Loud Noise on cold start

[CRG77]

Hi All,

I have noticed that my car is making a loud noise on start up but it only seems to do it on a cold start. Once the car has warmed up a bit the noise completely stops.

Anyone have any ideas what could be causing this? 

Thanks,

Connor

Try and discribe the noise

Hmm if I had to describe I would say it is a rattle sound. It sounds like maybe a pulley or a bearing. 

Hope that helps.
