Why does my fan belt on my truck come loose when it rains?

water is splashing on the belt, theres an adjuster bolt so you can tighten it, usually somewhere round the alternator on trucks

Loosen the bolt holding the generator and move it a 1/4" to 1/2" to tighten the belt a bit, then go find another puddle.
