How to service and repair the Secondary Air Injection Pump on Chevrolet Express 3500?

Connector disconnection of the AIR pump harness plus AIR output hose detachment from the AIR valve initiates the service process for the Air Injection Pump. The first step requires removal of the bolt which supports the pump to the mounting plate until you can extract the pump. Installation of the AIR pump must start by following the Fastener Notice in Service Precautions before securely mounting the AIR pump. The AIR pump mounting bolt installation should be followed by tightening it to 17 N.m (13 lb ft). The installation process ends with connecting the AIR pump harness connector and AIR pump output hose to the AIR valve.
