What is a Serpentine Belt?
A serpentine belt is a long, continuous belt that is used to drive multiple peripheral devices in an engine. Unlike older vehicles that had multiple belts for different components, modern vehicles, including the 2010 Ford Fusion, utilize a single serpentine belt to streamline the process.
Functions of the Serpentine Belt
The serpentine belt is responsible for driving several key components within the engine. Its primary functions include:
1. Alternator: The serpentine belt powers the alternator, which generates electricity to recharge the battery and power electrical systems.
2. Power Steering Pump: It helps in operating the power steering pump, making it easier to steer the vehicle.
3. Air Conditioning Compressor: The belt drives the air conditioning compressor, essential for cooling the cabin.
4. Water Pump: In some engine designs, the serpentine belt may also drive the water pump, which is crucial for engine cooling.
