Get your cold-start emissions system moving again with the Dorman - OE Solutions Secondary Air Injection Pump (306-016). It drops in as a direct-fit replacement for the 2006-2011 Buick Lucerne and 2006-2011 Cadillac DTS with the V8-4.6L engine. A secondary air injection pump forces fresh air into the exhaust stream during cold starts, helping the catalytic converter reach operating temperature faster and lowering cold-start emissions.
If a failed air injection pump is the cause of an air-injection trouble code or a pump that no longer moves air on cold start, this replaces it — diagnose the cause first, since valves, hoses, or wiring can produce the same symptoms. Consult the vehicle service information for the correct mounting fasteners and whether they may be reused. Country of origin: China. Manufacturer part number 306-016.
