How to Retrofit Electric Power Steering to a Classic Chevrolet Corvette?

As car enthusiasts, you understand the thrill of driving a classic car, the legendary Chevrolet Corvette. However, retrofitting older models with modern equipment can enhance the driving experience significantly. One such upgrade is the replacement of the traditional hydraulic power steering system with an electric one. Why would you want to do this? An electric power steering (EPS) system provides more precise steering control, reduces engine load, and improves fuel efficiency. This article will guide you through the process of adding an electric power steering kit to your classic Corvette.

Understanding the Importance of Power Steering

The term ‘power steering’ is something that you’ll come across often as car owners. The power steering system in your car is an integral part of the overall driving experience. It enables you to steer the car with less physical exertion. In classic cars like your Chevrolet Corvette, power steering was typically a hydraulic system, powered by the car’s engine.

However, the inevitable evolution of technology has led to the development of electric power steering systems, which are now standard in modern vehicles. These systems offer numerous advantages, including improved steering response, reduced engine load, and better fuel efficiency. Moreover, EPS systems are easier to install because they eliminate the need for hydraulic pumps, pulleys, belts, and fluid.

Choosing the Right Electric Power Steering Kit

When it comes to retrofitting your classic Corvette with an electric power steering system, it’s crucial to choose the right kit. Different kits are designed for different car models, and you must select one that is compatible with the Chevrolet Corvette.

While shopping for the kit, pay attention to the item specifics listed by the manufacturer. These include the make, model, and year of the car that the kit is designed for. Moreover, look at the details of the power steering pump, electric motor, and the wiring harness included in the kit.

The best way to ensure compatibility is to consult with a professional mechanic or contact the kit’s manufacturer directly. They can provide a quote for the price of the kit and its installation. Be sure to ask about any additional parts or modifications you will need to make during the installation process.

Retrofitting the Electric Power Steering System

Assuming that you have the right electric power steering kit, you are now ready to retrofit the system to your Corvette. Here are the general steps. Be sure to follow the specific instructions provided with the kit and seek professional help if necessary.

First, you will need to remove the existing hydraulic power steering system. This includes the pump, belts, pulley, and hydraulic fluid reservoir.

Next, install the new electric power steering pump. This unit can usually be mounted on the existing steering column, but additional supports may be needed depending on your kit and car.

Attach the wiring harness from the electric power steering pump to the car’s electrical system. If your kit includes a power steering control module, install it now.

Finally, connect the electric power steering pump to the car’s steering system. This usually involves attaching it to the existing steering column or rack and pinion system.

Protecting Your Investment With Steering Covers

After retrofitting the electric power steering system, you should consider additional measures to protect your investment. One such measure is using steering covers. These covers are not just cosmetic enhancements, but they also serve a functional purpose.

Steering covers provide an extra layer of protection to the steering equipment, preventing dust, dirt, and other contaminants from entering the system. They also protect the steering components from heat, reducing the risk of heat-related damage. Furthermore, steering covers reduce noise and vibration, enhancing your driving experience.

So, while retrofitting your classic Chevrolet Corvette with an electric power steering system, don’t forget to add a good-quality steering cover to your list. It’s a small addition, but it will go a long way in ensuring that your steering system performs optimally over the long term.

Engaging With The Community

Finally, it’s worthwhile to engage with the community of classic car owners and enthusiasts. There are many forums and social media posts dedicated to Chevrolet Corvette owners where you can share your experience of retrofitting an electric power steering system, ask questions, get advice, or even post a reply to someone else’s query.

You can also read about the experiences of others who have undertaken similar projects. Their insights and tips could be invaluable to you and might even prevent you from making costly mistakes. Remember, there’s no harm in seeking help or advice from those who have walked the path before you. After all, the car enthusiast community is always eager to share their passion and knowledge.

In sum, retrofitting an electric power steering system to a classic Chevrolet Corvette is not a casual weekend project. It requires a good understanding of the car’s existing steering system, the ability to choose the right electric power steering kit, and the skill to install it correctly. However, with careful planning, the right tools, and a little patience, it’s a project worth undertaking.

Tips for Operating the Electric Power Steering System

After you have successfully installed your electric power steering system in your classic Chevrolet Corvette, it’s time to learn how to operate it properly. This is not as tricky as it may sound, but it does require a bit of understanding of how electric power steering works.

Firstly, an electric power steering system is highly responsive. This means you will notice an immediate change in the feel and responsiveness of the steering wheel when you switch from a hydraulic system. It might take a bit of time to get used to this, so be patient and give yourself time to adjust.

Secondly, be aware that the electric steering system will feel lighter than the hydraulic system. This can make it seem like you have less control over the car, but that’s not the case. It’s simply that the electric power steering system requires less effort to use.

Thirdly, keep in mind that electric power steering systems are more energy efficient. This means that they can save battery power and reduce load on your engine, thereby improving your Corvette’s fuel efficiency.

Finally, remember to refer to the service manuals that come with your kit. These manuals will provide detailed instructions on how to operate and maintain your new electric power steering system.


Retrofitting a classic Chevrolet Corvette with an electric power steering system is a worthwhile upgrade that can significantly enhance your driving experience. Not only does this modern system provide more precise steering control, but it also improves fuel efficiency and reduces engine load. However, the process requires careful planning and some technical know-how.

From choosing the right electric power steering kit to installing it correctly, every step matters. It’s also advisable to invest in additional protection like steering covers and to engage with the community of classic car enthusiasts for advice and support.

Remember, patience is key here. Don’t rush the process. Take your time to understand how the electric power steering system works and to learn how to operate it properly. Refer to the service manuals and don’t hesitate to ask for help if needed.

In conclusion, while retrofitting your Corvette with an electric power steering system is not a simple task, it is certainly worth the effort. So, whether you’re a seasoned mechanic or a hands-on car enthusiast, why not take on this project and give your classic Chevrolet Corvette the upgrade it deserves?
