For 1990-2009 cars

The cooling fans are located behind the radiator. The cooling fans are driven by an electric motor. The cooling fan motors both have five blades that are each 312 mm (12.3 in) in diameter. One cooling fan will start and run and then both cooling fans will run depending on the amount of cooling the radiator needs.

The advantage of the electric fan is less power drain on the engine and less fan noise. Also, there is no fan belt to inspect, adjust, or replace. This means less cooling system maintenance.

The engine cooling fan relays provide the current required for the motors based on a low current signal received from the powertrain control module (PCM).
