If your Mercury Mariner generates a loud noise when you accelerate, it is quite plausible that the alternator belt is the reason of your trouble. You will need to determine if this noise takes place abruptly and if it can stop as it started. The alternator belt is a wearing part that is employed to bring power to the secondary components of your Mercury Mariner’s engine and although it is less crucial than the timing belt it can generate engine damage if it fails. This noise may be a indicator of a slackened belt, in which case the tensioner roller or its wear and tear may be at fault. In any case, examine the condition of your belt and its tension. If it causes this acceleration noise on Mercury Mariner, go to your mechanic.
