Nissan Navara Glow Plugs Malaysia — NP300 YD25 Diesel
Navara NP300 is a diesel engine — it uses glow plugs, not spark plugs. Glow plugs preheat the combustion chamber for cold starts. Faulty glow plugs cause hard starting, white smoke on startup, and rough running in cold conditions. Inspect at 80,000 km, replace as needed. A failed glow plug relay will also prevent starting.
