What’s the Best Strategy for Installing Additional Cooling Fans in a Honda S2000 for Track Use?

When it comes to track racing, the Honda S2000 is a vehicle that performs admirably. Designed for high-speed driving and impeccable handling, this speedster offers both versatility and power. However, when you’re pushing your S2000 to its limits on the racetrack, maintaining optimal engine temperature is crucial. Overheating can lead to engine damage and reduced performance.

That’s why, in many cases, track enthusiasts opt to install additional cooling fans in their Honda S2000. But what’s the best strategy for doing so? This article addresses this question, delving into the intricacies of the cooling system and providing a guide to increasing your vehicle’s cooling efficiency.

Overall Strategy

Before we dive into the details, it’s important to outline an overall strategy to follow when installing additional cooling fans in your Honda S2000.

You want to ensure that the additional fans will improve the efficiency of the cooling system. The key here is not just to add more fans, but to install them strategically to maximize airflow through the radiator and engine bay. It involves assessing your car’s current cooling system, determining where improvements can be made, and, finally, choosing and installing appropriate auxiliary fans.

Analyzing Your Current Cooling System

Understanding the performance of your current cooling system is the first step towards improving it. By analyzing its performance, you can identify potential areas for improvement.

Start by running your S2000 on the track and keep an eye on the temperature gauge. If the engine is running hot frequently, it’s an indication that your cooling system may not be up to the task.

Next, inspect your radiator and existing fans. Ensure that the radiator is in good condition and the fans are working properly. Any issues here could be contributing to cooling inefficiencies that additional fans alone may not solve.

Choosing the Right Auxiliary Fans

The effectiveness of your upgraded cooling system will largely depend on the auxiliary fans you select. It’s not just about getting the biggest or most powerful fans. You’ll need to consider several factors, including size, power draw, and airflow.

Firstly, the fans need to fit in the available space. Measure the area where you plan to install the additional fans. Consider using slim fans if space is a concern.

Secondly, take into account the power draw of the fans. More powerful fans draw more power, which could strain your electrical system.

Lastly, look at the airflow rating of the fans. This tells you how much air the fan can move per minute. Higher numbers mean more cooling potential.

Installing the Additional Fans

Now, let’s move on to the installation process. This is where careful planning and execution come into play.

Before you start, you need to decide where to install the fans. There are two main options: in front of the radiator (pusher configuration) or behind it (puller configuration). Each configuration has its advantages and disadvantages.

In a pusher configuration, the fan pushes air through the radiator. This configuration is generally easier to install and better for cars with limited space. However, it’s less efficient than a puller configuration.

In a puller configuration, the fan pulls air through the radiator. This configuration is more efficient, as it draws more air through the radiator. But it’s more challenging to install and may require more space.

After deciding on the configuration, you can proceed with the installation. This typically involves mounting the fans, connecting them to the electrical system, and setting up a control mechanism.

Optimizing Fan Control for Track Use

Finally, to maximize the effectiveness of your additional fans, you should optimize their control for track use.

The simplest way to control the fans is with a thermostatic switch. This switch turns the fans on and off based on the coolant temperature. However, this might not be ideal for track use, as the fans only kick in when the engine is already hot.

A better option might be to use a manual switch or a programmable controller. This gives you more control over when the fans turn on. For instance, you could turn on the fans before a demanding section of the track to pre-cool the engine.

Remember, installing additional cooling fans in your Honda S2000 for track use is about more than just adding fans. It’s about optimizing the entire cooling system to keep your car running at peak performance. With careful planning and execution, you can ensure your S2000 stays cool, no matter how hard you push it on the track.

Maintenance and Troubleshooting for Your Cooling System

Maintenance is crucial in ensuring the longevity and efficiency of your upgraded cooling system. Regular checks and inspections can help detect any issues early and prevent significant damage or failures.

Begin by inspecting the fans and their connections regularly. This includes checking for any loose or frayed wiring that could affect the fans’ operation. Moreover, cleaning the fans regularly is also important. Over time, dust and debris can accumulate on the fans, potentially hindering their performance.

Radiator maintenance is also vital. Regularly check the radiator for any leaks, damage, or blockages. A damaged or blocked radiator can significantly impact the effectiveness of your cooling system and may even lead to engine overheating.

Lastly, monitor the performance of your cooling system while on the track. Keep a close watch on your S2000’s temperature gauge during races. If the engine temperature seems higher than usual, it may indicate a problem with your cooling system.


Optimizing your Honda S2000’s cooling system for track use involves much more than simply adding extra fans. It demands a comprehensive strategy that takes into account your current cooling system, the right choice of fans, their installation, and ongoing maintenance.

Remember, the purpose of installing additional cooling fans is to enhance the performance and durability of your car on the track. It’s about ensuring that the engine operates within the optimal temperature range, even under the most demanding conditions. This can help prevent engine damage and maintain your S2000’s performance on the track.

With the right approach, you can effectively upgrade your Honda S2000’s cooling system, ensuring that your car remains cool and performs at its best on the track. Regardless of how hard you push your car, a well-optimized cooling system will ensure your S2000 maintains its performance and handles the heat of the track.
