Hey guys my 02 954 is making a whistling noise once the temp gets around 180 any ideas what it could be.....Thanks, m320

 

possibly a loose vacuum hose?

 

More info please, could be a normal sound, could be a exhaust leak. I need more info.....

 

Thanks guys ....It seems to start this sound once the engine starts to get warm....Most probably when the thermostat starts to open in the heat range....Seems like I have read somewhere about this problem before but can't find it anywhere.....Thanks, m320

 

Location of sound?

 

Sound seems to becoming from RH side under fuel tank....Thanks, m320

 

whats going on performance wise while the whistling is happening

 

Have not noticed any change in performance just the whistle sound.....Thanks, m320

 

Can you hear it with ear plugs in and helmet on? If not, then I don't sweat it.

 

It's probably just the fuel pump. Fill up the tank and see if the sound is less noticeable.
