it's been almost five years since i had my celica, and the problem that i am having with now is the noise that is coming from under my Hood
some where... I think that it might be my alternater, the bearins inside of it, but i also think it's the belt tensioner. i could be wrong... it gets really loud when its cold outside only. on warm days, the noise is gone... what can this be... give the some advice before i spend some big money at the shop.
