It is never enjoyable to hear a noise from your car you don’t know where from. Then what if you detect a serpentine belt noise that remains on your Mercury Mariner? It is highly plausible that this is a minimal issue, but before being sure, it is better to conduct some investigations. 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 Mercury Mariner and then we will check out the origins of these sounds.serpentine-belt-noise-mercury-mariner

I feel noises from serpentine belt Mercury Mariner

The best strategy to check the condition of your belts is to listen to your vehicle. Immediately after you find sounds such as squealing or bells, you should take a closer look to examine their source. The task of the serpentine belt or driving belt of your Mercury Mariner is to transfer 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 critical in the normal 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 hear squealing noises on my serpentine belt Mercury Mariner

This kind of squealing belt noises on Mercury Mariner, which will often be acute, can generally occur when the engine is cold, or when the acceleration increases in intensity. . This kind of noise must be significant and it is often quite simple to relate 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 accessible, it should not be too difficult for you to spot a belt noise on your Mercury Mariner. The cause of this issue can be connected 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 possibility that this phenomenon is annodine. As the serpentine belt of your Mercury Mariner is exposed, it may squeak due to excessive humidity due to weather conditions and it may end with a change in conditions. Keep in mind to examine the condition of your belt (crack, crack), if this is the case replace it, otherwise simply tighten the belt.

I hear loud serpentine or driving belt noises Mercury Mariner

Just like squealing, a driving belt noise on your Mercury Mariner that sounds like a loud grinding sound can express a lot about its condition. It is therefore necessary 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 correctly. Other alternatives, the dynamic belt tensioner or the disengageable pulley of the alternator may be at the source of this issue. Make sure you examine first the serpentine/driving belt which in most cases is the cause of this issue, otherwise it will be necessary to replace the tensioner or pulley.

I hear bearing noises on the serpentine belt of my Mercury Mariner

Finally, if in your case you identify a bearing belt noise on Mercury Mariner, it is plausible that it is connected to a serpentine belt that is too tight . Indeed, it is plausible 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 swap it if it is too short. If after checking all thoses alternatives, you still notice a belt noises, read our article about timing belt noises on Mercury Mariner which could maybe help you.
