Tell me about my Glow Plug Replacement
Glow plugs are heating elements used in diesel engines to warm the air in the combustion chamber, making it easier to start the engine in cold conditions. Over time, glow plugs can fail, making your vehicle hard to start or causing rough idling and smoke. Replacing faulty glow plugs ensures reliable cold starts and smooth engine performance.
What is a glow plug replacement?
This service involves removing worn or faulty glow plugs and installing new ones. In some cases, all glow plugs are replaced at once to maintain consistent performance across all cylinders.
Why do you need a glow plug replacement?
Without properly functioning glow plugs, your diesel engine may struggle to start, especially in cold weather. Faulty glow plugs can also increase emissions and reduce fuel efficiency.
Common signs you need a glow plug replacement
- Hard starting, particularly in cold weather
- Rough idling after startup
- White or black smoke from the exhaust
- Loss of power during acceleration
- Glow plug warning light illuminated on the dashboard
What happens during a glow plug replacement?
A mechanic will:
- Confirm faulty glow plugs using diagnostic tests
- Disconnect the battery to ensure safety
- Remove the old glow plugs carefully to avoid thread damage
- Install new glow plugs with correct torque
- Reconnect electrical connections
- Test start the engine to confirm smooth operation
How much does a glow plug replacement cost?
Glow plug replacement typically costs $250–$600, depending on the number of cylinders and labour involved. If the glow plug control module also needs replacing, costs may rise to $600–$1,200+.
Is it unsafe to drive with bad glow plugs?
While not immediately unsafe, faulty glow plugs can leave you stranded if the engine won’t start. They can also cause incomplete combustion, leading to smoke and higher emissions. Replacement is recommended as soon as symptoms appear.
