The Sienna has long offered an excellent family van at a reasonable price to American families. It was originally billed as the “Camry of minivans.”
Timing chains and interference engines are standard equipment on all Toyota Siennas built after the 2007 model year, while non-interference engines and timing belts are standard equipment on all Siennas built before 2007.
For instance, the timing chain is used in the 2021 Toyota Sienna A25A-FXS 2.5L 4-Cyl Hybrid, 186 (gas only) hp, and the timing belt is used in the 2006 Toyota Sienna 1MZ-FE 3.3L V6 230 hp option.

Has a 2009 Toyota Sienna timing chain or belt?
This engine has a timing chain if it is a 2009 model, if that is the case. First of all, there is never a need to replace that. If your current service technician asks you to replace a timing belt on a car without one, do two things right away.
Toyota switched to timing chains from timing belts at what point?
Therefore, the timing belt or chain is in charge of synchronizing the crankshaft and camshaft of the engine. This enables smooth engine operation and prevents engine damage by enabling the pistons and valves to move at the proper timing. The engine cannot function properly and may possibly sustain significant internal engine damage if the timing belt or chain fails.
Over the years, Toyota has used both timing belts and chains in their vehicles. However, since 2005, Toyota has primarily used timing chains in their automobiles. Even though they can be noisier and require adequate maintenance, timing chains can survive for a very long time, so owners won’t need to replace them regularly. Timing belts, on the other hand, don’t need as much upkeep, but drivers must replace them more frequently after around 65,000 miles. Before 2005, Toyota mostly used the timing belt in its vehicles.
We hope the list above has made it easier for you to determine whether your Toyota has a timing chain or belt.
Timing belt or chain: which is superior?
Timing belts typically last less time than timing chains. Timing belts are made of rubber, which isn’t as strong as metal, but chains are made of metal, and this is the simple explanation for why this is the case. Timing belts are not weak, but they will probably need to be replaced at some point, whereas a chain can last the lifetime of the car.
Timing belts typically need to be replaced in the mileage range of 55,000 miles (about 90,000 km) and 90,000 miles (roughly 150,000 km). Therefore, a timing belt is still a very reliable and significant component of your car.
Whether your car has a timing chain or belt, it’s critical that you watch for any symptoms of wear and strain and take appropriate action. Depending on the sort of engine you have, a broken timing belt can have disastrous results. You could be better off searching to get a new vehicle if the repairs are too expensive to be practical.
Which automobiles use timing chains rather than belts?
Timing chains are being installed in more and more vehicles. The majority of Mercedes and BMW vehicles come with timing chains.
A non-exhaustive list of vehicles that can have timing chains installed is provided below:
- a lot of Mercedes
- Every Cadillac
- Every SAAB has a turbocharged engine.
- Duster, Sandero, and Sandero Stepway from Dacia
- Jazz Honda
- Corvette by Chevrolet
- Skyactiv-G engine in Mazda
- 159 Alfa Romeo
- many BMWs
You may physically inspect your car’s timing belt or chain by removing a cover at the end of the engine, consulting your owner’s manual, or asking your mechanic. The timing chain is easily identified by its metal links when the cover is removed with the proper tool, whereas the belt is comprised of rubber and is considerably more flexible.
Ask your mechanic: “How do I tell whether my automobile has a timing belt or chain? if you are still unclear.
You won’t typically need to replace your car’s timing chain. Poor lubrication is likely to have ruined a chain that has to be replaced.
If the timing chain is determined to be damaged, it’s critical that you hire a reputable expert to handle the repair. In extreme cases, the mechanic will even need to completely remove the engine to get to the timing chain. If the timing chain breaks, it may harm other engine components like the valves, making the repair more involved and pricey.
There is a timing belt on the 2011 Toyota Sienna, right?
It has three chains. Like on earlier models with a timing belt, there is no required maintenance for the chains. Just be sure to change the oil at regular intervals, and the chains should last the engine’s lifetime.
When should the Toyota Sienna’s timing belt be changed?
Referring to Timing Belt Replacement Although they can last up to 100,000 miles, it’s always a good idea to change them before that. The valves, pistons, and other internal engine components can sustain significant damage in the event of a belt failure.
A timing belt is present in a 2005 Toyota Sienna, right?
An engine that cranks but won’t start due to a broken timing belt might also suffer severe engine damage. Use genuine Toyota parts when replacing the timing belt on your 2005 Toyota Sienna for maximum dependability. 199607 through 199908.
What signs or symptoms point to a timing chain failure?
symptoms of a defective timing chain
- When the engine is running or idles, there is a rattle. Unusual rattling noises when the engine is started or when the brakes are applied are a common sign that a timing chain in a car is damaged.
- Engine Misfire.
- Engine oil with contamination.
- Check Engine indicator.
- not being able to start the engine.
How can timing chain failure be avoided?
- Check your timing chain cover for leaks frequently.
- Make that the engine oil is not running low.
- Avoid letting the engine get too hot; if it does, don’t drive.
Can I drive on a bad timing chain?
The timing chain expands over time, as was already mentioned. Even though you can still drive with an old timing chain, we advise replacing it as soon as you observe stretch or other signs of failure.
A faulty chain can jump many teeth or entirely break if you drive on it for an extended period of time and it continues to strain, which can seriously harm your engine’s internal components.
How can I tell if I need to replace my timing chain?
Timing chains do not require routine replacement, but timing belts do. The timing chain shouldn’t need to be changed unless it has been harmed, overworked, or otherwise compromised. Your car will most likely experience one or more faults if there is a timing chain issue.
A broken timing chain will show the symptoms listed below:
- The vehicle won’t start
- Misfiring engines and sluggishness
- The engine shakes or rattles while it is idling.
- Starting the car is challenging.
- The check engine light is on.
- The timing chain has noise.
You might hear noise coming from the area where the timing chain cover resides. This noise is frequently the result of a loose timing chain, which may be brought on by a broken timing chain tensioner, guide, or other issues. More serious issues will arise if you ignore the early warning signs, so be sure to check the timing chain as soon as you hear a noise coming from where it is mounted.
How much does it cost to repair a timing chain?
How much does it cost to replace a timing chain? Timing chains can be changed by a professional for $1,600 to $1,800 or you can do it yourself for $600 to $800. The cost is significant because it’s challenging to replace this component.
Timing belt on 2006 Toyota Sienna?
For robustness and long life, more recent models use timing belts consisting of polyurethane and Kevlar. Although they can last up to 100,000 miles, it’s always a good idea to change them before that. The valves, pistons, and other internal engine components can sustain significant damage in the event of a belt failure.

How can I lengthen the lifespan of my timing chain?
Timing chain vibration is prevented by using chain guides and silencers. Each of these parts ages as well. How can you tell if the timing chain needs replacing?
When the timing chain is worn, the engine frequently feels sluggish, has little power, or is difficult to start. Perhaps the Check Engine light will also come on. This is due to the fact that as the chain ages, it stretches and the ignition and valve timing advance more.
Numerous noises coming from the engine’s timing chain cover area can also be caused by a worn timing chain, chain guides, or chain tensioner. The timing chain noises can be whirring, whining, buzzing, whining, or rattling.
If the timing chain needs to be replaced due to wear, a new tensioner, guides, and other chain drive mechanism components are often included with the kit. The motors of many cars have two or even three chains, and frequently your auto repair shop will advise replacing all the chains at once.
Depending on the vehicle model, timing chain replacement costs might range from $370 to $1,500.
Finding the right process to set the timing when a new chain is inserted is necessary if you intend to replace the timing chain yourself. This kind of information can be found in the service handbook for your car.
It’s rather simple to replace the timing chain in old-style pushrod engines. If you drive a new front-wheel drive vehicle with a transversely positioned engine, you may not have such luck because the engine compartment may be relatively small. In a V6 engine, it becomes considerably more challenging.
Maintaining your engine properly and changing the engine oil at specified intervals will help you avoid timing chain issues. Oil filters and engine oils of the highest caliber should be used. The timing chain will always be lubricated if the oil level is maintained at the right level. Given that many modern engines are known to use oil, this is extremely crucial. A timing chain in a well-maintained engine can last up to 300,000 miles or even more.
What occurs if your timing chain malfunctions?
An engine with a broken timing chain will either not start or fail while being driven. The engine won’t start if the belt is already broken since there won’t be adequate compression. The pistons will sustain damage by coming into touch with the valves if it breaks or leaps while being driven. The actual valves will bend, possibly ruining the engine.
