Thanks for read this and for the help.

What kind of noise is it? a screeching noise or a grinding noise? Is it when the fan clutch is egaged? you were not clear in your post.

if it starts making noise around 2000RPM I would think turbocharger. try to find the source of the noise with a short length of hose against your ear, and listen around for the sound.

Thanks guy´s for reply!

The Sound is similar to fan cluch went engaged!
Sounds like someting is puling air!!!!
My car doesn´t have a turbo.

May have a leak in the air intake system. Does the noise happen when driving, or can you manually raise the RPM to 2000 and hear it under the hood? Exhaust leaks can also make strange noises.

Ok.
I´m crusing at 100 km/h in 5th gear at 2200 rpm,It sounds like asking for the 6th gear (but I only have 5th gear)

Have you tested the fan clutch?

I'd also look at the air filter box, intake and exhaust connections and make certain there isn't a leak somewhere.

Is this a manual tranny or automatic?

The fan clutch is good! I will check the air filter, intake and the exaust!
It´s a manual tranny!
Could it be the vaccum pump, bearings???

Thanks guys!
