Whirring sound and Radiator Fan Running

[Quiet]

Hi all,

I noticed today after about 250Km run. (Very Heavy footed) the radiator fan kept running after ignition off for about 2 min and there was a whirring sound for another 15-30 sec. It's my Mazda. 

Is it normal cos it has not done that before and non of my previous cars or my  Vezel has done that.

Thnx

maybe the engine was overheated, so the fan kicked in. I have seen it in volvos

Sounds normal. Not sure what the whirring sound is... could be something as simple as a worn bearing.

Sounds normal to me too except for whatever the whirring sound after the engine was switched off.

I saw in  some forums that the sound is due to injector self cleaning. I do not know what that is though.

i don't think it's a worn bearing cos it's clocked only 10,000Km

By heavy footed, did you mean RPMs between 4-5? (x1000)

This is worse than the guy who complained of smoke comming from a pipe at the back of his car,...

Really? How so?

 

@Quiet, You may want to refer your owner's manual with regard to the whirring sound. Is this whirring sound coming from the engine as well?

Not that much, It was 2-3.5

Oh well the manual says radiator fan working after ignition off is normal.  I can't find any info about the other sound. There are few posts in the net about the same sound I guess.

I ll ask agents next time I go there what that is.

sorry guys, not a vehicle expert ?

The vehice is being driven in a hot climate, I would not be fazed by it but just check the coolant level in the expansion tank.then move to further checks in-depth,...

p.S.  Most of our drivers don't look at the temp gauge even when the engine is steaming ,..!

While the fans running for longer is normal when the coolant has reached a certain temperature, the concern here is about a whirring sound which I think is perfectly okay to be concerned about, because sounds emitted before or after a vehicle is switched on/off is not really identical on every car.
