Electric Power Steering (EPS)
* How it Works: An electric motor assists the steering wheel, making it easier to turn, especially at low speeds. The motor's power is controlled by an electronic control unit (ECU) that factors in vehicle speed, steering angle, and other variables.
* Benefits:
* Improved Fuel Economy: No hydraulic pump constantly running, saving a bit of power.
* Quieter Operation: Less noise from the steering system.
* Better Steering Feel: Can provide more precise steering feedback.
* Space Savings: Eliminates the need for a hydraulic pump, freeing up space under the hood.
* Drawbacks:
* Potential for Electrical Issues: The system relies on electricity and can be affected by electrical problems.
* Cost: EPS systems are generally more expensive than manual systems.
* Limited Steering Feel: In some cases, EPS can feel artificial or disconnected.
Manual Steering
* How it Works: The steering wheel is connected directly to the steering column, requiring the driver to exert more force to turn the wheels.
* Benefits:
* Simplicity: A straightforward, mechanical system.
* Reliability: Generally more robust and less prone to failure than EPS.
* Direct Feel: Provides a more direct connection to the road and steering wheel.
* Drawbacks:
* Heavy Steering: Can be tiring for the driver, especially at low speeds or in parking lots.
* Reduced Fuel Economy: Requires more effort from the driver, leading to slightly higher fuel consumption.
Determining Your 2005 Malibu's System:
1. Check the Owners Manual: Your owner's manual will definitively state what type of steering system your car has.
2. Look for a Steering Column Motor: If your car has EPS, there will be an electric motor mounted near the steering column.
3. Listen for Pump Noise: A manual system will have a hydraulic pump near the engine, typically with a noticeable whine when the engine is running.
Important Note: The 2005 Chevy Malibu was available with both EPS and manual steering, so knowing your specific model is crucial.
