Timing chains are rarely used in new cars; instead, timing belts are. Timing chains create a lot of noise, even though they are more resilient than belts and can cause engine damage if they break.
Additionally, oil pressure provides tension force to the tensioners on engines with timing belts. Low pressure will cause the chain to break. Timing belts, on the other hand, operate more quietly and efficiently.
The range of their service lives is 60,000 to 100,000 miles. The tensioner and the pulley for the water pump must also be replaced when the belt is. The overall cost is increased by this additional replacement.
Timing chains are more resilient and can outlast the engine. They ought to be oiled frequently to lengthen their lifespan and lower noise and friction.
Instead of a cambelt, newer Toyota 4Runner models are fitted with a timing chain. This is as a result of their enduring toughness.

Which 4Runner models come with timing belts?
All Toyota 4Runner vehicles will use an interference engine and timing chain from 2010 until 2021. The 4.7L 4Runner has a timing belt and interference engine, while the 4.0L 4Runner vehicles from 2003 to 2009 have timing chains and interference engines.
Timing chains and interference engines are standard on all 4-cylinder 4Runners from 1984 to 2002, whereas timing belts and non-interference engines are available on V6 versions.
In contrast to the 2009 Toyota 4Runner 4.7L V6 268 horsepower (2UZ-FE) option, the 2021 Toyota 4Runner 4.0L V6 270 hp (1GR-FE) option includes a timing chain.

Timing Belt Basics
Maintaining the timing (synchronization) between the crankshaft and the camshaft is the major goal of the timing belt or timing chain (s).
While a timing chain resembles a bicycle chain, a timing belt is comprised of a rubber composite.
Timing belts deteriorate over time, thus they need to be replaced at the intervals recommended by the manufacturer. Serious engine damage may ensue from a failing timing belt.
Even though a timing chain will inevitably deteriorate with time, it should nonetheless undergo regular checks.
Is there a timing belt or chain on the 2007 Toyota 4Runner?
sized engine? The three chains on the 4.0L 6 cylinder should endure the duration of the engine. At intervals of 90,000 miles, the timing belt on a 4.7L 8 cylinder should be changed together with any other parts.
Has the fourth-generation 4Runner a timing belt or chain?
Timing chains were employed in the 4.0 V6 in 2008.
Since 2003, when the v6 4.0 replaced the previous 3.4 v6, which did utilize a timing belt, the v6 has been powered by a chain.
Since 2003, when a v8 was a 4runner option, the 4.7 V8 in such vehicles used a timing BELT.
Because there is no advised replacement interval and chains often last the lifetime of the automobile or several hundred thousand miles, having one is preferable.
Now, regular maintenance calls for replacing the timing belt. I’m not sure what they advise for that specific year, but generally the timing belt needs to be serviced every 100K miles, which will cost you at least $1000. I own two v6 4runners, one with 203K miles and the other with 281K miles.
How frequently should a Toyota 4Runner timing belt be replaced?
Timing belts are important, but unless your Toyota owner’s handbook specifically advises it, they don’t need to be replaced on a regular basis. Between 60,000 and 100,000 miles, some automakers advise changing the timing belt, while others don’t. Many timing belts available now can last 100,000 miles or more before they need to be replaced.
Has the 4.0-liter Toyota V6 got a timing belt?
All four-cylinder Toyota Tacomas feature interference engines with a timing chain as standard equipment. Timing chains and interference engines are standard in V6 Toyota Tacomas from 2005 through 2021. Timing belts and non-interference engines are standard on V6 models from 1995 to 2004.
In contrast to the 2004 Toyota Tacoma 3.4L V6 190 hp (5VZ-FE) option, the 2021 Toyota Tacoma 2.7L 4 Cyl. 159 hp (2TR-FE) option has a timing chain.

Timing belts or chains: which is superior?
Prior to making a purchase decision, you may be examining the specifications of various cars. What is the displacement of the engine? What type of brakes is it equipped with? How is the transmission handled? Exists a long-range AEB with it? Before making a decision, there are several factors you can compare between each car. We’ll be discussing timing chains and belts today.
The camshaft and crankshaft rotations are synchronized using timing chains or belts. As a result of the Overhead Cam (OHC) arrangement used by the majority of modern engines, the crankshaft and camshaft must be connected by a belt or chain. Timing belts or timing chains are also necessary for engines with push rod configurations (although shorter in length).
Some contend that the greater lifespan of timing chains makes them superior. Some contend that the cheaper replacement costs and quieter operation of timing belts make them superior. The problem is that when buying a car, you cannot select whether it will have a timing chain or belt. If you liked one timing system over the other, you’d have to purchase a new vehicle.
Consider a Perodua Myvi and a Proton Iriz as examples. An Iriz has a timing belt, whereas a Myvi has a timing chain. Does that mean that one car is better than the other? Does one require less upkeep than the other?
A: Timing chains outperform timing belts in strength. Timing links are also more durable. Timing belts are more affordable, simpler to replace, and quieter than timing chains.
A: Yes. usually only slightly. Since the gear teeth are worn out as well, fixing the timing chain also necessitates changing certain gears. Timing chains, however, do not require as frequent replacement as timing belts.
A: Yes. The engine oil must lubricate the timing chains. As a result, they live in a more contained structure. Consequently, it will take more effort to reach the timing chain. Timing belts are easier to service because they often only have a plastic cover to protect them.
A: Yes. The sprockets and gear teeth mesh. Over time, the chain stretch lengthens and the gear teeth begin to wear out. They eventually need to be replaced. A timing chain replacement does not, however, have a set replacement interval.
When the timing chain stretch could potentially harm the engine, the engine warning light will typically on. If that happens, turn off the engine. Chain strain could result in the chain jumping a gear tooth, throwing off the timing of the pistons and valves and resulting in some rough idling.
A: Yes. They must be replaced as a result around every 100,000 kilometers. Timing belts that aren’t maintained could rupture and seriously harm the engine (especially interference engines). Teeth that are worn down could potentially cause timing belts to slip.
What is the worst thing that could happen if the timing chain or belt breaks?
This is true for interference engines, which are smaller and more effective in their design. Timing belts tend to snap more frequently, although in most cases, if you change them on schedule, this issue shouldn’t arise.
A combination. A timing belt is used by an earlier RB26DETT. A timing chain is used by more recent VR38DETTs.
Timing belts and chains aren’t even used in some vehicles, like the Ferrari Enzo. Instead, they synchronize the valves with the engine rotation using a number of timing gears. Compared to timing chains, timing gears are louder.
To sum up:
- Timing chains are more expensive than timing belts but have a longer lifespan.
- Using one over the other has no impact on performance or fuel economy.
- Timing belts were mostly used in autos due to their lower cost. They function just as well.
- Timing chains may sag over time, resulting in gear teeth that “jump.”
- Teeth on timing belts can wear out and move. Timing belts are also more susceptible to breaking.
- Timing belt or timing chain failure can have disastrous effects on the engine.
- The lower operating noise of timing belts is an additional advantage.
No matter what type of timing system your car has, you should undertake routine maintenance to keep an eye on the condition of your timing belt or chain.
Should Toyota timing chains be changed?
Because it requires engine oil for lubrication, a timing chain operates inside the engine. Depending on the vehicle, a timing belt normally needs to be replaced between 40,000 and 100,000 kilometers. The fix costs a few hundred dollars. It is not necessary to replace a timing chain unless there is an issue with it.
Is there a timing belt or chain on a 2010 Toyota?
system (the same function, but uses a set of gears rather than belts or chains). Timing chains are used in the 19931997 straight-six engine. The V8 models from 1998 to 2007 make use of timing belts. While the V8 versions from 20082011 and from 20132020 employ timing chains.
- 20012009 4.7L V8 Sequoia Timing belts are used in Sequoia. Timing chains are used in both the 20102012 4.6L V8 and the 20082020 5.7L V8 models.
Is there a timing belt or chain on a 2012 Toyota?
AutoTrader: The 2.5-liter inline 4-cylinder and 3.5-liter V6 engines in the 2012 Toyota Camry use timing chains rather than belts. This is critical since a rubber timing belt must typically be replaced every 75,000 to 90,000 miles, necessitating a high mechanic charge.
