The Oldsmobile Aurora is a full-size luxury sports sedan made by Oldsmobile from 1994 to 2003. The Aurora rides on the same Cadillac-derived G platform as the two-door Buick Riviera.
After much research and development, the Aurora went into production on January 24, 1994 and was released for the 1995 model year. This was the start of the first generation (1995–1999).
- 4.0 L (244 cu in) L47 V8 engine, a DOHC engine based on Cadillac's 4.6 L Northstar V8
The second generation Aurora (2001–2003) used the G-body design and the 4.0 V8 Northstar still mounted to a 4T80-E or the LX5 V6. The second generation Aurora was over six inches shorter than was the first generation.
- 2001–2002• LX5 3.5 L (212 in³) V6, 215 hp (160 kW) @ 5600 rpm, 234 lb⋅ft (317 N⋅m) torque @ 4400 rpm.
- 2001–2003• L47 4.0 L (244 in³) V8, 250 hp (186 kW) @ 5600 rpm, 260 lb⋅ft (353 N⋅m) torque @ 4400 rpm.

Cooling Fan Control
The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) to operate both fans together at low or high speeds. The cooling fan relays receive battery positive voltage from the underhood fuse block. The ground path is provided at G103.
During low speed operation, the PCM supplies the ground path for the low speed fan relay through the low speed cooling fan relay control circuit. This energizes the cooling fan 1 relay coil, closes the relay contacts, and supplies battery positive voltage from the cool fan 1 fuse through the cooling fan motor supply voltage circuit to the right cooling fan. The ground path for the right cooling fan is through the cooling fan S/P relay and the left cooling fan. The result is a series circuit with both fans running at low speed.
During high speed operation the PCM supplies the ground path for the cooling fan 1 relay through the low speed cooling fan relay control circuit. After a 3-second delay, the PCM supplies a ground path for the cooling fan 2 relay and the cooling fan S/P relay through the high speed cooling fan control circuit. This energizes the cooling fan S/P relay coil, closes the relay contacts, and provides a ground path for the right cooling fan. At the same time the cooling fan 2 relay coil is energized closing the relay contacts and provides battery positive voltage from the cool fan 2 fuse on the cooling fan motor supply voltage circuit to the left cooling fan. During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed.
