There is a growing list of cars that do not have a timing belt, including the Volkswagen Polo from 1967-76, the Toyota RAV4 from 2006-12, and the Mercedes-Benz 300SE from 1991-95. Additionally, many late model engines designed by BMW, Honda, Ford, and other automotive manufacturers no longer contain timing belts as part of the engine design.
This is due to the fact that timing belts are one of the most costly and complex components of an automobile engine, and often need to be replaced every 60,000 miles or so. As a result, many car makers have opted for timing chains, which are much more durable, require less maintenance, and are less expensive.
So, even though it may vary by model and make, an increasing number of cars are now being manufactured with timing chains instead of timing belts.

Can a car go without a timing belt?
No, a car cannot go without a timing belt. A car’s timing belt is an essential part of the engine, responsible for synchronizing the rotation of the camshaft and crankshaft. Without the timing belt, the engine is not able to maintain optimal engine timing, which can lead to a variety of mechanical problems.
The most serious risk associated with driving a car without a timing belt is a seized engine, which is caused by the camshaft and crankshaft spinning wildly and coming into contact with each other, which causes major engine damage.
Additionally, a damaged or missing timing belt can also cause stalling, diminished engine performance and other mechanical problems. For these reasons, it is advised against driving a car without a timing belt.
What’s the longest a timing belt can last?
The longevity of a timing belt is dependent on several factors, such as the make and model of the vehicle and the environment in which it is driven. Generally speaking, the longevity of a timing belt is typically between 60,000 miles to 100,000 miles.
However, some belts may last longer or shorter, depending on the specific factors previously mentioned. It is recommended that drivers take extra care of their timing belt by following the vehicle manufacturer’s recommended service intervals and using proper parts and accessories.
Additionally, proper maintenance and service can also extend the life of a timing belt.
Is it better to have a timing belt or chain?
It really depends on the type of engine you are using. Generally, timing belts are quieter and require less maintenance, while timing chains are more durable and have a longer lifespan. Timing belts use an elastic material, usually rubber, and often require replacement after a certain number of miles, typically anywhere from 60,000-100,000 miles.
Timing chains however, are a metal chain which pull the camshaft in sync with the crankshaft, and typically do not have a lifespan limit, but they may require adjustment over time.
For this reason, it is generally advisable to use a timing belt when possible. Unless you are willing to perform periodic maintenance to your engine and replace your timing belt when necessary, then a timing chain is the better option for a longer lasting solution.
Can a timing belt last 30 years?
No, it is highly unlikely that a timing belt will last 30 years. A timing belt typically only lasts between 50,000 and 100,000 miles, depending on what kind of vehicle you have. The best way to extend the life of any timing belt is to have it regularly serviced every 20,000 to 40,000 miles, depending on the manufacturer’s recommendations.
In addition, regular inspections by a professional mechanic can help detect if the belt is showing signs of wear, which can help prevent more costly damage down the road. With regular maintenance, a timing belt can last up to eight years, but 30 years is simply too long.
How do I know if my car has a timing belt?
The best way to determine if your car has a timing belt is to consult the car’s owner’s manual as the exact location and type of belt (timing or serpentine) differs among car makes and models. Alternatively, you can open the hood and look for a rubber belt or chain connecting the crankshaft to the camshaft.
A visual inspection may also help you identify any potential issues with the belt, such as fraying or corrosion. Additionally, you can look for service records related to your vehicle’s timing belt. These typically detail when the belt was last changed and when it needs to be inspected or replaced.
If you are unsure whether your car has a timing belt or not, it’s best to contact a mechanic for assistance.
How often do timing belts actually break?
Timing belts rarely break, but it does depend on how often they are maintained. Every vehicle is different and will require different timing belt change intervals, ranging from anywhere between 40,000-100,000 miles.
Generally, a timing belt should be replaced once it has clocked up the mileage set by the manufacturer. It is important to check the owner’s manual for an accurate recommendation for when your timing belt should be changed.
Such as an engine misfire, difficulty starting the engine, a whining noise coming from the engine, or decreased fuel efficiency. If you are experiencing any of these warning signs, it is important to take your vehicle to a qualified mechanic who will be able to diagnose the problem and tell you if the timing belt needs to be replaced.
If your timing belt is well maintained and not neglected, then it will rarely break. However, it is still important to check and replace your timing belt according to the manufacturer’s recommendations to protect your engine and ensure its long-term health.
What happens if car timing belt breaks while driving?
If a car’s timing belt breaks while driving, it can cause extensive damage to the engine. When the timing belt breaks, the pistons in the engine can hit the valves, bending or breaking them. The engine can also suffer damage from a lack of oil or coolant flow, resulting in overheating.
In severe cases, the broken timing belt can damage the head, cylinder walls, and the crankshaft. The timing belt is responsible for keeping the camshaft and crankshaft in sync, so when it is broken, it can cause the pistons to move in the wrong timing, potentially resulting in engine failure.
Additionally, if the timing belt breaks, the valves can contact the pistons and that can cause additional damage to the engine. Not only will this require costly repairs, it also renders the vehicle non-operational until repairs have been made.
Do cars with timing chains need to be replaced?
The answer to whether cars with timing chains need to be replaced depends on the age of the vehicle and its individual maintenance needs. Generally speaking, most automakers recommend replacing a timing chain every 100,000 miles or more, though this can vary from manufacturer to manufacturer.
However, many vehicles now come with metal timing chains, which are extremely durable and considered a lifetime component. In addition, if a vehicle is well maintained, experienced mechanics might suggest the timing chain does not necessarily have to be replaced even after 100,000 miles.
In any case, if the timing chain on your car has been neglected, it should be inspected by a certified mechanic. A worn timing chain may cause issues with the valve timing, resulting in reduced power, increased emissions, and a decrease in fuel economy.
Additionally, if the timing chain jumps a tooth or breaks, it will cause severe engine damage. Therefore, it is best to have the timing chain inspected periodically to ensure it is in good working condition.
If it is found to be worn or showing signs of fatigue, it should be replaced.
How often do you need to replace a timing belt?
The answer to this question varies depending on the make and model of the vehicle, as well as the year it was manufactured. Generally, though, most vehicles will require their timing belt to be replaced every 60,000 to 90,000 miles, but it is still best to check with your owner’s manual or a professional mechanic to determine the exact timing for your specific car.
Additionally, it is important to remember that if you experience a delay in replacing your timing belt, the belt and associated components (like the water pump) may be damaged.
