How do I know when to change the timing belt on my Vauxhall Combo Life?

I have a Vauxhall Combo Life and I am wondering when I should change the timing belt to avoid any engine damage. I have been driving it for 3 years now and have 45,000 miles on it. Should I change it at a certain mileage or is it based on time?

Timing belt replacement is usually based on time rather than mileage. It is recommended to replace it every 5-7 years, even if you haven't reached the recommended mileage yet. This is because over time, the rubber in the timing belt can deteriorate and lead to major engine damage if it snaps while you are driving.

I would recommend getting your timing belt checked by a certified mechanic. They will be able to tell you the condition of your belt and advise if it needs to be replaced. It's better to be safe than sorry when it comes to your engine.

In general, it's recommended to replace the timing belt every 60,000-100,000 miles. However, it's always best to consult your vehicle's manual for the specific mileage recommendation for your Vauxhall Combo Life.
