Suzuki Ciaz - what is this noise?

[Walter]

I do spray WD40 once in awhile sa mga in between bearings. It works though for me.

That's not a good thing ...

WD40 has no place in a continuously moving part. It's a short-term lubricant meant to dislodge stuck parts (ie. screws, tools, etc). Apart from this product being able to displace water and moisture, it is also a good degreaser. Spraying WD40 on bearings will actually dissolve or remove whatever lubrication it has. It might work for a while, but once the very thin film of WD40 dries up, the bearing will end up in a worse condition than before.

Oh I'll take note of that. Thanks for the info.

I also think it's one of the bearings. Pulleys to check would be the idler pulley, alternator, water pump, and power steering pump (if not EPS).

When the A/C compressor runs, does the noise increase, decrease/disappear, or stays the same?

Sir oj, it only happens when all accessory including the AC are off. When AC and fan are on it doesn't squeak. When the engine or the alternator makes a charging sound, it doesn't squeak.

Pinacheck ko sa motech. hindi naman daw maluwag ung belt pero they didnt able to diagnose the issue kc that time wala ung noise. hindi ko pa alam na dapat patayin yung AC at fan para mag duplicate yung noise.
