When to Change the Timing Belt and What Happens if It Snaps
Change the timing belt as specified by the manufacturer, typically every 60,000 – 120,000 km or after 5 – 6 years — whichever comes first. The belt controls the precise opening of the valves, so if it snaps on an interference engine the result is bent valves and major engine damage. Not sure of the interval for your car? Call us on
Replacement interval: mileage and years
Every manufacturer sets its own timing belt interval. It usually falls between 60,000 and 120,000 km, but the time limit matters just as much — 5 to 6 years. The rubber ages and cracks even on a car that covers very few kilometres. The rule is simple: replace it whichever comes first. You will find the exact interval in the service book, or we are happy to verify it by make and engine.
Warning signs of a worn belt
A timing belt rarely gives a clear warning, but some symptoms should not be ignored: a squealing or whistling noise from the timing area, rough or uneven idle, harder cold starts, or a light film of oil around the timing cover. Visible cracks, frayed edges or missing teeth on the belt are the final warning. If you notice any of these, do not put off the job — have the timing belt inspected right away.
Timing belt versus timing chain
Engines use either a timing belt or a timing chain. A belt is quieter and cheaper, but it has a defined lifespan and must be replaced on schedule. A chain is designed to last longer, yet it is not indestructible — a stretched chain or a worn tensioner shows up as a rattle, especially on a cold start. Which one your car has depends on the specific engine; we can confirm it from the VIN or the registration document.
Why you should not postpone it
Most modern engines are so-called interference engines — the pistons and valves share the same space in a precisely timed rhythm. If the belt snaps, the camshaft stops while the crankshaft keeps turning, and the pistons strike the open valves. The result is bent valves, damaged guides and, in worse cases, the pistons and cylinder head too. Repairing that damage costs many times more than a timely belt change — which is exactly why the interval is worth following to the letter.
What a timing belt job includes
A proper job is about more than the belt. It should also cover the water pump (where it is driven by the timing belt), the tensioner and idler pulleys, the tensioner itself and, where needed, the camshaft and crankshaft oil seals. We fit proven timing belt kits from reputable makers and set everything to the specified values. Replacing the whole set at once pays off — a single failing component can destroy your freshly fitted new belt.

On an interference engine the pistons hit the open valves, bending the valves and damaging the engine. The repair costs far more than a timely timing belt replacement.
If it is driven by the timing belt, absolutely. Replacing it together with the belt is cheaper and safer than dealing with it separately a few thousand kilometres later.
