2.3 Liter Engine (Calif.)

  1. Remove thermo switch. Connect an ohmmeter across switch terminals and place sensor end of switch in a water-filled container. Heat or chill water gradually and use a thermometer to check temperature.
  2. Continuity should exist between both terminals at 131°F (55°C) or above for thermo switch and 50°F (10°C) or above for distributor thermo switch (if so equipped). Replace switch if not within specification.
