It happens from a cold start only. I will start the van, with no problem, and approximately 5 seconds after the van is running, I will hear a rather loud noise (sounds like it might be coming from the driver side under the hood) that sounds something like this (zzzzzzee) The noise only happens for about 2 seconds and then it goes away. The car dealer I took it to has no idea.

spray water on belt if noise dissipates it probably needs replacing along with tensioner.
