Sadly in 99% of cases you will only know if there is an issue with the cambelt when it breaks! This can occur at any time, at any speed and usually at the most inconvenient time and place. This is why manufacturers give recommended replacement intervals, both in terms of age and mileage. It is preventative maintenance that should never be overlooked.

On average, cambelt change times can range from 1.5 to over 5 hours with an average of 2.7 hours.

If you have purchased a second hand vehicle and it has no timing belt change history, such as a garage invoice, then it is important to err on the side of caution and have it replaced as soon as possible,

On many engines, the water pump is driven by the belt as well. If this is the case, it is imperative to have it replaced at the same time. There are two reasons for this, firstly, the water pump is a pulley and bearing that forms part of the circuit the belt travels around and should it fail, then the belt will come off and that is the same as it breaking. Also, water pumps are prone to seizing, which again will break the belt.

The second reason is that should the water pump fail (and not damage the belt etc) and require replacing, then the timing belt would have to be renewed at the same time, so its best to have a new one fitted as a preventative course of maintenance.

Most mechanics will not carry out the work unless the pump is replaced in the situation as they know the consequences!

Typically no, Wales mobile mechanics cannot do a cambelt or timing belt change at your home or office, because the repair may need to be carried out on a ramp, and may need specialist equipment. Also, the time involved to carry out the work may make it more practical to carry out the work at a garage.
