Instead of employing various belts in order to power up every single device at the same time, the serpentine belt of your Infiniti is used to drive several car components such as the alternator, A/C compressor, and PS pump. Known to be tough, the Infiniti serpentine belt can last for a long time, even about 150,000 miles with no routine service required. Though the poly-v belt can outlast several V-belts, it is meant to go wrong over the years, specially when subjected to too much pressure and heat under the hood.

The squeal you heard may possibly be caused by a maxed-out tensioner or even an out-of-line pulley, for that reason, you'd better be absolutely sure—figure out exactly where the noise is from right before you replace the serpentine belt of your Infiniti . A defective Infiniti serpentine belt will likely have splits or possibly uneven patches on its grooves or cords. The serpentine belt will not easily cease operating as soon as the belt starts squealing or cracks-however, you have to inspect this belt and get a dependable OE replacement for your Infiniti if necessary.
