If this belt breaks, the alternator will stop working immediately, along with the water pump and, if you drive long enough, with it broken, the engine will overheat and you will blow the HG.

Good luck with your fix.

The belt looks fine, I've noticed with a multimeter that the battery is at 14 with the car on but when off it slowly starts to drain below 11.75 when off for couple hours( i have no amps, speakers etc completely stock) and the red battery symbol is lit, which i read in the manual means alternator problem.
