It is never relaxing to discover a noise from your car you don’t know where from. Thus what if you discover a serpentine belt noise that lasts on your Toyota Hilux? It is extremely plausible that this is a minor trouble, but before being sure, it is better to execute 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.

I experience noises from serpentine belt Toyota Hilux
The best technique to check the condition of your belts is to listen to your car. Immediately after you recognise sounds such as squealing or bells, you should take a closer look to check their origin. The function of the serpentine belt or driving belt of your Toyota Hilux is to transfer the movement of the engine to the secondary elements that it will supply with energy. Like steering, air conditioning, water pump. Its role is therefore essential in the normal general performance of your car. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the capacity to drive distinctive engine elements at variable speeds.
I discover squealing noises on my serpentine belt Toyota Hilux
This sort of squealing belt noises on Toyota Hilux, which will often be acute, can usually occur when the engine is cold, or when the acceleration increases in intensity. . This sort of noise must be heavy and it is often quite simple to link it with one of these belts. To check, do not hesitate to open your bonnet, engine running cold and check the origin of this noise, the serpentine or driving belt being accessible, it should not be too difficult for you to point a belt noise on your Toyota Hilux. The cause of this trouble can be related to the damper pulley, which works as a damper to eradicate 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 an opportunity that this event is annodine. As the serpentine belt of your Toyota Hilux is exposed, it may squeak due to excessive humidity due to weather conditions and it may stop with a change in conditions. Keep in mind to check the condition of your belt (crack, crack), if this is the case replace it, otherwise simply tighten the belt.
I discover loud serpentine or driving belt noises Toyota Hilux

Other possibilities, the dynamic belt tensioner or the disengageable pulley of the alternator may be at the origin of this trouble. Remember to check first the serpentine/driving belt which in most cases is the cause of this trouble, otherwise it will be necessary to replace the tensioner or pulley.
I discover bearing noises on the serpentine belt of my Toyota Hilux
Finally, if in your case you identify a bearing belt noise on Toyota Hilux, it is plausible that it is related to a serpentine belt that is too tight . Indeed, it is plausible that its size may be smaller than suggested 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 possibilities, you still notice a belt noises, read our article about timing belt noises on Toyota Hilux which could maybe help you.
