The timing belt is one of the most needed items of a car. However, if you really don't pay attention to it, a broken belt can damage irreversible engine malfunctions. Everyone has heard that it is necessary to replace this timing belt, on this volvo s90 or on any model of vehicle. In order to properly master the issues, we will go around the question concerning the timing belt: What is it for, why replace it, when to replace it, and finally what to do to replace it. Here is our little special timing belt file!
What is the purpose of a timing belt on a volvo s90?
In order to understand the action of the belt of your volvo s90, it is necessary to know what the distribution. In fact, distribution is the overall mechanical parts that control the admission phase (the valves) of the air-fuel mixture, But also exhaust. This timing belt is a toothed belt, carried through the crankshaft pinion, which then takes away the pulley camshaft. Depending on the different types of cars, it can at the same time call the pulley of the injection pump but also the pulley of the water pump on most engines. If we summarize, it is the timing belt that will allow to drive the pistons and various parts of the engine so synchronized.
Why change the timing belt on a volvo s90?
Due to its consistency in caoutchouc, the distribution belt will deteriorate over time. If you drive a lot, the belt becomes less flexible and less resistant. This characteristic is more and more important if you drive in the city, with repeated starts. If, on the other hand, you do not drive much, the belt may deform if it stays in a stable position all the time. If this belt breaks or comes out of its place, this triggers a engine stop at once. In addition, because of the tension, all of this can damage a certain number of system components. It is indeed essential to pay attention to it. We will now see when to replace it.
When to change the timing belt on a Volvo S90?
The problem with the belt is that it does not necessarily have a wear indicator. It is not easy to judge the state, especially since it happens to be difficult to access within the engine. The best way to avoid engine failure is to read the information from the manufacturer. However, it is often essential to trust the mechanics. It is frequently recommended to replace them every 100 000 km, or every 5 years. Several causes, such as coolant or oil leaks, can damage the belt more quickly.
How to change the timing belt on a volvo s90?
Changing the timing belt on your volvo s90 is not easy. Indeed, it is a capital element of the engine, in fact when it is not done properly, it will inevitably create very significant damage to the engine block. Such manipulation is therefore not recommended without the company of a garage owner. 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:
- Loosen the tensioner roller to loosen the belt.
- Remove the timing belt.
- Disassemble all the roller rollers and the water pump.
- Put the new water pump in its place
- Place the rollers in their respective locations
- Add the timing belt to its location, respecting the marks
- Tighten the belt respecting the recommended tension using a tensiometer
- Operate the engine manually, equivalent to 4 city revolutions
Conclusion
It therefore seems essential to know certain points before starting work. The belt is a capital element of the engine, this is the one that will synchronize several parts. Its inevitable wear makes it necessary to replace it relatively frequently. If left too late, it can irreversibly damage the engine. And finally, it is essential to have good mechanical skills to start this kind of tasks. Voila, the key is now in your pocket. Good road !
