Technical Fiat Croma startup noise

[jekson85]

Hey guys

I am a member since quite some time but i never wrote anything, i have a Croma from 2008 and recently i had few problem with a strange noise at startup that seems stronger near to the timing belt.

After 30min if driving when the engine warms up the noise it's barely noticeable

I attached some video first at startup (with motor cover open)and then after 30min

of driving. Do you guys have an idea what it could be

When I first read your post I was going to suggest alternator belt, but having heard the noise now from cold if it was me I would first try from cold with alternator belt off, just in case it is something simple, then if noise still there I would try with cam belt cover off if possible and if nothing obviously wrong, try using a stethoscope if you have one or I have often used a long screwdriver to "safely" position near moving parts to trace a noise.
I emphasise "safely" as you don't want the screwdriver to catch something moving and ram the handle through your ear

Check the crankshaft pulley.

The problem was solved few months ago and it was actually the crankshaft pulley. I had to replace it already several time, within a timespan of two years.It seems a common problem on the fiat Croma

Check the crankshaft pulley.

What make pully / damper did you fit? I've used Gates on two cars and they didn't need replacing again.

Honestly I don't know the producer. The mechanic installed the part
