Sound in engine bay

[unmarked]

I have 07 altis AT at 83k kms. Nakaka rinig ako ng mejo high pitched sound pag cold start duda ko ung drive belt or serpentine belt. Pero nawawala ung tunog pag mejo uminit na makina. Parang umiikot na sound.

I dont think i encounter any trouble sa alternator, no symptoms of fault sa electricals. Kahit patay ang AC meron din nung tunog, so abswelto ung compressor ko tama? Pinalitan kasi ng surplus last year yun.

Stock na serpentime pa din naka kabit. Is that it?

Thanks I will, just want to make sure na belt talaga. How about the pulleys? Pwedeng source din ng trouble un kung misaligned or may movement side to side?

Yes when you have checked the belts it's also included sa pulleys. Usually pag pulley d nawawala ingay. Malalaman nyo po pag nabuksan na sir.

pag screeching - belts
pag squeaking - pulleys

better have that checked na din. pero at your symptoms, it has to be the belt.

You've all been very helpful. I will try the water spray method napanuod ko sa youtube from belt manufacturers for some diy diagnosing. Babalitaan ko kayo soon. Thanks again

its only a temporary solution, imho, but sooner or later, the sound will go back (assuming its the belt).
only solution is to replace the belt.

I understand sir, said diy diagnosing and not fixing. They said if the sound stops after spraying water, its either the belt or a misaligned pulley.

If it gets louder after spraying, it might be caused by incorrect tension.
