Timing chains or belts are present in Toyota Highlanders?
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 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.
When should the Toyota Highlander’s timing belt be replaced?
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.
Should timing chains be replaced?
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.

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.
How long does a Toyota Highlander timing belt last?
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.
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.
Which motors include timing chains?
The timing chain, which is found in the engine of the car, synchronizes the various components so they can operate together. It is constructed of metal links that function as a chain to transfer the crankshaft’s motions to the camshaft. This enables it to grasp onto the various wheels and gears.
Depending on the model of your car, the timing chain may be a single, double, or triple chain. A hydraulic tensioner is present to keep it tight.
Timing chain vs timing belt
As previously mentioned, the timing chain is utilized to coordinate the motion of some engine components. The timing belt and this are comparable. The timing belt’s ability to power the water pump on some automobile types may be the only distinction. Other than this, synchronizing the crankshaft, camshaft, pistons, and valves is essentially their shared responsibility.
Timing belt or chain: Which is better?
- The timing chain’s key strength is how durable it is. Due to its high strength, it should typically not need to be replaced and should last the whole life of the vehicle.
- A timing chain only needs to be checked every 125,000 miles of use. Otherwise, it requires no maintenance.
- The metal in the timing chain is resistant to temperature changes, in contrast to the rubber that makes up the timing belt.
- A timing chain weighs more than a belt, which increases fuel consumption (and the pollutants it causes), which over time reduces fuel efficiency. Additionally, its weight affects engine output.
- Timing belts are much quieter than running timing chains.
- It is typically only feasible to equip big cylinders due to its weight.
- It costs a lot more to buy than a timing belt would.
- Because the timing chain is constructed of metal links, engine oil must be used to lubricate it continually.
What cars have timing chains instead of 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:
- Corvette by Chevrolet
- Duster, Sandero, and Sandero Stepway from Dacia
- Skyactiv-G engine in Mazda
- Every SAAB has a turbocharged engine.
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.
How much does it cost to repair a timing chain?
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.
