Windstar V6-232 3.8L (1995)
Case: Service and Repair
Thread Repair
1. Drill out damaged threads, using the same drill size as the thread O.D. For example, use a 5/16-inch drill for a 5/16 x 18 thread.
2. Select proper special tap and tap the drilled hole. Tap is marked for size of thread being repaired. Thus, the special tap marked 5/16 x 18 will not
cut the same thread as a standard 5/16 x 18 tap. It does cut a thread large enough to accommodate the insert, and after the insert is installed the
original thread size (5/16 x 18) is restored.
3. Place insert on tool and adjust sleeve to length of insert being used. Press insert against face of tapped hole. Turn tool clockwise and wind insert
into hole until insert is one-half turn below face.
4. Working through insert, bend insert tang straight up and down until it breaks off at notch.
5. Improperly installed inserts can be removed with extractor tool. Place extractor tool in insert so that blade rests against top coil one-quarter to
one-half turn away from end of coil. Tap tool sharply with a hammer so that blade cuts into insert. Exert downward pressure on tool and turn it
counterclockwise until insert is removed.
