What is a timing belt?
The timing belt is a crucial component that synchronizes the rotation of the engine's crankshaft and camshafts. This ensures that the engine's valves open and close at the exact right moment relative to the pistons. If this synchronization is lost, the engine cannot run, and in many vehicles, the pistons will actually strike the valves, causing catastrophic damage.
Unlike the serpentine belt, which you can see on the outside of the engine, the timing belt is usually hidden behind a protective cover, making it impossible to check visually without disassembly.
When should it be replaced?
Timing belts have a strict replacement schedule, typically between 60,000 and 100,000 miles, as specified by the manufacturer. You should find this in your owner's manual under the 'scheduled maintenance' section. Never exceed this interval; it's a gamble you will eventually lose. This is a maintenance item, not a 'wait-until-it-breaks' item.
If you are unsure if your belt has been replaced, have a professional inspect your service records or consult with us to determine the best course of action.
What happens if it breaks?
In an 'interference' engine, the valves and pistons occupy the same space at different times. If the timing belt snaps, the timing is lost, and the pistons will slam into the valves while they are still open. This usually results in bent valves, damaged pistons, and sometimes a destroyed cylinder head. The cost to repair this is thousands of dollars, often exceeding the value of the car. In some cases, the engine is a total loss.
This is why timing belt maintenance is absolutely critical.
Are there signs of trouble?
Unfortunately, there are rarely early warning signs of an impending timing belt failure. The belt is designed to work until it doesn't. You might notice an odd sound from the front of the engine, or perhaps the engine running a bit rough if the belt has stretched slightly, but often there is no warning at all. This is exactly why following the manufacturer's recommended interval is your only reliable protection.
Do not wait for symptoms; follow the mileage or age-based schedule.
The water pump connection
In many vehicles, the water pump is driven by the timing belt. Because the water pump is just as critical and the labor required to access it is the same as the timing belt, it is industry standard to replace both at the same time. If the water pump fails shortly after replacing the timing belt, you'll have to pay for all that labor again.
We always recommend doing the full 'timing belt kit' to ensure your entire system is reliable.

Frequently asked questions
Does my car have a timing belt or a timing chain?
It depends on the engine. Some have belts, some have chains. Chains are designed to last the life of the engine, but belts must be replaced.
Is it really that expensive?
It is a major service, but it is much cheaper than replacing a ruined engine after a timing belt failure.
What is an 'interference' engine?
An interference engine is one where the pistons can strike the valves if the timing is incorrect. Most modern engines are interference types.
How long does the service take?
Because of the complexity, it often takes a full day of labor.
