How do I know if my Vauxhall Astra's timing belt needs to be replaced?

I've been driving my Vauxhall Astra for about 5 years now and I'm not sure if I need to replace the timing belt yet. Can someone give me some advice on how to tell if it needs to be replaced?

If you're unsure, it's always best to check your owner's manual or consult with a trusted mechanic. However, a few signs that may indicate a need for a replacement include squealing noises from the engine, difficulty starting the car, or visible cracks or damage on the belt itself.

In general, timing belts should be replaced every 60,000-100,000 miles. If you're approaching this mileage and haven't replaced it yet, it's probably a good idea to schedule a replacement with a mechanic.

You can also do a visual inspection of the timing belt yourself. Look for any fraying, cracking, or signs of wear. If you notice any of these, it's time to replace the belt.
