How does a Ford smog pump work?
The smog pump is responsible for supplying fresh, pressurized oxygen into the exhaust stream near the exhaust manifold. The spinning vanes of the air pump forcing air into the diverter valve accomplish this. This vacuum is created by the exhaust gases as they travel down the exhaust passages at a high rate of speed.
When did smog pumps come out?
Smog pump use started on the ’66 models in California. Starting in ’68 the remaining States and Canada with the following criteria began using them: All V8s with open-element air cleaners (they didn’t use preheated air from the Thermac, which was considered and emission control device itself);
What cars have smog pumps?
To be specific, the trims include the Legacy 2.5GT, Outback 2.5XT, Forester 2.5XT, and the Impreza 2.5GT, WRX, and WRX STI. Also known as the smog pump, the secondary air-injection pump sends air into the exhaust stream directly after the manifold to burn up unwanted hydrocarbons.
How do you test a smog pump?
You just take the outlet hose off the rail and check if it is pumping air. If the pump is off the truck, you just spin the pulley and see if air comes out the outlet.
