Less than ten dollars.
20.0 gallons for Mercury Villagers '93-'98.
93-97.
I'm not familiar with any such procedure on this vehicle.
It is inside the dashboard towards the center at the very back. It is VERY hard to get to.
You can use any standard antifreeze, there is no special type required.
These vehicles are very similar and virtually all parts interchange.
There is no way to 'test' a timing belt. On your 1993, Mercury suggests it be replaced every 64K miles.
It will not idle at the proper speed (750 RPM).
It came from the factory with R12 (Freon). As R12 is so very expensive, I would convert this car to R134a. You can buy a conversion kit at most auto parts stores. If you have leak, make sure to have the leak repaired.
