The Mercury Secondary Air Injection Check Valve uses clean air shortly to the exhaust into cold starts to maintain the fumes low and the pump safe. Mercury won some reputation of midsize cars with soft rides, sharp styling and roomy cabins that dampened road noise, which was displayed by the classics such as the Cougar and Grand Marquis. The brand was established in 1938 and was named after the messenger god and in its showrooms, the company emphasized on style and reasonable prices. Mercury cars are said to have quiet cabins and long-term value by drivers. Mercury focused on fined tuning suspension and controls to ensure that the families move in comfort and through decades Mercury released convenience touches to make the process of driving a luxury before other companies followed suit. A Secondary Air Injection Check Valve is a small one way gate in the emissions system that will allow fresh air to flow to the catalytic converter but not allow back flow of hot exhaust and moisture. The primary responsibility of the Secondary Air Injection Check Valve is to accelerate the catalyst light off in order to ensure that bad gases fall out following ignition. To change the valve, you need to cool the engine, detach the battery and locate the piece on the SAI hose by the exhaust. Unscrew clamps, remove existing unit and gasket, check hoses, replace Secondary Air Injection Check Valve facing the arrow, install the hardware, reconnect lines and battery, clear the codes and ensure no leaks.
