• Q: How to Properly Service the Secondary Air Injection Pump on 2010 Cadillac DTS?

  A: The front air deflector must be removed before starting the secondary air injection pump replacement process. The engine harness electrical connector for the secondary air injection (AIR) pump must be disconnected first followed by quick connect fittings for both the inlet hose and outlet hose positioned at the AIR pump. Start by removing the AIR pump bolt followed by threading off the AIR pump nuts until the AIR pump becomes free to lift up and remove from the cradle bracket. The AIR pump integral nuts need to be aligned to cradle bracket holes before the pump can be lowered into position while tightening each nut to 10 Nm (89 lb in) and the bolt to 12 Nm (106 lb in). Reinstall the engine harness electrical connector to the AIR pump while at the same time connecting the outlet hose quick connect and inlet hose quick connect to the AIR pump. The last step includes reinstating the front air deflector.
