All Except 2.3L California Models

  1. Remove thermo valve from bottom of intake manifold. Attach a length of hose to each valve outlet and place valve in container of water with thermometer.
  2. Slowly heat up water. When cold, no air should pass through valve (blow through vacuum line which does not go to EGR valve). When water reaches 130°F (55°C) on 2.0L engines or 140°F (60°C) on 2.3L engines, air should pass through valve. If not, replace thermo valve.
