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.

Is there a timing chain or belt on a 2008 Toyota Tundra?
The only engine in the Gen2 Tundra that features a timing belt is the 4.7L engine. After 2008, the 4.6L engine, which also has a timing chain like the 5.7, took its place.
When should a Toyota Tundra’s timing belt be changed?
- 60 to 90 thousand miles. Whether or not a problem is apparent, a timing belt that is installed in an engine must be replaced at the service interval dictated by the vehicle’s manufacturer, which is normally between 60,000 and 90,000 miles. The precise service interval should be stated in your vehicle’s owner manual.
- Engine unexpectedly shuts down or won’t start. Timing belts may occasionally skip or break while the engine is operating.
- erratic engine performance. The timing belt’s contoured, strengthened teeth engage the crankshaft and camshaft gears. The belt may stretch or the teeth may wear out after many tens of thousands of kilometers, which will cause the belt to shift positions on the crankshaft or camshaft gears. The engine will likely operate poorly or not at all if the belt jumps.
- engine noise that is clanging or banging. The pistons and valves may clash in some engines if the timing belt has jumped, causing noise and damage. Interference engines are the name given to these engine types. The likelihood that a timing belt failure will result in engine damage will be reduced if your automobile has an interference engine by replacing the belt in accordance with the maintenance plan.
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?
While everyone is aware that a car’s timing belt needs to be replaced at suggested service intervals, what about the timing chain? What distinguishes a timing belt from a chain? A timing belt is a toothed belt that travels outside of the engine and is constructed of high-quality rubber. It is protected by a cover.
A bicycle chain-like timing chain is constructed of metal. 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.
Does the timing chain have a mechanical immunity? No, it is not, is the clear-cut response. Timing chain issues are prevalent, particularly in automobiles with heavy mileage.
A timing chain can wear out just like any other moving mechanical part within an engine. The engine oil lubricates a timing chain. The timing chain can wear down more quickly due to insufficient oil changes, low oil levels, or bad oil quality.
A chain tensioner maintains the correct tension on a timing chain. An oil pressure or spring-loaded device could be used to run a chain tensioner.
What Toyota Tundra mileage qualifies as high?
Really, the Tundra is a sure thing. Not only is it dependable, but several models can travel more than 200,000 miles, which is fairly amazing.
A timing belt’s lifespan is 200 000 miles.
That concludes our examination of the timing belt’s nature, operation, and significance. Can a timing belt travel more than 200 000 miles? Not at all. And to be honest, unless you have a junker that you don’t mind giving up, you really shouldn’t try this out in person. Expect severe engine damage if you continue to drive your automobile with a timing belt that is worn out, installed incorrectly, or otherwise flawed.
The cost of replacing your timing belt is by no means a cheap one. You’ll have to pay several hundred dollars, or in some cases nearly or more than a thousand. But this is little compared to the $2,000, $3,000, or even higher needed to rebuild a broken timing belt-related engine that has failed. Who would have thought that this tiny piece of rubber could fail and give you such heartache?
How much does a 2000 Toyota Tundra timing belt replacement cost?
Timing belt replacement price range for the Toyota Tundra. Timing belt replacement for a Toyota Tundra typically costs between $726 and $1,064. While parts range in price from $342 to $580, labor costs are predicted to be between $384 and $484.
What is the lifespan of a timing chain?
When should a timing chain be changed? Unless there is a specific issue, the timing chain typically needs to be replaced between 80,000 and 120,000 miles. In automobiles with higher mileage, chain problems are frequent.
How much does it cost to repair a timing chain?
Being proactive is a good thing because an engine that has a broken timing chain could suffer significant damage.
Timing chain replacement might cost between $600 and $800 to do it yourself or $1,600 to $1,800 to have a technician do it. Due to how difficult it is to replace this element, the price is exorbitant.
The parts for a DIY timing chain replacement will run you about $650. But this is a job that’s best left to mechanics with a lot of experience.
Fortunately, timing chains are built to endure the lifespan of the vehicle, unlike rubber timing belts, thus it is rare that you will need to have it changed. Watch out for these signs if you think your timing chain may be broken:
- Noisy timing chain
- Starting the car is challenging.
- While idling, the engine shakes or vibrates
- Engine has poor performance or is misfiring
- The check engine light is on.

When did timing belts stop being used?
It’s crucial to know whether your car has a timing chain, belt, or gears when thinking about engine maintenance. By transferring and half the crankshaft’s rotary motion and delivering it to one or more of the motor’s camshafts, one may control the ballet of the engine’s pistons and valve timing. Engineers employ timing gears, timing chains, or timing belts to accomplish this.
Timing Chain Vs. Timing Belt Basics
Overhead valve (OHV) engines have relied on timing gears or chains to turn the camshaft for many years. Many overhead cam (OHC) engines were powered by timing chains during the 1980s. Timing belts were particularly popular from the middle of the 1980s until the early 2000s, although timing chains are once again becoming more frequent.
It can be challenging to determine what kind of timing components exist in the engine of your car without disassembly. Timing chains and gears are typically inaccessible and covered in sealed metal for lubrication. Timing belts typically hidden behind open plastic coverings require protection rather than lubrication. Although this is a solid generalization, the easiest way to identify the timing components for your car is to look them up. Timing belt vs. chain can depend on the year, make, model, engine, transmission, and drive type. What makes that so?
Why Some Cars Use a Timing Chain Vs. a Timing Belt
Why use a timing chain in some engines instead of a timing belt or timing gear? Automakers and engine builders balance each’s advantages and disadvantages.
- Timing belts are lightweight and quiet, but they have a short lifespan. Since they are made of rubber, they deteriorate with time and need to be changed. Leaks in the coolant and oil hasten this degeneration. The majority of automakers advise timing belt replacement every 60,000 to 105,000 miles.
- Timing chains are more complicated and heavier than timing belts, but they last a lot longer. Actually, timing chains don’t need to be replaced very often unless there is an issue. Premature wear, stretching, and failure are avoided with routine oil changes.
- The heaviest and noisiest gears are the timing gears; some have compared the whining to that of a supercharger. Timing gears are durable, precise, and powerful, much like timing chains.
Because they were the only options at initially, automakers used timing chains and gears. Timing belts were introduced later and were discovered to be less noisy but troublesome. Numerous interference engines have been harmed by broken timing belts as a result of valve crash.
Interference designs enhance engine performance, power, fuel efficiency, and emissions to help engines breathe easier. To avoid early failure and valve crash, automakers have recently switched back to stronger, longer-lasting timing chains.
Timing Chain vs. Timing BeltIs One Better?
Due to their perfect timing and durability, timing gears are frequently used in high-compression engines, such as diesel engines. However, because of the way they sound, newer EFI systems can be fooled by vibrations from knock sensors. The shock-absorption capabilities of timing belts reduce high-revving engine harmonics, as in, say, NASCAR engines. Practically anyplace strength and quietness are sought, timing chains are used.
“It depends on what the engine is anticipated to do. Timing gears and chains were state-of-the-art for many years, but noisy and hefty. Timing belts met the desire for a quieter vehicle from drivers. Timing chains satisfy the needs of modern drivers who desire lifespan and the requirements of legislation who want efficiency. Engine builders balance an engine’s needs in applications that are specifically designed for them, like repair or racing.
