Whining sound

[Djerms]

I'm hearing some whining sound whenever I depress the accelerator of my altis. I don't hear this sa iba naming altises. Considering na mine has a higher mileage, maybe its due to worn out parts na din.

Ano kaya kailangan ko palitan?

Note that I still hear it even if my radio is off.

Kung magpapalagay ako ng grounding kit, ano ba pros nito?

TIA

Bro,

Does the sound come from your speakers? If yes, your stereo and related components maybe grounded.

Otherwise, if the sound comes from your engine bay, there are a variety of areas where it may come from, pero try checking your belts baka it needs servicing.

MZ,
Just replaced the serpentine belt of my Altis. Sumasabay yung sound sa revving. As you rev higher, the louder and pitchier it gets. May mga bearings ba na dapat palitan. What components in the bay should I check?

Or could it also be that the serpentine belt is too tight?

TIA.
