[00:00:00]A lot of drivers see cooling around a water pump and think maybe a hose is leaking or something came loose.

[00:00:07]But this specific area right here is called the weep hole.

[00:00:12]The weep hole is intentionally built into the pump. Its job is to let cooling escape once internal seals inside the water pump starts failing.

[00:00:21]That leak is basically the pump telling you, "I'm failing." Once cooling starts coming out of that hole, replacement is usually needed because the internal seals have already failed.
