Do any cars still use timing belts?
Yes, many cars still use timing belts, also known as cambelt or timing chain, as a critical component in their engine design. Timing belts play a crucial role in synchronizing the opening and closing of the engine's valves with the movement of the pistons, ensuring optimal performance and efficiency.
What is a Timing Belt?
A timing belt is a reinforced rubber belt that connects the crankshaft to the camshaft(s) in an internal combustion engine. It ensures that the engine's valves open and close at the correct times, allowing the engine to operate smoothly and efficiently. Timing belts are typically made of durable materials like reinforced rubber or a combination of rubber and fabric, and they are designed to last for a specific number of miles or years, as recommended by the vehicle manufacturer.
Why Do Some Cars Still Use Timing Belts?
Timing belts are still used in many modern cars for several reasons:
- Cost-Effective: Timing belts are generally less expensive to manufacture and install than the alternative, timing chains.
- Compact Design: Timing belts are often more compact and take up less space in the engine compartment, allowing for more efficient engine packaging.
- Quieter Operation: Timing belts tend to operate more quietly than timing chains, which can produce more noise as they wear over time.
- Maintenance Schedule: Timing belts typically need to be replaced at regular intervals, as recommended by the manufacturer, to prevent potential engine damage. This allows for more predictable maintenance planning.
However, it's important to note that some manufacturers have been transitioning to timing chains in recent years, as they can often last the lifetime of the engine without needing replacement.
Vehicles That Still Use Timing Belts
Many popular and widely-sold vehicles still utilize timing belts in their engine designs, including:
- Toyota Camry
- Honda Civic
- Subaru Outback
- Volkswagen Jetta
- Hyundai Sonata
- Kia Optima
It's always best to consult your vehicle's owner's manual or speak with a qualified mechanic to determine if your car uses a timing belt and when it should be replaced.
Which cars do not have timing belts?
Vehicles that have a timing chain instead of a cambelt include:
- Most BMWs.
- Dacia Sandero (TCe engine)
- Suzuki Swift.
- Most MINIs.
- Most Audi petrol models.
- Toyota Yaris.
- Honda Jazz.
Do any new cars still use timing belts?
Many modern passenger cars have either a timing belt or a timing chain. Generally speaking, timing belts have the advantage of being quieter and cheaper to produce and replace, while timing chains typically have a longer lifespan.
What engines still use a timing belt?
Brands That Still Use Timing Belts
Here are a few brands and models that still utilize timing belts: Honda: Models like the Honda Accord (V6 engines), Odyssey, and Pilot still rely on timing belts. Subaru: Some older Subaru models, such as the Forester and Outback, have timing belts.
When did cars stop using timing belts?
Timing belts were common on mass-production cars until the 1970s and 1980s, however since the 1990s timing chains have become more common due to the replacement intervals required when using timing belts.
