Get fresh air moving back into the exhaust stream during cold starts with the Standard Ignition Secondary Air Injection Pump (MPN AIP18). It installs as a direct-fit replacement for the listed applications: the 1999-2000 Chevrolet Blazer [V6-4.3L], 1998-2000 Chevrolet S10 [V6-4.3L], 2000 GMC Jimmy [V6-4.3L], 1998-2000 GMC Sonoma [V6-4.3L], and 1999-2000 Oldsmobile Bravada [V6-4.3L].
A secondary air injection pump forces extra air into the exhaust after a cold start, helping the catalyst reach operating temperature sooner so the vehicle can meet its emissions strategy.
Signs the original pump may need replacing include a secondary-air-related check engine light or a pump that runs loudly or not at all. Diagnose the cause before replacing, since related valves and hoses can produce similar symptoms; if a failed air pump is the cause, this replaces it.
Manufacturer part number AIP18.
