All my information tells me Ford stopped using the 4 cylinder engines for Aerostars in 1987 so you would have the 3.0 or 4.0 6 cylinder engine.
In a 1997 Ford Aerostar : Refrigerant 134a is used
If you asking what type of Freon is in a 1993 Aerostar, that would be R12. If you need to get it recharged, you will need to have it converted to R134A system since R12 is no longer available.
10w30
5W-30
A Ford Aerostar would have come from the factory with a 50 / 50 mix of distilled water and GREEN color antifreeze ( meeting Ford specification ESE-M97B44-A )
R-12.
I checked Chilton's and Haynes manuals and they both say to use Type F Automatic transmission fluid for the power steering.
What type of rear end do you have?
A 1995 model would have an R-134a system.
SAE 10W30 any major brand.
Supercharger oil for a 1993 Ford Thunderbird can be found at auto parts stores that sell racing performance parts. Usually, a 50 wt. oil will work for this type of engine.
