Don't know anything about the 4WD version, but my '93 2WD has been outstanding! 184,000 on it, owned for eight years now with no problems to speak of. I would advise buying a good trans cooler if you plan to do much towing. Soon after puchase, had problems with trans fluid everywhere when I would push the van while towing my 2200 lb boat at interstate speed. Trans never acted up, just fluid covering the entire bottom of the van, even up the tailgate, and the front of the boat! Took it in to the shop who insisted the trans had failed, but I did not believe as it was working perfectly otherwise. Finially found someone who knew enough or was honest enough to help. As the fluid was obviously scorched, he related that as the fluid heated it had expanded out an atmospheric vent on the trans and messed itself. Flushed the trans, cooler, and lines, changed the filter and added a large trans cooler in front of the condensor, behind the existing external trans cooler. No more problem in eight years and 80,000 miles, never did rebuild the trans and still works great. Have since towed cars through Smoky mountains without issue! Mine is only a 3.0L with highway gears and no towing package. Occasionally the factory springs would sag a little under load, so I added air shocks (Monroe MaxAir, Advance Auto Parts) which helped a lot. Good luck!

I am a professional HVAC service tech. "Black Death" is a term someone coined to describe the after-effects of a catastrophic compressor failure. The metal particulate released into the refrigerant stream and oil when the compressor self-destructs is circulated into the system by the pressure that the compressor created before it died. The black residue gets into everything it can before the pressures equalize and stops wherever it is. This can sometimes be more severe than others, depending on how much pressure differential was up when it died, the higher the pressure, the more extensive the contamination. This is not exclusive to Aerostars or even Fords. Most compressor manufacturers or rebuilders of all brands will not honor their warranty unless precautions are taken to remove all contamination, for if not removed, it will take out your new compressor as well. They usually insist on flushing of all components, replacement of the flow control orifice, and the addition of an in-line filter, preferably in the liquid line ahead of the orifice. Your tech will have to assume the worst and flush and clean everything. Unfortunately, on vans with rear A/C, flushing the long lines and second evaporator is essentially like cleaning up two passenger car systems and is very time consuming, though $2000 for a compressor changeout and system cleanup seems abusive. Shop around, but stay away from the "cheap fix". A compressor swap may work for a while, but will soon fail if precautions aren't taken.
Insidentally, should you decide to repair, I suggest that you look a little deeper into why it failed in the first place. The Ford compressor of this vintage has a bad rep for failure, but my experience has shown them very dependable. My '93 has 184,000 miles on it, still running R12. The system has not been open since '98 when I replaced a leaking O ring. From what I've read from others, I surmise that inadequate air flow accross the condensor (in front of radiator) is more likely the problem. Low air flow results in increased head pressures that the compressor has to overcome and can significantly shorten it's life. Check to see that the cavity between the radiator and condensor is still sealed. Is the rubber seal between the radiator and crossmember still there? Is the gap between the radiator and condensor still seaked underneath? If these are missing, a trip to Home Depot or such for a window A/C weatherstrip kit will get you some square foam strips with which to seal the openings. Also, invest in a new fan clutch. I was amazed at the difference when I replaced mine. Even though I was experiencing no real engine cooling problems at the time, the A/C output was significantly better, especially around town. Good luck!

Very possbily is the MAF sensor causing the problem. My congratulations on finding these can often be cleaned instead of replaced, but sounds like you may be ready for a new one. The day/night thing can also be related to this. The purpose of the MAF is to relate to the computer just how much oxygen is in the air at the moment. Colder air is dense and has more oxygen, warm air has less. The MAF is one of the ways we can get away without the old carbuetor choke which would restrict the amount of air (and oxygen) until the engine warmed up. To a lesser extent, you will find the same thing happening with cool night air vs. a warm (or hot) day.
The ECT code is probably just computer telling you that it has seen the coolant temperature outside the range it was expecting. You already told me that your thermostat is acting up. Probably not the stop leak but who knows? Spend a couple of bucks and get a new one. Sounds like you're right on target with your diagnosis, Good luck!

Check the trans cooler, could be leaking into the radiator.

My 93 has GVWR for different engine/axle combinations on the tire pressure chart on the front door post.
#302 of 527 Heater hose connections
Jun 08, 2005 (7:17 pm)
Does anybody know how to disconnect the factory heater hose quick connects at the heater core? I have the special tool "borrowed" from Autozone, but I can't even see the things buried on my '93 under all the other hoses. Looking at the tool doesn't give me a clue as to how they are made....

I have a 1992 3.0 aerostar. 90k miles. Was running great until about two months ago. When in the morning I would start it an it would surge from stalling to idle. If I accelerated for 10 seconds it would run fine the rest of the day. Last Sunday i started it
It stalled out and wouldn’t start. It starts now but the engine runs really
Rich. Black smoke out the exhaust. Does anyone know if there is a common?
Problem like this out there, that usually turns out to be the oxygen sensor or throttle position sensor etc. Like to norrow it down if possible thanks

I have a 1992 xl . starts then runs rich. black smoke coming out of the exhaust then
stalls. mech looked at it,hooked up a computer but couldn't determine what was
causing the problem. It was developing this problem for two months. when I started
it, the engine would surge from almost stalling to idle. If i gave it gas for 10 seconds
it would run great the rest of the day. Last sunday it stalled after I started in the
morning and now runs bad with black smoke and will not Idle. I know
its one on the sensors just don't know which one. Have you had any engine
problems like this. Need to figure out best place to start. the van only
has 90k on it. thanks for any info

i own a 1992 ford aerostar. the side sliding door is jammed and i need to remove it in order to fix the broken handle. does anyone know how to get the door open and off? thanks so much
