  Q: How to Replace the Secondary Air Injection Pump on Cadillac DeVille?

  A:

  The replacement of a secondary air injection (AIR) pump starts by elevating the automobile through safe methods. Begin replacing the left front wheel well/splash shield retaining screws from the front part allowing you to move and access the air pump assembly. First loosen and lower the clamp at the air outlet hose and disconnect the air inlet hose from the pump. Remove the electrical connector from the air pump. First detach the upper air pump to cradle bolt and after lifting it up you can pull out the air pump from its cradle bracket. To initiate installation start by feeding the lower air pump bolts/nuts into the cradle bracket while pushing it toward the bottom and afterwards installing the upper air pump to cradle bolt before tightening both lower and upper air pump to cradle bolts to 9 n.m (80 lb in). After connecting the electrical connector to the air pump, install both the outlet hose with its pinch clamp to the pump and then put on the inlet hose before lowering the vehicle.

  Q: How to service the Secondary Air Injection Pump for Bank 2 on Cadillac DeVille?

  A:

  Service of air injection pump for bank 2 begins by elevating the vehicle and unfastening screws at the front of the splash shield before lowering it to reach the air pump assembly. The servicing begins with opening the air exhaust hose pinch clamp before removing its hose from the air pump while carefully removing the hose and filter assembly from the pump. After disconnecting the electrical connector of the air pump you must loosen the lower air bracket nuts while removing the upper air to cradle mounting bolt. You should lift the air pump vertically from its cradle bracket position. Mount the lower air pump bolts/nuts into the cradle bracket followed by pushing it down before installing the upper air pump to cradle bolt which requires 9 n.m (80 lb in) torque setting. To check correct fitment of the air inlet hose/filter to the air pump you should hear a click while ensuring the rubber o-ring rests at the bottom of the air pump. The installation of the air pump requires assembly of the inlet hose/filter assembly to the pump then securing the pump exhaust hose to the airflow device with a clamp. The vehicle maintenance process concludes by attaching the air pump electrical assembly while placing the splash shield in position followed by securing the screws before lowering the vehicle.
