The timing belt is one of most needed items of a car. However, if we do not pay too much attention, the rupture of a belt will sometimes cause irreversible engine problems. Everyone has heard that it is necessary to replace this timing belt, on this Toyota Highlander 2 or on any car model. In order to properly understand the subject, we will go over the question concerning the timing belt: What is it for, why replace it, when to replace it, and finally how to replace it. Discover our exclusive timing belt article!
What is the purpose of a timing belt on a Toyota Highlander 2?
In order to understand the role of the belt of any Toyota Highlander 2, it is necessary to master what a distribution. In practice, the distribution, it is the entirety of the mechanical components which directs the admission phase (the valves) of the air-fuel mixture, But also exhaust. The timing belt is a toothed belt, prompted by crankshaft pinion, which in turn carries the pulley camshaft. Depending on the car models, it may also call the pulley of the injection pump and the pulley of the water pump on most systems. Basically, it is the timing belt that will allow to drive the pistons and other engine parts so synchronized.
Why change the timing belt on a Toyota Highlander 2?
Because of its material in caoutchouc, the distribution belt will wear out over time. If you drive badly, the belt becomes much less flexible and much less resistant. This phenomenon is more and more noticeable if you live in the city, with repeated starts. If it happens that on the contrary you drive little, the belt will sometimes become deform if it remains day and night in the same position. When this belt breaks or leaves its location, it triggers a engine stop immediate. Also, because of the contraction, all of this can damage a number of engine components. It is indeed essential to be careful. We will now see when you need to replace it.
When to change the timing belt on a Toyota Highlander 2?
The problem with the belt is that it has no wear indicator. It is therefore complicated to judge its state, especially since it happens to be difficult to access in your engine. The best way to avoid causing a break in the engine block is to follow the manufacturer's instructions. However, it is sometimes important to trust the mechanics. It is usually a good idea to replace them every 100 000 km, or every 5 years. Several situations, such as coolant or oil leaks, can damage the belt prematurely.
How to change the timing belt on a Toyota Highlander 2?
Changing the timing belt on a Toyota Highlander 2 is not an easy task. Certainly, it is an essential element of the engine block, so when it is not properly accomplished, it will inevitably cause very significant damage to the engine.

- Tension the belt respecting the recommended tension using a blood pressure monitor
- Operate the engine block manually, which is equivalent to 4 city turns
Conclusion
It is essential to master certain factors before starting repairs. The belt is a fundamental component of the engine block, it is this which will give the means to synchronize some parts. Its inevitable deterioration makes it necessary to replace it quite often. If we delay excessively, the whole thing will sometimes damage the engine block irreversibly. Finally, it seems essential to have good mechanical skills to be able to start these repairs. It's done, the key is in your pocket. Good road !
