When you need this service
- The belt is due for replacement: both mileage and the age set by the manufacturer count.
- There is no record of the last replacement: maintenance needs to be discussed for your specific engine.
- An unusual noise on start-up: it can have several causes and does not prove chain wear by itself.
- Another workshop recommended a replacement: bring the inspection result and the list of proposed parts.
What the work includes
- Timing belt replacement with a kit matched to your engine.
- Timing chain replacement; the components and any extra work depend on the design and condition.
- Confirming the idlers, tensioners and other parts the kit needs.
- Agreeing the consumables and fluids needed for the job.
Good to know
- Have the VIN, engine code, mileage and any service history ready.
- Confirm the type of timing drive and the parts the kit needs.
- Agree the cost of parts and labour, the time and any extra items before the work starts.
What the cost depends on
The cost depends on the model, access to the part, the amount of work and the parts chosen. For an estimate, tell us the make, model, year and the job you need. The final scope of the repair is set after the inspection.
Frequently asked questions
When should the timing belt be replaced?
The manufacturer sets the interval in years and kilometres for each engine. There is no single rule. If the history is missing, discuss maintenance separately.
Does a timing chain never need replacing?
Having a chain does not rule out the need for checks. The manufacturer's requirements, the history and the condition found all matter.
Should the water pump be replaced too?
It depends on the engine design, how the pump is driven and its condition. Confirm whether this is needed for your car.
Why does the cost of a timing job vary?
Access, the kit and the labour time differ between engines. An estimate needs exact details; ask for parts and labour to be priced separately.
