The timing belt happens to be one of the most essential of a car. However, if you do not necessarily pay attention to it, the rupture of a belt can induce irreversible engine malfunctions. Everyone knows that it is important to replace the timing belt, on this Smart Fortwo 3 but also on any type of vehicle. In order to fully understand the subject, it is necessary to go around the question concerning the timing belt: What is its role, for what reasons to replace it, when to replace it, and finally what to do for it. replace. You will find our small special timing belt file below!
What is the purpose of a timing belt on a Smart Fortwo 3?
In order to understand the function of the belt of any Smart Fortwo 3, you will have to understand what the distribution. In practice, distribution is the set of mechanical components that directs the admission phase (the valves) of the air-fuel mixture and exhaust. The timing belt is a toothed belt, carried through the crankshaft pinion, which then takes away the pulley camshaft. Depending on the different types of vehicles, it can also call the pulley of the injection pump but also the pulley of the water pump in almost all mechanics. If we summarize, it is the timing belt that allows to drive the pistons and other engine parts so synchronized.
Why change the timing belt on a Smart Fortwo 3?
Thanks to its material caoutchouc, the distribution belt wears out over time. If you drive a lot, the belt will become much less malleable and less robust. This characteristic becomes more and more noticeable if you are driving in town, with repeated starts. If, on the other hand, you do not drive much, the belt may deform staying in a stable position all the time. The moment a belt loosens or takes off, it creates a engine stop immediate. In addition, with the tension, all this can damage various parts of the engine block. It is therefore essential to pay attention to it. We will now see when you will need to replace it.
When to change the timing belt on a Smart Fortwo 3?
The problem with the belt is that it does not have a wear indicator. It is not easy to judge the state of it, especially since it happens to be difficult to access in your engine. The easiest way not to create an engine block breakage is to follow the manufacturer's information. However, it is often useful to trust the mechanics. It remains regularly recommended to replace them every 100 000 kilometers, or even every 5 years. Some causes, such as coolant or oil leaks, will deteriorate the belt faster.
How to change the timing belt on a Smart Fortwo 3?
Replacing the timing belt on your Smart Fortwo 3 is not easy. Certainly, this is a vital part of the engine block, so when not done perfectly, it will inevitably create very significant damage to the vehicle. This action is in fact not recommended without the company of a garage owner. In order to replace the timing belt, you will first need to purchase the distribution kit whole. Here are therefore the steps to follow to change your belt:
- Make sure to loosen the tensioner pulley if you want to loosen the belt.
- Remove the timing belt.
- Undo all the rollers and the water pump.
- Replace the new water pump in its place
- Return the rollers to their respective locations
- Add the timing belt to its location following the marks
- Tension the belt respecting the recommended tension thanks to a blood pressure monitor
- Operate the engine block manually, which is equivalent to 4 city turns
Conclusion
It is therefore essential to understand a few points before starting repairs. The belt happens to be a essential element of the engine block, it is she who will provide the means to synchronize certain parts. Its inevitable degradation makes it important to replace it relatively frequently. If you leave too much lying around, it can damage the engine block irreversibly. And finally, it is essential to have very good mechanical skills to start these practices. It's done, the key is in your hands. Good road !
