The 1998 Ford Taurus dipstick is located
on the driver's side of the engine, near the front. It's usually a yellow or bright colored handle, making it relatively easy to spot. Look for a long, slender handle sticking up from the engine valley.
However, without seeing the engine, this is the general location. A quick online search for "1998 Ford Taurus engine bay diagram" could provide a visual confirmation.
