Without knowing your car specifically I can suggest the generic way to do it. Locate the two heater hoses going into the firewall, probably on the passenger side. They're the ones that get hot and are about an inch + in diameter. Disconnect. Measure the inside diameter of the hose and purchase a short piece of galvanized or copper pipe (6 inches) at Home Depot. Connect both ends of the hoses to the pipe to form a loop. Secure the hoses so they don't land some place that would cause a problem.
I had this problem on an 85 Tbird. I had heard about a product called Bars Leak and tried it. It worked. No leaks and I kept my heater. You should be able to find it at any parts place at less than $10. Ground black pepper also has worked for me.

Drain the Coolant system low enough that coolant don't drain from the hose when you loosen the hose clamps.Make sure the system is cold and no pressure on the system. Slowly remove the Rad cap.. You can go to the dealer and buy the factory hose or to a auto parts suppler and buy the right length and size usually 5/8 or 3/4 (Cheaper)

After the car warms up feel the heater hoses that go into the fire wall from the motor both should be warm if only one is warm and the other is cool the heat valve that opens the flow of antifreeze to the heater core is not functioning locate the valve (either under dash in passenger compartment or in the egine compartment) it has a vacuum line going to it and it should have vacuum when the heat is on if not replace the vacuum line or valve itself. Back flush heater core and also be sure the level of antifreeze is up to the top low antifreeze will cause no heat to occur.
