Frequently asked questions on glow plug repair

What happens when my glow plug fails?

When a glow plug fails, your engine might be hard to start, producing more smoke, engine misfires, and poorer performance.

How often should I replace my glow plugs?

Glow plugs typically last between 60,000 to 100,000 miles. Read your car’s manual and have them checked regularly.

Can I replace glow plugs myself?

It’s tricky and needs specific tools, so it’s best to let a mechanic handle it.
