The timing belt is one of the most important constituents of an automobile. However, if you do not pay too much attention, the rupture of a belt can lead to very serious engine problems. Everyone knows that it is important to replace this timing belt, on this Nissan Micra 4 just as much as on any vehicle model. To fully understand the subject, it is necessary to go around the question on the timing belt: What is its role, why replace it, when to replace it, and finally how to replace it. This is in fact a complete file specific to the timing belt!
What is the purpose of a timing belt on a Nissan Micra 4?
To understand the role of the belt of this Nissan Micra 4, it is necessary to know what is the famous distribution. In fact, distribution is the set of mechanical parts that governs 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 in turn drives the pulley camshaft. According to the styles of automobiles, this one can at the same time call the pulley of the injection pump but also the pulley of the water pump in almost all mechanics. Basically, it is the timing belt that will allow to drive the pistons and various parts of the engine block so synchronized.
Why change the timing belt on a Nissan Micra 4?
Because of its material made of caoutchouc, the distribution belt wears out over time. If you drive badly, the belt becomes much less malleable and less robust. This phenomenon is higher and higher if you drive in urban areas, with frequent starts. If, on the other hand, you do not drive much, the belt may deform staying in the same position all the time. If this belt breaks or comes out of its place, this creates a engine stop at once. In addition, with the tension, all of this could wreck precious parts of the engine. It is therefore essential to be cautious. We will suddenly see when it will be necessary to replace it.
When to change the timing belt on a Nissan Micra 4?
The downside to the belt is that it has no wear indicator. It is not easy to judge the state, especially since it is hardly accessible within the engine. The best way to avoid causing an engine break is to respect the manufacturer's instructions. However, it is sometimes wiser to trust garage owners. It is generally advisable to replace them every 100 000 km, or every 5 years. Some conditions, such as coolant or oil leaks, will damage the belt more quickly.
How to change the timing belt on a Nissan Micra 4?
Replacing the timing belt on a Nissan Micra 4 is not an easy task. Indeed, it is an essential part of the engine, that is why when it is not properly done, it will inevitably cause irreversible damage to the engine. Such repair is in fact not recommended without the company of a garage owner. In order to replace the timing belt, you must first obtain the distribution kit full. You will find below the steps to follow to replace this belt:
- Loosen the tensioner roller to loosen the belt.
- Release the timing belt.
- Disassemble all the roller rollers and the water pump.
- Install the new water pump
- Put the rollers in their respective locations
- Add the timing belt in place following the marks
- Tighten 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 certain factors before embarking on repairs. The belt is a essential vehicle component, it is this which will make it possible to synchronize some parts. Its natural wear makes it important to replace it rather often. If you really drag, the whole thing can irreversibly damage the vehicle. And finally, it is essential to have good mechanical skills to embark on this kind of repair. Voila, the key is in your pocket. Good road !
