1975
No, the first catalytic converters installed on GM vehicles was in 1975.
8 years or 80,000 miles which ever comes first
Actually it is not the muffler that contains platinum it is the catalytic converter. The catalytic converter (or "cat" as muffler shops and mechanic's call them) is usually in front of the muffler.
On a 2004 GM 1500 Sierra truck, the oxygen sensors are typically located in two places: upstream (pre-catalytic converter) and downstream (post-catalytic converter). The upstream oxygen sensor is found on the exhaust manifold or just before the catalytic converter, while the downstream sensor is located after the catalytic converter in the exhaust system. To access them, you may need to raise the vehicle for better visibility. Always consult the vehicle’s service manual for specific details and locations.
Yes, it is supposed to anyway. it is located under the front part of the cab.
There are two oxygen sensors. One located on the exhaust manifold and one located after the catalytic converter.
On GM, bank one is drivers side of engine, bank 2 is passengers side. Sensor(s) 1 is the upstream sensor, meaning BEFORE catalytic converter. Sensor(s) 2 are located downstream, or AFTER the catalytic converter, therefore, bank 2, sensor 2 is located in the exhaust pipe leading from the passenger side of engine and after the catalytic converter.
Depending what vehicle and year you have, if the cat was failing on a 1996 or newer GM vehicle it would light the "check engine" light.
Catalytic converter efficiency failure, bank two. That would be the passenger side.
The B1 S2 is located in the exhaust system from the drivers side of engine after the catalytic converter.
