The timing belt is one of the most capital elements of a car. However, if we do not necessarily pay attention to it, the rupture of a belt will sometimes damage irreversible engine malfunctions. Everyone has heard that this timing belt needs to be changed, on a Toyota Supra Mkiii just as much as on any model of automobile. So, if you want to know the issues well, we will take a look at the question on the timing belt: What is it for, why to change it, when to change it, and finally how to change it. You will therefore find our exclusive timing belt article below!
What is the purpose of a timing belt on a Toyota Supra Mkiii?
So, if you want to know the function of the belt of this Toyota Supra Mkiii, you must know what the famous distribution. In fact, distribution is the overall mechanical components that govern the admission phase (the valves) of the air-fuel mixture and exhaust. This timing belt is a toothed belt, driven through the crankshaft pinion, which subsequently prompts the pulley camshaft. Depending on the styles of cars, it can at the same time call the pulley of the injection pump and the pulley of the water pump in most of the engines. To put it simply, it is the timing belt that gives the possibility to turn the pistons and various parts of the engine block so synchronized.
Why change the timing belt on a Toyota Supra Mkiii?
Thanks to its consistency in caoutchouc, the distribution belt wears out over time. If you drive a lot, the walking belt becomes much less malleable and less enduring. This phenomenon is more and more high if you drive intramural, with incessant starts. If it happens that, on the other hand, you drive little, the belt will sometimes deform if it remains day and night in an identical posture. If a belt breaks or becomes loose, it causes a engine stop at once. Also, due to the contraction, it may damage some parts of the system. It is therefore essential to pay attention to it. We will now see when to change it.
When to change the timing belt on a Toyota Supra Mkiii?
The problem with the belt is that it does not have a wear indicator. It is not easy to assess its wear, especially since it happens to be hardly accessible within the engine. The easiest way not to break the engine is to read the manufacturer's instructions. However, it is often wiser to trust the mechanics. It is still a good idea to change them every 100 000 km, or every 5 years. Several conditions, such as coolant or oil leaks, can damage the belt more quickly.
How to change the timing belt on a Toyota Supra Mkiii?
Replacing the timing belt on a Toyota Supra Mkiii is not easy. Indeed, it is an essential part of the engine, which is why when it is not properly accomplished, it will necessarily induce major damage to the engine block. Such an action is therefore not recommended without the presence of a mechanic. To change the timing belt, you will first need to buy the distribution kit whole. Consequently, you will find below the steps to follow in order to replace your belt:
- Loosen the tensioner pulley if you want to loosen the belt.
- Release the timing belt.
- Remove all the rollers and the water pump.
- Install the new water pump
- Place the rollers in their original location
- Add the timing belt in place following the marks
- Tension the belt respecting the recommended tension using a tensiometer
- Operate the engine manually, which corresponds to 4 city turns
Conclusion
It is therefore essential to know a few factors before committing to repairs. The belt is a capital component of the vehicle, it is she who will provide the means to synchronize various parts. Its natural degradation means that it must be changed relatively often. If ever we let it take too long, the whole thing will sometimes damage the vehicle irreversibly. And finally, it is essential to have good mechanical skills to engage in this type of repair. That's it, the key is now in your hands. Good road !
