Strange Noise

[soulman]

Hi,

There's a noise coming from the engine when it's running on my Seat Leon 1.6S(2002). It sounds similar to a worn fan belt. But, my local Skoda dealer Parkside in Bolton say the fan belt is ok. Could anyone help please?

when you turn ignition on do you hear it go ,, ggrrrrrr like a grinding sound? or like a stiff belt ? i have the same problem if so . my car does it when cold , once warm is fine. i changed my belts and pumps ect 12 month ago and all still good nick of course.

I don't really know a great deal about motors, but i think i have the same problem... when I turn it on something goes ggrrrrrr as you so adequately put it but when its sat at idle it also makes a whistling noise, like a squeeky belt... a friend of mine suggested fan belt needs tightening? does this sound the same as yours? and if so what did you do? thanks

Id get the aux belt swapped. Only cheap. Is it just sat at idle or moving you hear it?

 

[James93]

Both, but its not noticeably noisier when I rev. I can also hear it more after its been raining or if the car is wet?

I had the same issue with my evo 5.... Turned out the belt was in contact with the metal of the pulley.... Gets worse when wet and can hear it over engine noise? And gets louder as you pick up speed?

 

[James93]

Yea that sounds right... how did you fix that?

 

[youngyWHU]

unfortunately i had to replace the pulley, belt was fine as i got to it pretty quick. but it worth checking that too.... it only gets worse when the snow comes ;-)

 

[James93]

Right i'd better get it checked out, expensive?

A new pulley fitted set me back £200 roughly. On my last car.

 

[James93]

Alright ill look into it, cheers

mine just makes a funny sound when i first turn engine on and its cold. seems to be coming from drivers side. i had all belts changed 1 year ago approx 8k miles ago. have they done a crap job?

Could it be the starter motor overrunning?
