• Q: How to Replace the Secondary Air Injection Pump on 2007 Cadillac DTS?

  A: The replacement procedure starts by removing the front air deflector while you detach the engine harness electrical connector from the secondary air injection (AIR) pump and unfasten the AIR pump inlet hose quick connect fitting and outlet hose quick connect fitting leading to the AIR pump. First detach the AIR pump bolt before loosening the AIR pump nuts then use a lifting method to remove the AIR pump from the cradle bracket position. When installing align the AIR pump integral nuts to the bracket holes before pushing the pump down while tightening the nuts to 10 N.m (89 lb in). Fasten the AIR pump bolt until it reaches a torque setting of 12 N.m (106 lb in). Set up the AIR pump outlet hose attachment point and the AIR pump inlet hose attachment point to the pump before reconnecting its harness electrical connection and reinstalling the front air deflector.
