YEah abe, I can't say anything that wasn't already said. It is your heater core and just like everyone else said, it's a pain IF you have A/C.

To re-route you hoses, standing in front of you car, open your hood (of course) and see the two hoses going into your firewall (at the back of the engine on the left side, going to the interior of the car). One comes from the water pump, the other from the lower intake. They hook directly onto the two prongs coming from the heater core (which, like I said b4, sticks out through the firewall).

Just remove the clamps on both ends of the hose that goes from the water pump to the heater core (at the firewall) and remove the entire hose. Next, on the remaining hose, remove the clamp on the end that is on the heater core, take off the hose on that end and clamp it to the water pump (where you just removed the other hose from). In addition, you should probably plug the 2 prongs sticking out from your firewall (the heater core prongs).

That's it. Should take 15 minutes, MAX.
