Ford 1996 Aspire Manual page 190

If the engine is cold, the reservoir should be
filled with engine coolant to just above the
LOW mark, and the radiator should be full.
Engine coolant recovery reservoir
Adding engine coolant
Do not put engine coolant in the container
for the windshield washer fluid.
If sprayed to clean the glass, engine coolant or
antifreeze could make it difficult to see through
the windshield.
Add engine coolant only to the coolant
reservoir. If the coolant level is low, add to the
reservoir a 50/50 mixture of water and the type
of engine coolant that Ford specifies. You may
add water by itself only in an emergency, but
you should replace it with a 50/50 mixture as
soon as possible. Check the engine coolant again
the next few times you drive your vehicle.
Never remove the coolant recovery cap
while the engine is running or hot.
