I have a leak behind the idler pulley and below the alternator. I changed the water pump no leaks around it. Please help. In the picture you can see the last of the drip. It pours out from there.

Hard to tell for sure, could be the thermostat housing or a hose leak. Check the engine oil for coolant to make sure it isn't a timing cover leak.

Hey Toby,

Can you give us a better shot of the leak maybe from under the car? Its tough to tell is it more oil or more coolant?

Best, Ken

I think the stuff that looks like oil is really copper based bars-leak. I know there is a core plug in the hole I marked but it looks like the leak might be above that.
