FORD 1998 Taurus - Manual (Page 138)

If the engine coolant has not been checked at the
above recommended interval, the engine coolant
reservoir may become empty. If this occurs, add
engine coolant to the reservoir. For more
information on engine coolant maintenance, refer to
Adding engine coolant in this chapter.
Automotive fluids are not interchangeable; do not
use engine coolant, antifreeze or windshield washer
fluid outside of its specified function and vehicle
location.
Adding engine coolant
Do not put engine coolant in the reservoir
for the windshield washer fluid.
Do not mix conventional green coolant, orange
coolant or recycled coolants together in your
vehicle. Use only the type of coolant that your
vehicle was originally equipped with . If you
are unsure which type of coolant your vehicle
requires, contact your local dealer.
If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
When the engine is cool, add a 50/50 mixture of
engine coolant and water to the engine coolant
reservoir. Add straight water only in an emergency,
but you should replace it with a 50/50 mixture of
coolant and distilled water as soon as possible.
Check the coolant level in the coolant reservoir the
next few times you drive the vehicle. If necessary,
add enough of a 50/50 mixture of coolant and water
to bring the liquid level to the fill line on the
reservoir.
