Default Could engine noise be the water pump? Video

We just picked up a 2003 GX470 and I love it except for the engine noise. My husband thinks it could be the water pump but wanted you input before buying it. There is a kit with the water pump, timing belt tensioner and pullies AC Delco, first off I'm wondering if you all agree this is most likely the problem and also what is OEM brand when it comes to Lexus, this is our first Lexus vehicle. Any help is appreciated! I was only able to attach 1 video but you will hear the noise in the audio, my file size was too big
P.S.(he took the fan off already to make sure it wasn't the fan). Thanks!

That sounds like the bearings are shot in that pump--no way that is normal sound

Thank you for taking the time to listen to it Booyah! Yesterday I went ahead and ordered an Aisin water pump and timing belt kit, so hopefully that fixes it. We will know this weekend, fingers crossed.
