How to Replace the Secondary Air Injection Pump on GMC Envoy?

The first step for secondary air injection (AIR) pump replacement is to lift up the vehicle. First detach both air pipes from the air reaction pump before removing the Relay from its bracket and breaking the electric connector from the air pump. The installation begins by taking out the air pump from the vehicle after removing its 3 frame securing bolts. After placement of the air pump inside its installation slot position the three bolts on the vehicle frame until torque reaches 20 n.m (15 lb ft). Complete the electrical connector connection to the air pump followed by installing the electrical Relay on the air pump bracket then finalize contact between the air inlet and outlet pipes and the air pump by checking for debris before connection. Finally, lower the vehicle.
