Question
98 taurus automatic 6cyl.how to beed air out of system.

Answer
Hello and thanks for the question...I'll try to help.

Bleed engine cooling system as follows:
Select maximum heater temperature and blower motor speed settings. Position control to discharge air at A/C vents in instrument panel.
Start engine and allow to idle. While engine is idling, feel for hot air at A/C vents.
Start engine and allow to idle until normal operating temperature is reached. Hot air should discharge from A/C vents. The engine coolant temperature gauge should maintain a stabilized reading to within the NORMAL range and the upper radiator hose should feel hot to the touch. CAUTION: If air discharge remains cool and engine coolant temperature gauge does not move, engine coolant level is low in engine and must be filled. Stop engine, allow to cool and fill cooling system.
Shut engine off and allow to cool.
Check engine for coolant leaks.
Check engine coolant level in degas bottle and fill as necessary.
