In the engine compartment, there are four major belt or gear driven components. What are they?

- Power steering pump: The power steering pump provides hydraulic power to the power steering system, making it easier to turn the steering wheel.
- Alternator: The alternator generates electricity to charge the battery and power the vehicle's electrical system.
- Air compressor: The air compressor compresses air to power the air brakes, air suspension, and other pneumatic systems.
- Water pump: The water pump circulates coolant through the engine cooling system to keep the engine from overheating.
These components are essential for the safe and efficient operation of the vehicle. It is important to have them inspected and serviced regularly to ensure that they are working properly.
