water pump? (video/sound)

[Nooby]

wife parked the jeep last night, everything all good

this morning I went out to move the jeep over some in the garage since she parked a little to close to the van, as soon as I turned it on I heard this noise from inside
Ac/vent was off
2002 v6 3.7l

sounds like it was coming from the left side of the engine bay,
hard to hear on the video, hope it is enough

and help in figuring it out would be great

and if everyone thinks it is the water pump any recommendations for a new one, also what else should I replace when I am doing it, just did coolant a few months ago

I couldn't figure out how to show the video here?

sounded like the sound was from here when I put a metal breaker bar to may ear and against here at the base of the metal pipe coming up

I mean

it's been along day, and have been pretty sick

Ac compressor/cluch? I know the cluch is in the front of it

don't know why I put water pump, that is below it

if it is the bearings, will it do any other damage or can i use it till it breaks

ac is still cold

sounds like the idler pulley.

update, still does it weather ac on or off, also the clicking of the cluch is not as often as i remember
only 1x per min or so now

also after the jeep warmed up with ac on high for 10mins, the noise all but disapeared

Nooby, I'm strongly leaning towards Water Pump. Only because mine died recently and so its noises are fresh on my mind. Reach under the bottom bolt and see if you're weeping any coolant. It doesn't have to be much... like literally only a drop. Either way, I'm strongly leaning towards water pump.

If money isn't absolutely an object, you could swap the tensioner assembly/idler pulley and the water pump for probably around $100 (if you're doing the work yourself).

I can also tell you from experience that both jobs are very easy, even for the novice mechanic.

update:

well last weekend the noise increased greatly, as well as a burning smell, I didn't record the new noise but it sounded like this post

well anyway yesterday the ac clutch stopped engaging/no ac
but I had already called around and got esitmates for new dryer and compressor
took it in friday night, and it was fixed today, cost a pretty penny, but about 1/2 of what the dealer quoted me, but has 12k/1 year warrenty at least, they also put some of the leak die and told me to come back in few days for them to be sure they have every thing sealed up good
