What's causing this noise??

Hi all,

Been experiencing a weird noise on my 06 Clio MK3 1.4.

Its been happening for a long time now and only seems to happen when the engine has been started from cold, once warm it goes away.

Let me know what you think!

Doesn't sound any different to a normal cold engine imo.

Can't u hear the 'swooshing' noise? It sounds like its coming from near the belt area but I'm not sure?

Can't you hear what I'm talking about? I can hear it clearly in the vid?

Could it be an airlock in the cooling system?

Could this be the case if it only happens when the engine is cold? does not happen when the engine is warm?

I was thinking it could be one of the pulleys or something, the noise seems to speed up as i press the accelerator?

Yeah when i had an airlock mine always used to make a swooshing noise on cold start up, and yeah it could be.. Its hard to tell from the video though mate, to check if its an airlock after a drive let the engine cool down for a little bit not so its cold but still warm and open up your coolant tank and if it releases alot of air then theres your answer but hmm difficult one!
