Could also be bad radiator cap.

No anti freeze first. There was a recall for a bypass hose if that wasn't done it maybe the recurring nightmare

I think the reaccuring nightmare may refer to headgaskets which are common on the 3.8 Ford motors. First get some coolant in it, run it and see if there are leaks. Also check you oil, is it milkshake colored? or way overfull? post your results

Agree that it could be a likely head gasket leak. I encountered the problem after buying a new radiator and cap which was also needed. However with the new radiator adding additional pressure to the system, the head gasket then failed. A sure sign is white exhaust smoke and blowing moisture (anti freeze) out of the tailpipe. Head gasket problems are notorius in high mileage 3.8 engines.

Another potential problem could be a clogged cooling system. If the anti freeze is brownish rust and has the odor of burnt rubber you can be sure your system is sluggish. Be aware that flushing could enchance the problem and cause leaks depending how long the system has been sluggish. The heater core is the worst enemy in this situation being that it is small and they are difficult to flush successfully and the problem can re-occur requiring more than one flush attempt.

This didn't happen to my taurus, but to my 93 caravan. maybe they're close. the engine overheated like you said, and the heater stopped working (not fun in the dead of winter) long story short, the coolant hose to/from (can't remember which) the heater had burst, check that by having someone turn the car on and off while you look in there. hope that helps

your engine's thermostat, when it goes bad, the engine take so long to warm up and also the system don't blow hot air anymore

Probably the thermostat.

This can also be caused by allowing the coolant level to get so low that air gets into the system causing a "vapor lock" condition. Solution: get rid of the air by refilling the radiator. Unfortunately many of today's cars don't have filler caps on the radiator itself, just on the reservoir. Might be able to use the top radiator hose.

Where is the engine block heater on a 2001 Ford Taurus?

Yes there is, look under your front license plate, or where one would be if they aren't required in your state. Then go right, there should be a flip open cap covering a plug for the block heater there.That is if your vehicle has one installed - not all Taurus/Sables have an engine block heater.

If the heater core is not replaced can it cause damage?

If your heater core is LEAKING engine coolant so that your engine coolant level drops too low or the engine coolant is lost completely and causes your engine to overheat then your engine can be damaged beside the mess the leaking coolant makes inside your vehicle ( you might be able to just temporarily bypass the heater core so that no engine coolant is flowing through the heater core )

It would help to know what engine you had... if it's not a glider, the 2006 Volvos in North America were available with the Volvo D12 or D16 engine, the Cummins ISX or ISM engine, or the Caterpillar C11, C12, C13, C15, or C16 engine. Also, are the hoses blowing off of their connections, or are they just blowing out?

If Heater core is bad on a 1984 Mazda GLC will car overheat?

Not necessarily. It depends on what you mean by a bad heater core. The core will either be leaking or stopped up. If it is leaking, then it can cause the engine to overheat and the only fix is to replace it. A clogged or plugged heater core can sometimes be fixed by flushing it. You can also temporarily bypass the heater core until you can get it fixed. Just connect the inlet & outlet heater hoses together.
