Belt Squeeking!

Hey guys here i am with another noob question…

so my car makes a horible squeeking sounds when i first start it up… doesnt matter hot or cold… when i first start it up and i rev it a bit it squeeeeeeks!

also when i rev too high… at about 5-6k rpm it squeek squeeeeek squeeeeeeeeeeeks!!

i know its the belts… i just dont know which one it is… ive tried belt dressing and all other quick fixes but now i just want to replace them! i figure if im changing one i might as well change them all!

so what i need from you guys is the name of those belts and which is which… also maybe a part number from nissan? are they aftermarket belts that are maybe less prone to squeeking???

any help is appreciated! Thanks!

Could just be loose.

Check the tension on the belts and check for wear.

If the looked cracked or if you can easily deflect them, either adjust or change.

Make sure you don’t over tighten them as well.
