Without properly functioning glow plugs, diesel engines struggle or refuse to start in cold weather, produce excessive white smoke on startup, and may exhibit rough running until the engine reaches operating temperature.\u003c\/p\u003e\n\u003cp\u003eEach cylinder in a diesel engine has its own glow plug, and they typically wear out as a set. Modern glow plugs use an advanced ceramic or metal sheath element that reaches operating temperature within a few seconds of energizing the glow plug system — indicated by the glow plug light on your dashboard. When that light doesn't illuminate, or the engine cranks longer than usual before firing, suspect failing glow plugs.\u003c\/p\u003e\n\u003ch3\u003eSigns of Failing Glow Plugs\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHard starting in cold temperatures (below 40°F \/ 4°C)\u003c\/li\u003e\n  \u003cli\u003eWhite smoke from exhaust on startup that clears after warm-up\u003c\/li\u003e\n  \u003cli\u003eGlow plug warning light illuminated on dash\u003c\/li\u003e\n  \u003cli\u003eCheck engine light with glow plug circuit fault codes\u003c\/li\u003e\n  \u003cli\u003eRough idle and misfiring during engine warm-up\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eGlow plug replacement is often combined with a full diesel tune-up.
