What Fluid Does Tesla Have? (Explained)

Maintaining a Tesla vehicle is the first and most common question that arises in your mind while purchasing a new Tesla car. To maintain the continuous operation of your Tesla vehicle and to provide optimum lubrication, your Tesla requires fluids. What type of fluids your Tesla utilizes is essential for keeping the car in top operating condition?

If you are unfamiliar with this topic but want to gain knowledge on Tesla fluids, in this article I will explain it to you in-depth and provide some helpful information.

Let’s Get Started…!!!

What Kind of Fluids Does Tesla Have?

Your Tesla requires Tesla Engine Coolant that is very specific for your Tesla vehicles. Traditional internal combustion engines are absent from your Tesla vehicles. Instead, to guarantee effective performance they regulate the temperature of their electric components with coolant.

Your Tesla employs a variety of fluids, such as braking fluid, battery and drivetrain coolant, and windshield washer fluid. In this section I will explain all the fluid components of your Tesla to you in detail:

1)  Brake Fluid

Like other electronic cars, your Tesla car also required brake fluid in its hydraulic brake system. You should check your Tesla brake fluid if you frequently use your vehicle because it degrades with time.

Your brakes won’t be as responsive when this occurs. Degradation of this fluid is occurring due to many potential causes. Tesla is utilizing the best practice of monitoring your brake fluid every two years.

Below are the different types of brake fluids required by your Tesla vehicles:

●      DOT 3

The DOT 3 braking fluid in your Tesla is a glycol-based lubricant. It is hygroscopic in nature, which means that with time, it will collect moisture and may also cause corrosion in your braking system. It requires less braking, for this reason, you should add Dot 3 for your regular transportation.

●      DOT 4

The DOT 4 braking fluid in your Tesla is glycol-based and is frequently used in high-performance automobiles. It is also hygroscopic in nature, but less prone to moisture than Dot 3.

●      DOT 5.1

The DOT 5.1 braking fluid in your Tesla is also hygroscopic, but less prone to moisture than DOT 3 and DOT 4 brake fluid.

2) Coolant Fluid

Your Tesla vehicles require a specific temperature to operate effectively. To control the temperature of the battery and other parts your Tesla requires coolant. Any extra heat produced by the components is absorbed by the coolant while keeping everything within the optimum temperature range.

The advanced feature of your Tesla vehicle is that it does not require coolant changes as frequently as other electrical vehicles do. Because your Tesla batteries are not exposed as compared to other vehicles.

With the evaluation of automobile technology, Tesla is also working hard to provide you with the latest technologies. For this reason, know you even do not need to change your coolant fluid. But you need to read the owner’s manual that comes with your Tesla vehicle.

There are two different types of battery coolants in your Tesla vehicles: ones based on ethylene glycol and ones based on propylene glycol.

●      Glycol-based coolant: It is the riskiest coolant due to its high heat capacity and low freezing point. It is dangerous when it’s released into the atmosphere. Some of your Tesla models employed coolants based on ethylene glycol (Model S and Model X vehicles).

●      Propylene glycol coolant: In recent models (Model 3, Model Y, and revised Model S and X), your Tesla vehicles moved to Propylene Glycol-based coolant due to the safety concerns associated with Ethylene Glycol-based coolant. It has lower heat capacity, is less harmful, and is safer for you and the environment than ethylene glycol-based coolant.

The quantity of the coolant mixture in your Tesla vehicle is also important and of great concern for you. You should maintain the prescribed range to achieve ideal heat transformation and to avoid the coolant freezing or boiling.

You can adjust or monitor the coolant concentration by using your Tesla vehicles’ battery management systems. You should select your coolant type with great caution because it will directly impact the efficiency of your vehicle. 

3)  Windshield Fluid

If you love to drive a Tesla car, you also need to be concerned about windshield fluid. It is not as important for you as other fluids but you can maintain 100% vision even in challenging weather by using windshield fluid.

Some people think that to clean your windshield water is sufficient. But you should keep in your mind that windshield fluid has superior cleaning qualities that operate well during your drive. If you are living in a chilly environment windshield fluid is especially crucial with anti-freezing characteristics.

Two different forms of windshield fluid will help you to protect your windshield in different temperatures:

●      Summer windshield fluid: You can use the summer windshield fluid to remove dirt and grime from your windshield.  It is a water-based solution with a tiny bit of detergent. When you are living in warm regions, it works well for you to clean the windshield. But in winter it might freeze and impair visibility.

●      Winter windshield fluid: You can use the winter windshield fluid to avoid freezing in cold weather. It has a more concentrated solution with additional alcohol and other ingredients. If you are living in cold environments, it easily cleans your windshield. It also aids in melting ice or snow from the windshield. They are more expensive than summer washer fluid.

The qualities of the washer fluid you are using are also important and have an impact on the effectiveness and durability of the windshield wipers. For instance, if you use poor-quality or diluted wind washer fluids, they can damage the wiper blades which can result in reduced visibility.

Tesla does not specify the brand or kind of washer fluid you must be used, but the Tesla team suggests you use a premium washer. You can use windshield fluid mixed with more alcohol to avoid freezing in colder climates.

You should always select the washer fluid that is more compatible with your environment. You should make the right choice of windshield fluid to maintain visibility and drive safely.

4) Transmission Fluid

Tesla vehicles use different types of transmission fluids based on the series of your Tesla to ensure optimum performance. There are two types of transmission fluids that your Tesla cars utilized.

The one that provides improved performance is DEXRON VI. It will provide you with enhanced oxidation stability and foaming resistance. While the other that can be used in your Tesla vehicle was developed by Ford and named MERCON LV It also provides you with outstanding oxidation resistance and wear defense.

●      Model X and S

Mobile SHC 629 is the best transmission fluid for your Tesla X (2015-2020) and S (2012-2020) Models. DEXRON VI can also be used in the rear-wheel drive unit, you can also use. You should apply it to the exact place.

You can also apply this fluid in your small rear-wheel drive (2250 ml), big rear-wheel drive unit (1400 ml), and compact front-wheel drive vehicle (1750 ml),.

●      Model 3 and Y

Pentosin ATF 9 (Automatic Transmission Fluid) is best for your Tesla 3 and Y model. ATF 9 is a synthetic transmission fluid that helps you with extra wear protection, oxidation stability, and foaming. In contrast of it, you can also use ATF 1 transmission fluid in your rear-wheel drive unit (2129 ml) and the front-wheel drive unit (1183 ml).

How to Take Care in the Future?

To function properly, your Tesla requires different types of fluids. But you have the knowledge of the fluids your Tesla vehicle requires in order to work properly and for the safety of your vehicle. Some precatory measures are as follows:

1) Use the fluid according to your climate.

2) After every six years, replace your tires even if they are in good condition.

3) Rotate your Tesla tires every 10,000–12,000 miles.

4) You should also focus on your regenerative braking technique.

5) For better results, after every two years, change the carbon air filter.
