Where do you put the power steering fluid in a 2006 Chevy Cobalt?
The 2006 Chevy Cobalt generally does not require adding power steering fluid, because it uses electric power steering (EPS). There is no dedicated reservoir for fluid in most models. If you’re experiencing steering problems, the issue is more likely electrical, mechanical, or related to the battery rather than fluid level. This article explains how to verify the system and what to check.
Does the Cobalt use electric or hydraulic power steering?
Most 2006 Cobalt models use electric power steering, which means there is no power steering pump or fluid to fill. Instead, an electric motor provides assist based on inputs from the steering wheel and sensors. If your vehicle uses a hydraulic system, you would have a power steering fluid reservoir and service instructions that differ from EPS.
How to determine your exact setup
Use these checks to confirm whether your car has EPS or hydraulic PS before you attempt any fluid maintenance.
- Inspect under the hood for a power steering fluid reservoir. A labeled reservoir with a cap typically indicates hydraulic PS; absence of a reservoir or a description of EPS on a label suggests electric PS.
- Look for a power steering pump driven by the accessory belt. If no pump is visible for steering, EPS is likely in use.
- Consult the owner's manual or a GM service sheet for your VIN to confirm the steering system.
Conclusion: In the absence of a PS fluid reservoir and pump, your 2006 Cobalt uses EPS and does not require PS fluid addition.
What to do if you suspect steering problems
If you notice symptoms such as stiffness, error lights related to steering, or unusual noises, the cause may be EPS failure, low battery voltage, or electrical wiring issues rather than a fluid level. Here are steps to take:
- Check the vehicle's battery and charging system; EPS relies on proper electrical power. A weak battery can cause steering assist to feel heavy or intermittent.
- Inspect the serpentine belt for wear or looseness; while EPS doesn't have a fluid pump, the belt powers other components that can indirectly affect steering through loaded systems.
- Check for diagnostic trouble codes with an OBD-II scanner and refer to the owner's manual for EPS-related codes.
If problems persist, have a qualified technician inspect the EPS motor, steering angle sensor, and related wiring.
Summary
For the 2006 Chevy Cobalt, you typically do not add power steering fluid because the car uses electric power steering (EPS). There is no reservoir. If your vehicle shows signs of steering trouble, verify the system type, check electrical and belt conditions, and consult a professional if needed.
What are common problems with a 2006 Chevy Cobalt?
Common problems for the 2006 Chevy Cobalt include issues with the ignition system (failing coils or module), timing chain (breaking or tensioner failure), stuck ignition key due to a failed shifter cable, and a flickering check engine light from a bad gas cap. Other potential problems are transmission issues, the AC not working correctly, and random misfires caused by vacuum leaks or faulty sensors.

Engine and performance
- Ignition Module/Coil Failure: A failing ignition module or coil can cause a misfire, leading to a rough-running engine and a check engine light.
- Timing Chain Issues: The timing chain can break or fail, especially after 100,000 miles, potentially causing significant engine damage.
- Misfires: Random misfires can be caused by various issues, including vacuum leaks, a bad gas cap, or a faulty oxygen sensor.
- Transmission problems: Some owners have reported issues with the transmission, which could be caused by low fluid levels.
- AC issues: The air conditioning may not blow cold air, and using the AC or heater can cause the engine's RPMs to bounce.
Electrical and other issues
- Stuck ignition key: The key can get stuck in the ignition if the automatic transmission shifter in the floor console fails.
- Bad gas cap: A faulty gas cap can trigger the check engine light.
- Corroded ground wires: A corroded ground wire on the front of the transmission is a common source of electrical problems, such as the battery light coming on randomly.
- Failed radio: In some cases, a failed radio has been known to take down the body control module, preventing the car from starting.

Do Chevy Cobalts take power steering fluid?
I haven't dealt with this personally, but Cobalts use an all electric power steering system, so there's no fluid.
Where is my power steering fluid reservoir located?
This step is quite simple, as power steering fluid reservoirs are usually located in the same place, except for a few. The reservoir could be made of either plastic or metal, and you can usually find it towards the rear of the engine bay, typically on the driver's side.
Does a 2005 Chevy Cobalt have electric power steering?
The 2005 Chevy Cobalt LT uses an Electric Power Steering (EPS) system prone to faults in the torque sensor or control module. When power steering cuts out and resets after restarting, check the EPS fuse and wiring harness for damage. Faulty torque sensors can cause the system to disable temporarily.
