What Fluids Does A Tesla Use?


Tesla has become one of the leading electric vehicle manufacturers in the world, revolutionizing the automobile industry with their innovative and sustainable products. Unlike conventional cars, Teslas do not rely on internal combustion engines; instead, they harness the power of electricity. This shift in technology also affects the fluids used in Teslas. In this article, we will explore the various fluids that a Tesla uses and their respective functions.

1. Coolant

Coolant is a vital fluid used in Teslas to regulate the temperature of the battery pack. The coolant circulates through the battery cooling system to ensure that the battery operates within its optimal temperature range. It prevents the battery from overheating during high demand or extreme weather conditions.

  • Coolant helps maintain the battery’s performance and prolong its lifespan.
  • Regular coolant checks and top-ups are necessary to ensure the battery operates efficiently.
  • A malfunctioning coolant system can cause severe damage to the battery and affect the overall performance of the vehicle.

2. Brake Fluid

Even though Teslas use regenerative braking, they still require traditional hydraulic brakes that utilize brake fluid. Brake fluid is responsible for transmitting pressure to the braking system, allowing the driver to control the car’s speed and bring it to a halt when needed.

  • Brake fluid should be checked regularly and replaced according to the manufacturer’s guidelines.
  • Using the recommended brake fluid specified by Tesla is crucial for optimal braking performance.
  • Contaminated or degraded brake fluid can affect the braking efficiency and compromise the safety of the vehicle.

3. Transmission Fluid

Unlike conventional vehicles, Teslas do not have multiple gears or a traditional transmission system. Instead, they use a single-speed transmission or a direct drive system. Consequently, Teslas do not require transmission fluid like internal combustion engine vehicles.

4. Hydraulic Fluid

Hydraulic fluid is necessary for the proper functioning of power steering systems in conventional cars. However, Teslas do not have hydraulic power steering. They utilize electric power steering systems, eliminating the need for hydraulic fluid.

5. Washer Fluid

Washer fluid is used to clean the windscreen and provide better visibility while driving. Teslas, like any other vehicle, need the washer fluid for maintaining clear visibility.

  • Regularly check the washer fluid level and top it up when necessary.
  • Using the appropriate washer fluid for Teslas is essential to prevent damage to the system.
  • During cold weather, it is advisable to use washer fluid with antifreeze properties to prevent freezing on the windscreen.

6. Battery Coolant Additive

In some Tesla models, a battery coolant additive is required to prevent freezing of the battery coolant during extreme cold weather conditions.

  • The battery coolant additive should be used according to the manufacturer’s instructions.
  • Keep an eye on the battery coolant additive level and replenish it if necessary.
  • Using the recommended additive is crucial to ensure the coolant system operates effectively.

7. Air Conditioning Refrigerant

Teslas come equipped with advanced air conditioning systems to ensure passenger comfort. These systems utilize refrigerants to cool the air before circulating it in the cabin.

  • Regular maintenance of the air conditioning system and refrigerant level is necessary to avoid any performance issues.
  • Ensure that the proper refrigerant specified by Tesla is used.
  • Leaking refrigerant can affect the cooling performance and should be addressed promptly.


Teslas use a variety of fluids, albeit in lesser quantities compared to traditional internal combustion engine vehicles. Coolant becomes a critical fluid in Teslas, ensuring optimal battery performance and longevity. Brake fluid, washer fluid, and battery coolant additive are also essential for proper vehicle operation. However, Teslas do not require transmission fluid or hydraulic fluid due to their unique electric powertrain configuration. By understanding the fluids necessary for Teslas, owners can ensure their vehicles operate at peak performance while maintaining sustainable mobility.
