First look for the highest place you can see the coolant. Many engines have a core plug at the rear of the engine that is only accessible once the transmission is removed. It is more common to have a leaking heater hose. The clue to the corroded core plug is the top of the engine will be dry. The coolant will be leaking out of the weep hole at the bottom/front of the transmission.

Also, look on the passenger side of the firewall, under the hood, for a four inch long rubber hose with a ninety degree bend in it, hanging down. Those are only on cars that came from the factory with air conditioning. If coolant is dripping from that hose, the heater core is leaking.

The issue now is the engine overheating because it is low on coolant, or is the coolant being pushed out because the engine is overheating? Most of the time an overheating problem causes coolant to be spit out of the reservoir, which is near the front of the car. The coolant will spray all over. If you are only seeing the coolant in one area, near the back of the engine, it is much, more likely you have a leak, and repairing that will solve the overheating. A pressure test will usually allow you to locate the source of the leak.
