When you have an electric cooling fan in your Buick Riviera, chances are that there's a Buick Riviera fan motor that operates the mentioned component. The fan is designed to maintain the engine's temps at the correct stage, but it isn't going to be able to do so with out the fan motor, the one which controls the fan.

The electric engine fan engages and disengages to regulate the engine temp, and it's the fan motor that operates behind the fan to Buick Riviera sure that its operation is successful. Fan motors are the electrical components that decide when the fan must engage and the timing when it should stop, based on the temp in the engine. You might consider the said components as the primary operator of the radiator fan; the hotness of the engine greatly relies on the performance of the engine fan plus motor, so the said parts have to always be in great shape. Or, any time the fan motor in your Buick Riviera becomes defective, the cooling fan would definitely die on you.
