What Are the Maintenance and Repair Procedures for Secondary Air Injection Pump on Buick Regal?

AIR system used in models from 1975 to 1980 pumps compressed air into the exhaust system around the exhaust valves so as to help in burning the unburned exhaust gases; it comprises of air injection pump/hoses/valves/tubes directing the air to the exhaust manifolds. Adjustments as applied to carburetors and distributors are uniquely different for AIR engines and these components are not interchangeable with typical engines. A alternates between closing off the air entering the engine to stop backfiring when manifold vacuum rises and uses a diverter value at cruising to channel air through the pump muffler and expels it by a relief valve at high rpms. Check valves are used in the system to prevent exhaust gases from entering the pump, and the AIR system used in the 231 V6 engines has some differences in this aspect. The efficiency of the system depends on the idle speed, ignition timing and dwell, which must be checked from time to time and the hoses and fitting must be checked for wear and tightness and the drive belt for wear and tension every one year or every 12,000miles. As for access to the air pump: disconnect the air hoses, secure the pump pulley, loosen the mounting bracket bolt, remove the drive belt, unbolt the pump mounting bolts and then remove the pump; installation is the reverse of removal. Subsequently, for the diverter valve, the vacuum sensing line and other hoses need to be disconnected, and then the valve is unbolted from the connection, the original gasket must be replaced with a new one and then nuts and bolts must be tightened to around 85 INCH LBS.

Buick Regal Secondary Air Injection Pump

The Secondary Air Injection Pump in Buick Regal vehicles and needed for job in the Air Injection Reactor (AIR) system to provide fresh air into exhaust system as to oxidized unburned fuel which helps to decrease HC and CO emission. Usually this system comprises an electric or a belt-driven air pump, an air control valve in addition to several check valves and it controls the flow of air depending on the temperature and status of the engine. This Secondary Air Injection Pump is applied in Buick Regal models to inject air into the exhaust ports in the course of expediting warm-up in a bid to minimize emissions. When the engine is warm the air injection system switches to supplying air to the catalytic converter. Although there could be a range of modifications in various models of Buick Regal, which manufacture the Secondary Air Injection Pump, its main work remains predominant, the enhancement of efficacy of the exhaust emission decrease and preventing backfire during deceleration via the help of diverter and check valves.

Each OEM Buick Regal Secondary Air Injection Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part.

Adjustments as applied to carburetors and distributors are uniquely different for AIR engines and these components are not interchangeable with typical engines.

Check valves are used in the system to prevent exhaust gases from entering the pump, and the AIR system used in the 231 V6 engines has some differences in this aspect. The efficiency of the system depends on the idle speed, ignition timing and dwell, which must be checked from time to time and the hoses and fitting must be checked for wear and tightness and the drive belt for wear and tension every one year or every 12,000miles. As for access to the air pump: disconnect the air hoses, secure the pump pulley, loosen the mounting bracket bolt, remove the drive belt, unbolt the pump mounting bolts and then remove the pump; installation is the reverse of removal. Subsequently, for the diverter valve, the vacuum sensing line and other hoses need to be disconnected, and then the valve is unbolted from the connection, the original gasket must be replaced with a new one and then nuts and bolts must be tightened to around 85 INCH LBS.
