The timing belt happens to be one of the constituents of the most capital of a car. But, in the case where we do not necessarily pay attention, the rupture of a belt will sometimes damage irreversible engine problems. Everyone knows that it's important to change the timing belt, on the Toyota Hilux 4 but also on any style of car. So as to fully understand the issues, we will go around the question about the timing belt: What is its role, why to change it, when to change it, and finally what to do to change it . Discover our specific article timing belt!
What is the purpose of a timing belt on a Toyota Hilux 4?
In order to master the function of the belt of this Toyota Hilux 4, you must understand what the famous distribution. In fact, distribution is the totality of mechanical components that governs the admission phase (the valves) of the air-fuel mixture, But also exhaust. The timing belt is a toothed belt, prompted through crankshaft pinion, which in turn encourages the pulley camshaft. Depending on the vehicle models, it can at the same time call the pulley of the injection pump but also the pulley of the water pump on most of the engines. Basically, it is the timing belt that gives the possibility to drive the pistons and other engine parts so synchronized.
Why change the timing belt on a Toyota Hilux 4?
Because of its material made of caoutchouc, the distribution belt wears out over time. Assuming you are riding quite well, the belt becomes much less malleable and less resistant. This characteristic becomes more and more noticeable if you are driving in urban areas, with incessant starts. If, on the contrary, you drive very little, the belt will sometimes deform staying day and night in an identical posture. If this belt loosens or comes off, it causes a engine stop instantaneous. In addition, due to the contraction, all of this can dent various components of the engine block. It is therefore essential to pay attention to it. We will suddenly look when it is essential to change it.
When to change the timing belt on a Toyota Hilux 4?
The downside with the belt is that it does not have a wear indicator. So it's complicated to see her condition, especially since she is hardly accessible in the engine. The best way to avoid engine failure is to follow the manufacturer's information. Nevertheless, it is sometimes wiser to trust the mechanics. It is often advisable to change them every 100 000 km, or every 5 years. Certain situations, such as coolant or oil leaks, can damage the belt prematurely.
How to change the timing belt on a Toyota Hilux 4?
Changing the timing belt on a Toyota Hilux 4 is not easy. Indeed, it is an essential part of the engine, therefore if it is not properly done, this will necessarily create major damage to the vehicle. Such a repair is therefore not recommended without the company of a garage owner. To change the timing belt, you must first buy the distribution kit full. Here are therefore the steps to follow in order to replace the famous belt:
- Make sure to loosen the tensioner pulley so that the belt is relaxed.
- Remove the timing belt.
- Undo all the rollers and the water pump.
- Secure the new water pump in place
- Place the rollers in their respective places
- Put the timing belt in place, respecting the marks
- Tighten the belt following the recommended tension using a tensiometer
- Operate the engine manually, which corresponds to 4 city turns
Conclusion
It is therefore essential to understand a few points before embarking on repairs. The belt happens to be a fundamental engine component, it is this one which makes it possible to synchronize various parts. Its natural degradation makes it important to change it often enough. If we let it take too long, it will sometimes damage the engine permanently. And finally, it is essential to have good mechanical skills before embarking on this type of repair. Voila, the key is in your pocket. Good road !
