Default So I think I diagnosed my problem as the WP

Of course I am pretty new to this and don't trust myself.

Symptoms include loss of coolant, overheating after extending periods of time due to the loss of coolant. Just replaced thermostat, water pump temp sensor, so those are assumed to be good.

I can see the coolant loss. It doesn't do it when the car has not been run, but once it begins to warm up some, it begins to drip. The drip travels though, so it is hard to tell where it is coming from. It is a steady drip. I cannot reach around the back to feel or see the weep hole, however, I can tell that the drip is rolling down off other parts. Basically, it looks like it rolls down part of the water pump and then down what looks like another bracket or something, near the PS/Tensioner pulley.

I can fill it back up, but of course, it keeps losing coolant the way I just described.

I have a bad water pump?

It is very likely that the support bearings and seals in the water pump are taking a dump. Coolant will begin to leak past them and drip out of the weep hole (located directly under the water pump).

Time for a new pump (or an electric one...)!

Sucks, because I replaced it 12000-15000 miles ago. That's what I get for buying cheap China junk, eh?

Depends on how hard the wiring is. Also, will I have to get a new housing since this one leaks, or would I just use a freeze plug. I read about how to install one once or twice but I forgot.

You can reuse your old housing. The EWP kits include a freeze plug that you use to block off the back of the pump. Wiring is pretty simple - just a typical switched 12V+ relay setup. You can pick up a plug-and-play harness from a few vendors of the site.

Wiring is very basic. There are threads about it everywhere you can search. If you want to see if it is the weep hole on the water pump just jack the front end up (use jackstands!) and you have a straight eyeball shot at it from underneath. You can tell either by seeing coolant or a dark stain around the weep hole and housing.
