1. Issue Regarding The Car’s Alternator Of Altima

This is the most common issue when your Nissan Altima creates belt tensioner noise. Usually, a loud sound is heard if the problem is truly inside the alternator. The alternator mainly charges the vital components of the car. The alternator has also an impact on running into the car’s engine.

Instead of loud noise, another symptom is a sharp abrupt noise. Due to a problematic alternator, this sharp noise is heard. You have to find which one actually you are hearing.

The weather has an impact on such kinds of noises. This issue especially occurs when the weather is cold. Two sources can mainly be the culprits here.

3. Check The Bearing Of Your Nissan Altima 

The bearing is one of the most important issues. Though, you must have to check the bearing of your car for any sort of sound problems. A loud ticking sound is heard when the problem resides inside the bearing of your car. 

An alternator usually connects the belt and bearing, as a result when there is a problem occurring in the bearing then it can also affect the tensioner belt.

Solution: Changing the bearing is the main solution here. The bearing must have to be from a good company that produces compatible bearing for your Nissan Altima. If the bearing is not proper then you might not get rid of yourself from the loud noise of the Nissan Altima tensioner noise.

4. Serpentine Belt Can Also Be The Main Factor

When your bearing belt is connected to the serpentine belt too tightly then you can hear a smooth sharp sound. This sound is caused due the defect available inside your serpentine belt.

Solution: Well, before calling a technician, it is better you have a look first. Check, whether the bearing belt is too tight with the serpentine belt or not. If the answer is yes, then relax the belt a little. Check whether the problem is solved or not.
