Grinding noise in engine bay

[Robinyip]

hi all,

 

just discovered a grinding noise this evening from e engine bay.

 

when i on the aircon lever to 1 or 2, there is no sound as the fan will not turn.

 

but once i on the a/c, the grinding noise from the fan will come.

 

anyone knows what is the fan for? radiator fan or condenser fan?

 

thanks alot.

abt 5 years..

 

if off no sound, on then the fan will run, the sound is from the fan grinding something.

Maybe something has got into e fan compartment n rubbing on e blades?

 

Seldom i hear fan motor spoil especially only 5 year car.

 

U can try to dismantle n remove whatever inside or send to ac ws to check.

Hi

 

Need help

There is this roaring sound from engine compartment when car move off from stationary sounded very rough.

Normally about 2000rpm onwards.

When ok highway which rpm is normally below 2000 there is not significant sound.

 

This roaring sound will sometimes disappear and it will be smooth like baby but most of time it is around.

 

Abit like modified exhaust sound but my car is stock.

Hi Folks,

I am hearing this noise from the engine bay.  Besides the sound from the belt, it seems to have this "kroc, kroc" sound in between too.

What is a likely problem? Compressor, bearing or belt jam?

My old Teana is parked in a multi-storey car park.

Should I drive another 10km to the workshop or should I call a tow vehicle? 

Thanks.  I am attaching 2 videos below.  Edit - Seems that the browser can only play the sound but can't show the video.

Sound like your serpentine belt is cracked ?? Maybe.

Inspect your belt.

Drive to workshop lor. 

If on the way break, battery charge will light up.  Time your watch, you have generally about 30 mins to reach your repair shop.  Watch temperature. Off Radio, Aircon - don't work but still need to turn off aircon if it is magnetic clutch, off headlight.

 

It happened to me once .......

Kroc Kroc sound seems like some broken parts inside the engine.... Hope it is not that serious!

hard to pin point ,  it could  be as simple as tensional pulley problem. If i were you I would drive it to a workshop,   but if you are afraid, spending $50 to $100 to buy a peace of mind to tow your car is  fine too.  just go on the middle to left lane and watch the instrument cluster for exceptions while driving.

If sound only appears when aircon is on, the likely compressor. Else like the rest said, tensioner or one of the bearings. 
If it’s a belt, it will squeak instead of this sound. 
try shining a torch in there to see if any of the pulley is wobbling.

Thanks folks.  Managed to get it fixed.  I have changed the alternator pulley.  Parts and labour  = $160.  

And also passed the vehicle inspection!
