Glow Plug buying guide
Why replace this part?
Glow plugs pre-heat diesel combustion chambers to ensure reliable cold starting and clean combustion on startup. Worn glow plugs cause difficult cold-weather starting, white smoke on startup, and increased wear on starter motors.
Signs you need a replacement
- Difficult starting in cold weather
- white or blue smoke on cold start
- glow plug warning light staying on
- engine misfiring during warm-up
- increased starter motor cranking time
When to replace
Every 60,000–80,000 miles or when cold-starting problems develop. Replace all plugs as a set — a single failed plug causes uneven cylinder temperatures.
