I have a 1992 Plymouth Sundance with 130000 miles. 4 cyl, 2.0L It has been well taken care of with regular maintenance between 3k to 5k intervals since I bought it with 58k. The car instantly overheats when turned on. The heat blows frigidly cold air. It has a thermostat that is ~5 months old. The car will shudder and shake and then cut out when left idling or when it over heats. It is not losing coolant, but the car smells like burning antifreeze when you lift the hood. It will also steam and or smoke that escapes from under the hood when you turn it on. 1.) What are the possible diagnoses? 2.) How much will it cost? (Chicago area) 3.) Is it worth spending the money on a rebuilt car that I've had since high school, or should I just give up and buy a newer car? The most common cause of simultaneous engine overheating and no heat from the heater is extremely low engine coolant level, in other words a large pocket of air in the system. In some cars it's fairly easy to get the air out, in others it's very tricky. If there's a leak causing coolant loss, that will also have to be addressed or the problem will recur/worsen. Check 1. Your Thermostat (70%) of the time it is your thermostat. 2. Check and see if your radiator is clogged (Also very common).

Another issue is if your car overheats during idle, then it could be the electric radiator fan.

It could, but I'd start by checking the timing. If it's off the car will overheat, and that's easy to adjust. Heater cores are a grade-A pain to replace because you have to take apart the dash to get to them.

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.
