The smog pump, formally the secondary air injection pump, is belt-driven off the engine and pushes fresh air into the exhaust manifold so unburned hydrocarbons and carbon monoxide finish combusting, especially during cold starts when the mixture runs rich, as the live page explains. This unit carries a corrosion-resistant cast aluminum body, precision-machined internals for consistent air delivery, a factory-matched single-groove V-belt pulley pre-installed, and direct bolt-on mounting using the original Lynx points and hose routing.
The live FAQ lists the symptoms: check engine warnings, rough idle, increased emissions, and failed inspections. Forty-year-old pumps fail through worn vanes and seized bearings, and in testing states a dead pump is a guaranteed inspection failure, while removing the system outright is illegal where emissions equipment is required.
