hi,i am hearing a sheriking sound (from a pulley or something) when i start up my car specially after rain and if i put my foot on gas it goes away . seems like its from engine at passenger side in middle of engine. car is 07 tl 101,000 km

 

I had the same noise i replaced the alternator belt and since then it has not been a issue to me

 

thx,how much does it usually costs?
