For long-term use, a car must be well maintained. This inevitably involves frequent review sessions, which involve the regular replacement of several components after a given period of use. Among these components is the timing belt, the importance and functions of which require special monitoring and early change in the event of deterioration to avoid unwelcome disappointments.
What is the point of such a precaution?
Before thinking about changing your belt through reference platforms such as ad.fr, it is necessary to understand the importance of such a component, which implies a good knowledge of its precise role and its normal functioning. What is already known is that distribution is the mechanism by which the movement of the pistons compressing the mixture is synchronized with the movement of the valves that let this mixture in and out. This usually requires a timing belt, although some engines use a chain instead.
Generally, the belt is guided by one or more fixed rollers, and one or more tensioning rollers that allow its tension. The rollers are mounted on ball bearings, whose service life is linked to that of the belt. Tension is provided by a mechanical or hydraulic system. If the tensioner is mechanical, it is necessary to check its adjustment regularly.
Due to prolonged use or impact, the timing belt can break when it is not regularly checked and changed in time. This leads to a breakage of the distribution, synonymous with serious repercussions and damage to the engine of the machine. A considerable breakdown, which can lead to significant expenses, and especially a significant loss of time. Fortunately, there are signs and means of early detection of such a problem, and therefore of avoiding the occurrence of unfortunate disappointments.
What are the symptoms that should alert you?
Since the timing belt is well embedded, it is essential to remove its protections beforehand to have access to it. Ipso facto, unlike silent block, whose failure signs are quickly detectable (more information on this auto component on Gataka.fr), the main signs of belt wear (tooth shearing, cracking…) are not easily visible.
The only obvious symptom is the emission of a friction or squeal noise, which indicates repeated contact of the belt with a part of the engine, or a roller in poor condition. In any case, any abnormal noise should alert you, as it often indicates premature wear and tear.
What steps should be taken?
To avoid a failure due to a timing belt failure, the main preventive measure is to closely monitor the noise emitted by the machine in order to detect any symptoms. You will also need to perform regular checks on the belt at regular intervals to change it as soon as any anomalies appear. It is also advisable to replace the distribution kit systematically after a certain period of use, to reduce the risk of wear and tear as much as possible.
In addition, when replacing the water pump, it is also advisable to change it, since it tends to deteriorate in the same way as the rollers. Finally, the instructions in the manufacturer’s maintenance manual must be strictly observed and the replacement interval for the timing belt must not be exceeded. That’s why it’s worth investing in a good garage for your tune-ups!
