5. Instal·lació

Proper installation is crucial for the optimal performance and longevity of the DENSO DG-001 Glow Plug. If you are unsure about any step, consult a qualified mechanic.

5.1 Comprovacions prèvies a la instal·lació

1. Confirm the new glow plug matches the specifications of the original part for your vehicle.
2. Inspect the new glow plug for any visible damage.
3. Ensure the engine is completely cool to prevent damage to cylinder head threads.

5.2 Procediment d'instal·lació

1. Locate the glow plugs on your engine. They are typically found on the cylinder head.
2. Carefully disconnect the electrical connector from the top of the old glow plug.
3. Using an appropriate glow plug wrench, slowly loosen and remove the old glow plug. Exercise caution to avoid breaking the plug in the cylinder head.
4. Clean the glow plug bore in the cylinder head to remove any carbon deposits.
5. Gently thread the new DENSO DG-001 Glow Plug into the cylinder head by hand to ensure it starts correctly and avoids cross-threading.
6. Using a torque wrench, tighten the glow plug to the specified torque of 15 - 20 Nm. Overtightening can damage the glow plug or cylinder head threads.
7. Reconnect the electrical connector to the new glow plug.
8. Repeat the process for any other glow plugs being replaced.

6. Funcionament

Glow plugs are essential components in diesel engines, primarily assisting with cold starting. When the ignition is switched on, the glow plug's heating element rapidly heats up, creating a hot spot in the combustion chamber. This heat helps to ignite the atomized diesel fuel, especially when the engine block is cold and compression alone is insufficient to raise the air temperature high enough for combustion. The DENSO DG-001 is designed for fast heat-up times and extended post-heat temperatures to ensure efficient combustion and reduced emissions during the engine's warm-up phase.

7. Manteniment

Glow plugs are wear items and their performance can degrade over time. While the DENSO DG-001 is built for durability, regular inspection and timely replacement are recommended to maintain optimal engine performance.

• Inspecció: Periodically check the glow plugs for signs of damage, carbon buildup, or corrosion on the terminals.
• Interval de substitució: Refer to your vehicle manufacturer's service schedule for recommended glow plug replacement intervals. It is generally advisable to replace all glow plugs at the same time to ensure balanced performance.
• Servei professional: If you suspect a glow plug issue or are unsure about replacement, consult a professional mechanic.

8. Solució De Problemes

Common symptoms of faulty glow plugs include:

• Dificultat d'inici: Especially noticeable in cold weather, the engine may crank for an extended period before starting or may not start at all.
• Ralentí irregular: The engine may run unevenly or roughly immediately after starting.
• Increased Smoke: White or blue smoke from the exhaust during cold starts can indicate unburnt fuel due to insufficient heat.
• Llum de revisió del motor: Some modern vehicles may illuminate the check engine light or glow plug warning light if a fault is detected.

If you experience any of these symptoms, it is recommended to have the glow plugs tested by a qualified technician.
