Your cambelt is one of the hardest working bits of your engine, driving vital engine components over hundreds of millions of revolutions and so is recommended for change every 5 years.
If your cambelt brakes, your engine could suffer major damage, making your vehicle undrivable, so it is a wise change to make. Plus it is covered by a 2 year warranty with unlimited cover for consequential engine damage should it snap in operation.
In addition, it is common for your water pump to fail after a new cambelt is fitted due to the extra tension, that is why we are offering you the chance to get both components changed at the same time, saving you the extra cost at a later date.
