How do I know if my car has a timing belt or chain?
Knowing whether your car has a timing belt or a timing chain is important for maintaining its engine's health and longevity. A timing belt is a rubber or reinforced rubber belt that connects the crankshaft to the camshaft, while a timing chain is a metal chain that serves the same purpose. Determining which one your car has can help you plan for necessary maintenance and avoid costly repairs down the line.
Identifying a Timing Belt
Here are some signs that your car has a timing belt:
- Location: The timing belt is typically located at the front of the engine, often behind a cover or panel that needs to be removed to access it.
- Replacement Schedule: Timing belts typically need to be replaced every 60,000 to 100,000 miles, as recommended by the manufacturer. This is a critical maintenance task to prevent the belt from breaking and causing severe engine damage.
- Visibility: If you can see a ribbed, rubber-like belt when you look at the front of the engine, it's likely a timing belt.
If your car has a timing belt, be sure to follow the manufacturer's recommended replacement schedule to avoid costly engine repairs.
Identifying a Timing Chain
Here are some signs that your car has a timing chain:
- Location: The timing chain is typically located deeper within the engine, often requiring the removal of additional components to access it.
- Replacement Schedule: Timing chains are designed to last the lifetime of the engine and generally do not need to be replaced unless there is a problem.
- Visibility: If you can see a metal chain when you look at the front of the engine, it's likely a timing chain.
Timing chains are generally more durable and longer-lasting than timing belts, but they can still experience issues over time, such as wear or stretching. If you suspect a problem with your timing chain, it's best to have a mechanic inspect it.
Consulting Your Owner's Manual
The best way to determine whether your car has a timing belt or chain is to consult your owner's manual. The manual will provide specific information about your vehicle's engine and the type of timing system it uses. This information can help you plan for any necessary maintenance or replacement tasks.
What are the signs of a timing belt going bad?

- Ticking noise from under the hood when the engine is running.
- The engine doesn't start.
- The engine misfiring while driving.
- Oil leaking from the front-side of where the motor is under the hood.
- Hydroplaning while driving in wet weather conditions.
- Check engine light is on.
Which cars have timing chains instead of belts?

- Most BMWs.
- Dacia Sandero (TCe engine)
- Suzuki Swift.
- Most MINIs.
- Most Audi petrol models.
- Toyota Yaris.
- Honda Jazz.
How often do timing chains need to be replaced?
between 80,000 and 100,000 miles
When Should It be Replaced? Unless your engine has a specific replacement interval, the commonly accepted mileage is between 80,000 and 100,000 miles. However, the timing chain isn't necessarily a maintenance item and can last the engine's life, provided you change the oil regularly and maintain the rest of the engine.
How do I know if my car is timing belt or chain?
You can open the bonnet of your car and inspect the engine to find out which your car has. Check to see if there is a plastic cover on the right or left side of your engine, as this will indicate that your car uses a timing belt. If no plastic is visible on the side, then your car uses a timing chain.
What vehicles have timing chains?
Luxury Cars
- Mercedes-Benz: Many Mercedes models, especially those with V6 and V8 engines, use timing chains.
- BMW: BMW models like the 3 Series and 5 Series and vehicles with inline-six engines often come with timing chains.
- Audi: The A4 and A6, especially with V6 engines, frequently feature timing chains.
How do I know if my car has a timing chain issue?
Specifications. It could break a broken belt will fail to rotate the crankshaft. And camshafts together resulting in the starter only rotating the crankshaft.
How easy is it to check a timing belt?
A further way to check is to press a fingernail or the tip of a screwdriver gently onto the belt. If the pressure does not leave a mark, it means the rubber is becoming too stiff. As the cambelt can be difficult to get to, a visual and physical check is best done by a professional.
What lasts longer timing chain or timing belt?
Timing chains generally have a longer lifespan than timing belts. The reason for this is quite simple: chains are made from metal, whilst timing belts are made from rubber, which simply isn't as strong.
What is the life expectancy of a timing chain?
between 80,000 and 100,000 miles
Unless your engine has a specific replacement interval, the commonly accepted mileage is between 80,000 and 100,000 miles. However, the timing chain isn't necessarily a maintenance item and can last the engine's life, provided you change the oil regularly and maintain the rest of the engine.
What are symptoms of a bad timing chain?
Misfiring, poor idle, and rough running could mean the chain has jumped a tooth and the timing is off. Replacement is urgent, because the chain could break at any point, and the engine could be damaged from incorrect valve timing. Metal shavings or visible pieces of chain in the oil would be another potential sign.
