What is the lifespan of the Vauxhall Insignia timing belt and when should it be replaced?

I recently bought a used Vauxhall Insignia and I'm not sure when the timing belt needs to be replaced. I want to make sure it's properly maintained to avoid any potential engine damage. Can someone advise me on the recommended lifespan of the timing belt and when it should be replaced?

The lifespan of a timing belt can vary, but it is generally recommended to replace it every 60,000-100,000 miles. However, it's always best to check your owner's manual for the exact mileage and interval for your specific model of Insignia.

If your Insignia has a diesel engine, you'll need to replace the timing belt every 4-5 years or approximately 60,000 miles, whichever comes first. For petrol engines, it's recommended to replace the timing belt every 6 years or 100,000 miles.

It's crucial to replace the timing belt before it fails, as a snapped belt can cause severe engine damage. You can also look for signs of wear and tear, such as cracks, fraying, or excessive slack. If you're unsure, it's always best to consult a mechanic.
