How to Decode Aurora Cars
Vehicle identification numbers, or VINs, provide specific information about your Aurora vehicle. For instance, if you want to get an insurance quote, an insurance agent can use the VIN to get exact specifications for your car and prepare a relevant quote. Decoding templates provide a convenient way to decode your Aurora vehicle on your own.

Note the first three characters. They represent the World Manufacturer Identification, or WMI. For your Aurora, the WMI is 1G3; "1" for United States, "G" for General Motors" and "3" for Oldsmobile.
2Characters four and five describe the car line and series: "GS" or "GR" for Auroras.
3Look at character six to determine the body type, such as "5" for four-door sedan.
4Character seven describes the restraint system. For instance, "1" means the vehicle has manual seat belts.
5Character eight identifies the engine type.
6The ninth character is a check digit used to verify the VIN.
7Characters 10 and 11 identify the model year and assembly plant, respectively.
8The final six characters represent the production sequence number.
9Go to the Mitchell Support web page to view the range of VIN characters and explanations for features such as body type and restraint system.

How to Replace an O2 Sensor on an Aurora
The oxygen (O2) sensors on an Oldsmobile Aurora are a series of small sensors placed in the exhaust system that monitor the amount of unburned oxygen in the exhaust. The O2 sensors relay this information to the engines computer so it can make adjustments to help the engine to run more efficiently and lower vehicle emissions. The Aurora is equipped with four O2 sensors, one in each exhaust manifold, one between the exhaust manifold and catalytic converter, and one after the catalytic converter. You can use a diagnostic code scanner to determine which sensor is malfunctioning. If you do not own a code scanner, take your Aurora to an auto parts store; many have code scanners and will check your car for free.

Disconnect the ground cable from the negative battery terminal by loosening the retaining bolt and pulling the clamp off the negative terminal. Secure the ground cable so that it cannot accidentally contact the negative battery terminal.
2Raise the vehicle and support it with jack stands underneath the frame.
3Disconnect the wiring harness from the sensor. Follow the wires connected to the sensor until you find a plastic wiring connector. Separate the wiring harness by pulling the connector apart.
4Use a wrench to remove the sensor from the exhaust pipe or manifold.
5Thread the new O2 sensor into the exhaust pipe or manifold, and tighten it.
6Connect the wiring harness on the new O2 sensor to the plastic wiring connector that you removed from the old O2 sensor.
7Lower the vehicle.
8Reconnect the ground cable to the negative battery terminal. Tighten the retaining bolt that secures the ground cable to the negative battery terminal.
