    wifes car, 89 buick lesabre, 3.8 engine, water is leaking out just below the water pump, seems to be comeing from a plug of some kind, hard to see because it is just below the pulley, anyone know what this might be and what it would take to fix, any help is much appreciated, thanks /forums/images/graemlins/mad.gif

    Sounds like it might be a freeze plug. You're going to have to pull everything out of the way so you can see for sure what it is. Providing it is a freeze plug, I usely drill a hole in the center and use a pick or pointed end punch to pop the old one out, then I like to use a piece of emory cloth to to clean the surfaces, and tap a new one in.

    I have a different opinion...it's the water pump itself. Water pumps are equipped with a throwout bearing, and when the bearing goes out, coolant will leak out of a little hole in the bottom of the water pump. This happens to every water pump. The bearing goes after many miles. It's not unusual. You need to get a new one, replace the old one, and you'll be running like new.
    It would be very odd to have a "freeze plug" on the front of the engine.

    Sounds to me like a water pump weep hole as well. There are many ways to tell if it is the w/p. If the pulley is tight but has play it, or there maybe a corroded trail the coolant left on the w/p.

    I second that, it's the weep hole, that usually means replace the pump with a new one.

    You might also check out the bypass hose(little hose between the pump and intake manifold) and fitting. The fitting on my Bonniville with a 3.8L was made out of plastic. It cracked and leaked similar to the way you describe.
    GM makes a upgraded metal fitting to replace the POS plastic one. The guy at the parts counter told me the plastic ones break all the time.
