I JUST UPLOADED VIDEO TO SHOW NOISE PLEASE CHECK IT OUT
View My Video
put in a alternator today and as soon as i started it up there is now a weird noise from the drivers side top of the engine that comes and goes
i replaced everything the same as i took off
i did remove the coolant hose from the top of the engine so i could have more room..there was about 2 cups that spilled out of there and some went on belts etc...
could it have something to do with the intake ? since i dissasembled all the air box etc to get to alternator?
could the noise be air in the engine? its not like a rod knocking noise its almost like a chirp then gets louder... give it gas and it went away but at idle it was there..i only did this for a few seconds then turned the car off..tried about 3 diff times all same results...anybody have a idea?
thanks in advance
i included a video on top if that helps

Wipe the belts and pulleys clean ,your problem should disappear.
Does the noise in the video sound like a belt issue? Thanks
You forgot to pull out that raccoon's nest while you were in there, they're just pissed you found them, and maybe they're cold.
Seriously, clean the belts and pullies, grab some simple green or windex and clean till they shine.
If the noise persists, could also be bad bearings in your idler pulley; when you get the belt off, check each pulley for axial and radial play, up down left and right.
thanks man it had to of been the belt its good to go now!!! thanks for all your help
