On the firewall, engine side, will be 2 hoses held onto the heater core pipes with clamps. Make sure the engine is cool, and get a bypass peice from your local Autozone, or what have you. Unscrew those clamps, and take the hoses off, then put the 2 hoses on the bypass pipe, and clamp back down. Do this only when the engine is cold. You will likely have to have the car up on jackstands, or wheel ramps. Its much easier to access the pipes from under the car. If you are tackling this job, you might just consider replacing the heater core while you are there. Its only about 30 mins more work, and is fairly easy. Best to grab a service manual for detailed instructions on this.
