Engine whine noise when still

[Lecko]

Afternoon

Just opened the bonnet on my 2002 172 and there is whine from the top of the engine, the engine is not running but the key has been turned so all the electrics are on, if you nudge it the sound changes if you know what I mean? I put my ear right next to it and it sounds like its next to where the 2 allen key screws are to remove the cover,

the only reason I noticed this because my fans have just stopped blowing today, so I was 'inspecting' fuses all seem ok, any ideas? fans wont work on any speed.

Fans will be your resistor pack mate.

There's a guide on how to fix it.

cheers, yeh the only reason I noticed the whine was because I haven't had the bonnet open for a while, cars running fine, belts all done in January, just never heard it before and panicking as you do!

I'll check out the guide, im not very technical but i'll give it a go

It'll be the throttle body! It's normal

It'll be the throttle body! It's normal

the whining noise?

 

[Ol’ Tarby]

Yeah the throttle body makes some strange noises when the ignition is turned on. Could always unplug it to make sure it is that
