Oil Level Switch

  1. Remove engine oil level switch. See COMPONENT LOCATIONS . With switch sensor temperature less than 104°F (40°C), check for continuity in each float position. Continuity should exist in all float positions.
  2. Heat switch to above 140°F (60°C) in oil bath. Continuity should exist between switch connector terminals with float in up (on) position. Continuity should not exist with float in down (off) position. If switch operation is not as specified, replace switch.
