How to Handle an Alternator Issue After Power Steering Fluid Leak: DIY Tips vs Professional Services

Many car owners encounter issues where power steering fluid apparently leaks onto the alternator, resulting in a failed alternator. The common misconception is that the fluid directly caused the failure, but in reality, the damage may be more complex and require more than just cleaning. In this article, we explore whether you can clean out the alternator or if you need a new one due to the contamination from the power steering fluid.

Understanding the Issue

The leak from the power steering fluid did not cause the alternator to fail. However, there are several potential areas of contamination that could lead to mechanical failure. For example, oil from the steering fluid may have contaminated the slip rings, which are a critical part of the alternator. Additionally, the internal bearings and brushes of the alternator may need cleaning and re-lubrication. These components are essential for the proper function of the alternator, and simply spraying alcohol or brake cleaner may not suffice.

Recommended Actions

If you suspect the alternator is contaminated or failed, here are the steps you can take:

Diagnose the problem: Have a professional diagnose the alternator issue to confirm if it's due to the power steering fluid leak or other causes. Check for replacement parts: See if a set of brushes for the alternator is available, as these can be crucial for operation. Professional cleaning and repair: Clean the alternator using brake cleaner and ensure it is properly re-assembled. Although cleaning can be attempted, it's often best to have a professional handle the task to avoid further damage. Replacement: If cleaning and repair are not viable options, consider replacing the alternator with a new, rebuilt, or junkyard unit. A new alternator is the best option, while rebuilt and junkyard units are also viable alternatives.

DIY Alternator Cleaning Guide

If you decide to try cleaning the alternator yourself, follow these steps:

Disassemble carefully: Before taking apart the alternator, draw a line or mark the sections to ensure proper re-assembly. Remove contamination: Clean the alternator using brake cleaner, ensuring to blow out any remaining debris. Use alcohol as a solvent, as it is more effective for removing oils and fluids. Re-lubricate and re-assembly: Re-lubricate the internal bearings and brush sets and re-assemble the alternator according to the marks made earlier.

Remember, the risk of improper re-assembly can lead to further mechanical failure, especially with the sensitive components of the alternator. It's often safer to have a professional perform the cleaning and re-assembly if you are not confident in your abilities.

Conclusion and Final Thoughts

Your alternator is likely damaged due to the contamination from the power steering fluid. Once you fix the leak and start the car, you will be able to see if the alternator is functioning properly.

While it's possible to clean and repair the alternator, it's important to consider the extent of the damage and the potential risks involved. If cleaning and repair are not feasible, it is often recommended to replace the alternator with a new or rebuilt unit for reliable performance.

FAQs

What if the alternator failed due to internal short circuits? In such cases, the best course of action is to replace the alternator. Check if the alternator model and make are available in the market before making a decision. Can the brushes be replaced independently? Brushes are a critical part of the alternator. If you can find a set of brushes, they can be replaced, but professional assistance is often required for proper re-lubrication and re-assembly. What are the signs that I need a new alternator? If you notice that the alternator is not charging the battery, the light on the dashboard stays on, or the battery is drained quickly, it might be time to replace the alternator.

Good luck!
