What are the signs of leaking water pump ?

[Explorer_PL]

With the cold weather that hit the East Coast, I noticed small puddles of antifreeze under my Ex. It looks like it's located right under the center of the engine. I replaced the radiator 2 years ago (42k miles ago) along with the hoses, and back then the leak was in the front of the truck. I need to raise and take a better look where it's coming from, but was there like a rule that water pump leaks when the engine is NOT running, and not when it is ?

Great, thanks.

Need to stick my head there from under and trace it better.

I'll update if I figure out something.

False alarm.

I jacked up the car, and look under. The dripping was from the upper connection of the lower radiator hose.
When I replaced the radiator 2 years ago, replacing the hoses was a project itself, especially the lower hose where it goes back the motor. Very tight and I probably did not torqued it properly, but it held for 2 years. I just retightened it and will see.


Also, I found the reason why my car was making that horrible knocking noise in the back - I thought my strut is broken, but it's just broken sway bar link - $ 17 from NAPA
