You will have to pin point that over heating. If you fluid level has not change you lincoln is not losing coolant. Means you would have air in your coolant lines or you have a bad water pump. There are 2 bleeder valves on the coolant lines depending which lincoln you have. Since yours is a 02 it still has the hydro fan, do you have the v8 or v6? If you have the v6 there is a bleeder valve at the front of the motor center of it also, back and under the intake tubing. Fill the coolant high as you can get it with the bleeder valve open as you fill the coolant box coolant will start coming out of the bleeder valve when it does that means that it is full. Close the valve back and fill the coolant box to its highest level. Alright now make sure that's the problem before dumping money into this car trust me its a expensive car. Well now for the heat it could be your DCCV, heater core, or you also have air in the heater lines. Which there is a bleeder line for that also. Its located near the coolant box.

As doing that need to open your heater bleed valve, after opening that you will need a partner or you could use the throttle cable. Hold the throttle at least 2500 RPM's and as water starts a steady stream of coolant out of it, you have cleared the air. Try these things first before dumping money.
