How often should I change the glow plugs in my Vauxhall Vivaro?

I noticed that my Vauxhall Vivaro has been having trouble starting in the mornings. I suspect it may be an issue with the glow plugs. How often should I change them to ensure optimal performance?

Glow plugs should generally be replaced every 50,000 miles or 4-5 years, depending on your driving habits and the quality of the plugs.

If you notice issues with the starting performance of your vehicle, it is best to replace the glow plugs sooner rather than later to avoid further damage to your engine.

I recommend checking your owner's manual for specific guidelines on when to replace the glow plugs. Remember, it's better to err on the side of caution and replace them sooner rather than later.
