Oxygen Sensor wrench (J 39194). The in-line electrical connector and the louvered end of the ho2s and Oxygen Sensor require special handling for cleansing from soil and oil substances while any cleaning solvents must be avoided. Start by uninstalling the fuel injector sight shield first. When engine temperature falls below 48°c (120°F) the Oxygen Sensor becomes hard to remove because excessive force could break the Exhaust Manifold or Exhaust Pipe threads. Separate the ho2s electrical cpa retainer while you disconnect the ho2s wiring harness from its electrical connector. Use the Oxygen Sensor wrench (J 39194) to carefully take the ho2s out of the right Exhaust Manifold. Placing the rear Oxygen Sensor into the right Exhaust Manifold requires a special anti-seize compound which should be applied to reused sensor threads using p/n 12377953 or equivalent. Use the Oxygen Sensor wrench (J 39194) to torque the ho2s to 41 n.m (30 lb ft) before reconnecting ho2s electrical connector to its bracket and installing the electrical connector retainer after attachment of the harness electrical connector.
