Hello everyone i recently purchased g35 sedan and im getting this really loud annoying squeakin sound from the pulley area. It only does it when its really cold outside between 1k-2.5k rpm, but goes away once the car warms up. Anyone know what it is because its really irritating the hell out of me.
Any help is appreciated.

no big deal, belts need to be tightened

This is the coupe section BTW
