Water pump going out? what does it sound like

been noticing lately that when i first start the car up when its cold there is a bad clancking noise in the front end. You can feel the "knocking" through out the car, vibration in the blower bracket, upper intake, and you can feel it in the shifter.
I pinpointed where it is coming from and I beleive its coming from the water pump.
I removed the belt and started the car and the noise went away. Therefore I beleive it to be coming from here.
is this typically what a water pump sounds like when it goes out?
Whats a good replacement to keep my car cooler?
thanks
Dan

my water pump went out last week. it didn't make a whole lot of noise, but i could hear it a little when my car was at idle. the way that i knew it was going out was that fact that it was streaming out antifreeze from the two holes on the waterpump. i would get under the car and check that first to see if it is leaking antifreeze out.

Are those the "weep" holes? Someone was telling me that water pumps leak at weep holes before they go out. I haven't seen these holes before so I don't know.

I have no leaks at all to be honest.
However the sound appears to be coming directly from the water pump, as it doesnt make this sound when the belt is disconnected. I guess it would kinda make sense to be the water pump since it only makes this noise when the car is cold for the first minute?
What about a bearing in the pump itself?
Should the water pump pulley spin freely and easily? mine does w/o a problem in either direction.
just wondering

jordanpace,
yep you got it! Only when the car is cold and you first start it, but as soon as you drive it for like 20 seconds its gone. I narrowed the noise down to the waterpump area. if your remove the belt its gone, but when you put the belt back on it comes back. If you let the car sit and idle it will keep making the noise, but if you get in the car and back it up right away it will go away within 20-30 seconds, i guess as the rpms go up. Might be a sticking bearing or something.
I guess this has got to be what it is, as there is really nothing else around that area that could cause that sound

OK does this still sound like the water pump?

Now the car has a squeaking noise to it, sounds like a bird or something chirping under the hood. You can hear it at idle and its getting much louder. Its definetly louder than my supercharger, and its coming directly from the water pump area.
so is this what it is?
There is no coolant coming from anywhere however

That is probably what the cause is. They will usually leak when they go out though.

If you replace it, either get a new or remanufactured (rebuilt) Ford unit. And get one with a lifetime warranty. Make sure to get all of the gasket material off as well.

i got my car in may so i don't have any other winters to compare it to, but the other day i started to notice a little bit of a clank sound when i first start it for like 1-2 seconds. then it goes away for good. I replaced my water pump with a stewart a little less than a month ago. It was leaking out of the weep hole. Its a small hole in the bottom of the pump that looks like it should leak out of there on purpose. Anyway, I would like to know what that clank is. Any chance its not enough oil in the engine when its first started? I changed my oil about 2 weeks ago and never heard the sound before, but its definitely gotten colder since the oil change and I've been driving the car less as well. I did prime the oil filter first before putting it on and I get good oil pressure after its first started. somewhere in the neighborhood of 50-55 PSI.

When my pump went out on may car some years ago the clanking sound was the impleller hitting the pump housing. It was weeping a lot too. The bearings and seals just eventually go.

Possible Cause of problem

Check your belt tensioner. Often times if the tensioner is out as far as it will go, the front and back pieces will hit eachother where they cross and make a knocking noise as the belt tension varies. (you will see what i mean when you look at it.) This happened to me once and I couldn't figure out for the life of me where the noise was coming from untill i looked there. I figured that since this is close to the water pump, it may be the cause of this noise. Hope it helps.

God do I feel like an idiot!
I did the ole' screw driver trick of listening to hear where the noise was coming from. Well its coming from the tensioner. Everytime the tensioner moves it makes a knocking sound!
So would the tensioner cause a squealing noise at idle as well?
Where can I get a new stock tensioner for a reasonable price?
thanks
Dan

???

Usually when a water pump goes out it sounds like marbles...not like detonation marbles, but kind of like shaking ball bearings in your hands kind of sound.
