It is never enjoyable to listen to a noise from your car you don’t know where from. So what if you discover a serpentine belt noise that stays on your Subaru Crosstrek? It is very possible that this is a minimal problem, but before being sure, it is better to operate some verifications. 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 Subaru Crosstrek and then we will take a look at the origins of these sounds.
I encounter noises from serpentine belt Subaru Crosstrek
The best strategy to check the condition of your belts is to listen to your vehicle. As soon as you notice sounds such as squealing or bells, you should take a closer look to examine their source. The role of the serpentine belt or driving belt of your Subaru Crosstrek is to transmit the movement of the engine to the secondary parts that it will supply with energy. Like steering, air conditioning, water pump. Its role is therefore essential in the normal overall performance of your vehicle. The serpentine belt is said to be asynchronous, i.e. unlike the timing belt, it has the capacity to drive distinctive engine parts at variable speeds.
I listen to squealing noises on my serpentine belt Subaru Crosstrek
This kind of squealing belt noises on Subaru Crosstrek, which will often be acute, can generally appear when the engine is cold, or when the acceleration increases in intensity. . This kind of noise must be heavy and it is often quite simple to connect it with one of these belts. To examine, do not hesitate to open your bonnet, engine running cold and check the source of this noise, the serpentine or driving belt being exposed, it should not be too complicated for you to spot a belt noise on your Subaru Crosstrek. The cause of this problem can be in connection with the damper pulley, which works as a damper to get rid of 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 a chance that this event is annodine. As the serpentine belt of your Subaru Crosstrek is exposed, it may squeak due to excessive humidity due to weather conditions and it may end with a change in conditions.

It generally means a worn pulley whose streaks no longer allow it to be driven correctly. Other possibilities, the dynamic belt tensioner or the disengageable pulley of the alternator may be at the source of this problem. Don’t forget to examine first the serpentine/driving belt which in most cases is the cause of this problem, otherwise it will be necessary to swap the tensioner or pulley.
I listen to bearing noises on the serpentine belt of my Subaru Crosstrek
Finally, if in your case you distinguish a bearing belt noise on Subaru Crosstrek, it is possible that it is in connection with a serpentine belt that is too tight . Indeed, it is possible that its size may be smaller than recommended 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 change 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 Subaru Crosstrek which could maybe help you.
