What Toyota engines have a timing chain?
When it comes to maintaining your Toyota vehicle, understanding whether your engine uses a timing chain or a timing belt is crucial. Timing chains and belts serve the same purpose: they synchronize the rotation of the crankshaft and camshaft to ensure proper engine function. However, timing chains are generally more durable and require less frequent replacement compared to timing belts. In this article, we’ll explore which Toyota engines are equipped with timing chains and why this matters for your vehicle maintenance.
Why Timing Chains Are Preferred
Timing chains are made of metal, making them more robust and long-lasting compared to rubber timing belts. Here are some key advantages of timing chains:
- Durability: Timing chains can last the lifetime of the engine with proper maintenance.
- Low Maintenance: Unlike timing belts, which typically need replacement every 60,000 to 100,000 miles, timing chains rarely require replacement.
- Reliability: Timing chains are less likely to fail unexpectedly, reducing the risk of engine damage.
Because of these benefits, many modern Toyota engines are equipped with timing chains instead of belts.
List of Toyota Engines with Timing Chains
Toyota has transitioned many of its engines to timing chains over the years. Below is a list of popular Toyota engines that use timing chains:
- 4-cylinder engines: Most modern Toyota 4-cylinder engines, such as the 2.0L 3ZR-FAE and 2.5L 2AR-FE, are equipped with timing chains.
- V6 engines: Toyota’s V6 engines, including the 3.5L 2GR-FE and 3.5L 2GR-FKS, use timing chains.
- Hybrid engines: Toyota hybrid engines, such as the 1.8L 2ZR-FXE found in the Prius, also feature timing chains.
- Diesel engines: Many Toyota diesel engines, like the 2.8L 1GD-FTV, are equipped with timing chains for added durability.
These engines are commonly found in popular Toyota models such as the Camry, Corolla, RAV4, Highlander, Tacoma, and Prius. If you’re unsure about your specific engine, consult your owner’s manual or contact a trusted mechanic.
How to Maintain a Timing Chain
Although timing chains are designed to last a long time, they still require proper maintenance to ensure optimal performance. Here are some tips to keep your timing chain in good condition:
- Regular oil changes: Clean engine oil is essential for lubricating the timing chain and preventing wear.
- Listen for unusual noises: A rattling or ticking sound from the engine could indicate a loose or worn timing chain.
- Inspect the chain tensioner: The timing chain tensioner helps maintain proper tension. If it fails, the chain may become loose.
By following these maintenance tips, you can extend the life of your timing chain and avoid costly repairs.
Conclusion
Many Toyota engines, especially those in newer models, are equipped with timing chains due to their durability and low maintenance requirements. If you own a Toyota vehicle, it’s worth checking whether your engine uses a timing chain or belt to plan your maintenance schedule accordingly.

Frequently Asked Questions
Which engines have timing chains?
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.
Does the Toyota Corolla Cross have a timing belt or chain?
Newer models use timing belts made of polyurethane and Kevlar for long life and durability. They can go as long as 100,000 miles although it's always a good idea to change it before then. Belt failure can cause extensive damage to the valves, pistons and other internal parts of the engine.
Does the 2025 Toyota Camry have a timing belt or chain?
Timing Belt Inspection/Replacement (if applicable): Depending on the engine type in your 2025 Camry, you may have a timing belt or chain. Timing belts require periodic replacement to prevent catastrophic engine damage. Consult your owner's manual for the recommended replacement interval.
Is a timing chain better than a timing belt?
A quieter engine is often more appealing to buyers, so the timing belt is installed to ensure a smoother sound. The longer lifespan of a timing chain is why they are chosen over timing belts – they very rarely break, but any problems that do arise are easy to catch before they reach the point of no return.
Does the Honda CRV have a timing belt or chain?
Honda CR-V and Civic models are equipped with a timing chain.
How long do Toyota timing chains last?
around 200-250k miles
Timing chains don't often need to be replaced on Toyotas. If they're at the point where they need to be replaced you'll often get a ton of correlation codes beforehand. They generally "go" at around 200-250k miles. If doing a timing chain, also replace the guides and the tensioners.
Which Toyota models have timing chains?
| Model | Year | Belt / Chain / Gear |
|---|---|---|
| GR Supra | 2020 | Chain |
| T100 | 1995-1998 | Chain |
| 1993-1998 | Belt | |
| Tacoma | 1995-2020 | Chain |
Does a 2017 Toyota Corolla have a timing chain?
If your Toyota Corolla is a model year 1998 or newer, it does not have a timing belt (it uses a chain instead). Corollas made between 1990 and 1997 use a timing belt. Toyota Corolla timing belts typically need to be replaced about every 60,000 miles.
How long will a Toyota timing chain last?
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.
Which is better, a timing chain or a belt?
Which Is Better? Though it's certainly a matter of opinion that's based largely on your priorities, it's generally felt that timing chains are better than timing belts. While most timing belts are supposed to be replaced every 60,000 to 120,000 miles, many timing chains end up lasting the life of the car.
