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 a 2008 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.

When should a Toyota Yaris’ timing belt be changed?
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.
What issues does the 2008 Toyota Yaris have?
The most prevalent problem with the 2008 Toyota Yaris was caused by body and paint issues. Many Yaris owners voiced their complaints over the clear finish and paint peeling off their cars.
One irritated motorist complained, “This summer, the clear finish started peeling and spot bubbling off. I spoke with Toyota yesterday, and they refused to fix the car because it was more than three years and 36,000 miles old. The door frames or back quarters have not yet been affected; this is only on the roof. When it is washed, it immediately peels off, despite the fact that it appears to be speckled or bubbling up more than just vanishing.
This is only one of the numerous remarks and accounts that highlight this serious issue. All of this is said without addressing the financial side of the problem. Drivers reported spending, on average, $1,500 to repair this problem. It’s understandable why this is the primary problem with the 2008 Toyota Yaris.
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.
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.
How frequently must timing chains be changed?
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.
What happens if a Toyota’s timing belt snaps?
An engine that is freewheeling will simply stop running if the timing belt fails. But interference engines are used in several other Toyota motors. In other words, the pistons take up the same amount of space in the cylinders as the open valves do.
Are Toyota Yaris vehicles dependable?
The Toyota Yaris has a 4.5 out of 5.0 reliability rating, which places it first among 21 subcompact automobiles. Its great ownership costs are reflected in the $333 average yearly repair cost. Major troubles with the Yaris are rare because of the low severity of repairs and average frequency of those problems.
