-up even under the most demanding conditions.

Key Technical Specifications

• Model: AG 0100221101 (also listed as GV112 in various catalogs)
• Type: Stabglühkerze (stainless steel filament) for optimal heat retention
• Voltage: 12 V DC, compatible with standard automotive electrical systems
• Current Rating: 6 A – sufficient to achieve rapid ignition without excessive power draw
• Thread Size: M10 × 1.0 mm – a common fit for many European diesel engines
• Length: Approximately 90 mm, matching the standard bore dimensions of target vehicles

Design Features That Set It Apart

The glow plug incorporates a robust ceramic insulator that protects the filament from corrosive engine gases while maintaining excellent thermal conductivity. The stainless steel housing resists high temperatures and mechanical stress, ensuring longevity even in engines with frequent cold starts.

A precision‑machined tip guarantees uniform heat distribution across the combustion chamber, reducing the risk of misfires or uneven wear on piston rings. This design is particularly beneficial for older models where engine tolerances may have degraded over time.

Compatibility and Application Range

This glow plug is engineered to fit a wide array of diesel engines, notably:

• Morris Marina II Stufenheck – the original application for which the GV112 was developed
• Various BorgWarner and Beru branded diesel engines that share the M10 × 1.0 thread standard
• Other European diesel vehicles requiring a 12 V, 6 A glow plug with a 90 mm length

Because of its universal thread size and voltage rating, mechanics often use the AG 0100221101 as a drop‑in replacement for older or worn glow plugs in both passenger cars and light commercial vehicles.

Installation Guidance

1. Safety First: Ensure the engine is completely cool before handling any ignition components.
2. Remove Old Plug: Use a suitable socket (typically 17 mm) to unscrew the existing glow plug. Inspect the bore for damage or excessive wear.
3. Insert New Plug: Align the M10 thread and gently screw in, avoiding cross‑threading. Tighten to manufacturer specifications.
4. Check Electrical Connections: Verify that the wiring harness is intact and properly connected to the glow plug’s terminal.
5. Test Start-Up: After installation, attempt a cold start. The engine should ignite smoothly within seconds, indicating correct operation.

Maintenance Tips for Longevity

• Regularly inspect the glow plug for signs of corrosion or cracking; replace if any damage is observed.
• Avoid exposing the plug to extreme temperatures outside its rated range, as this can degrade the ceramic insulator.
• Use a high‑quality diesel fuel additive to reduce particulate buildup that may affect heat transfer.
