THERMACTOR Idle Vacuum (TIV) Valve
- With engine at idle and transmission in Neutral, apply vacuum to small nipple and place fingers over TIV valve atmospheric vent holes. See Fig 1 . If no vacuum is sensed, TIV is damaged and must be replaced. If vacuum is sensed, go to next step.
- With engine at idle, apply vacuum to TIV valve large nipple using a vacuum pump. See TIV VALVE (LARGE NIPPLE) VACUUM SPECIFICATION . If vacuum is not held, TIV is damaged and must be replaced. If no vacuum is sensed, replace valve.
