It is never relaxing to hear a noise from your car you don’t know where from. So what if you identify a serpentine belt noise that lasts on your Toyota Yaris? It is extremely plausible that this is a unimportant problem, but before being sure, it is better to operate some checks. If this belt noise comes from your serpentine or driving belt, our team has written a post to support you finding and solving it. First, we will look at the serpentine belt noises on your Toyota Yaris and then we will take a look at the origins of these noises.serpentine-belt-noise-toyota-yaris

I encounter noises from serpentine belt Toyota Yaris

The best strategy to control the condition of your belts is to listen to your vehicle. Immediately after you find noises such as squealing or bells, you should take a closer look to verify their origin. The function of the serpentine belt or driving belt of your Toyota Yaris is to transfer the movement of the engine to the secondary components that it will supply with energy. Like steering, air conditioning, water pump. Its role is therefore important in the normal use of your vehicle. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the ability to drive different engine components at variable speeds.

I hear squealing noises on my serpentine belt Toyota Yaris

This kind of squealing belt noises on Toyota Yaris, which will often be acute, can in most cases appear when the engine is cold, or when the acceleration increases in intensity. . This kind of sound must be significant and it is normally quite simple to relate it with one of these belts. To verify, do not hesitate to open your bonnet, engine running cold and check the origin of this noise, the serpentine or driving belt being exposed, it should not be too complicated for you to identify a belt noise on your Toyota Yaris. The reason of this problem can be linked to the damper pulley, which functions as a damper to eliminate irregularities in the tension in the motor cycle and therefore in the energy transmission to the belt. This results in a loose belt that will jerk. However, you still have the opportunity that this phenomenon is annodine. As the serpentine belt of your Toyota Yaris is exposed, it may squeak due to excessive humidity due to weather conditions and it may stop with a change in conditions. Remember to verify the condition of your belt (crack, crack), if this is the case change it, otherwise simply tighten the belt.

I hear loud serpentine or driving belt noises Toyota Yaris

Just like squealing, a driving belt noise on your Toyota Yaris that sounds like a loud grinding sound can tell you a lot about its condition. It is therefore important that you look further and find the cause for this sound that can signal the end of your belt’s life. Like squealing noise, it can be identified in most cases when cold . It generally means a worn pulley whose streaks no longer allow it to be driven properly. Other alternatives, the dynamic belt tensioner or the disengageable pulley of the alternator may be at the origin of this problem. Make sure you verify first the serpentine/driving belt which in most cases is the reason of this problem, otherwise it will be necessary to change the tensioner or pulley.

I hear bearing noises on the serpentine belt of my Toyota Yaris

Finally, if in your case you discern a bearing belt noise on Toyota Yaris, it is plausible that it is linked to a serpentine belt that is too tight . Indeed, it is plausible that its size may be smaller than prescribed and cause the entire system to overvoltage, resulting in this whistling noise or slight rolling noise. The problem in this case is that the bearing bearings or the Damper pulley may fail . Remember, therefore, to stretch the belt to limit the risks or to swap it if it is too short. If after checking all thoses alternatives, you still identify a belt noises, read our article about timing belt noises on Toyota Yaris which could maybe help you.
