Tesla Battery Coolant: Importance and Maintenance

If you own a Tesla, you might have seen the low coolant warning on your screen. While some might think of taking matters into their own hands and replacing the coolant themselves, it’s important to note that DIY Tesla battery coolant replacement isn’t recommended. Instead, it’s suggested to call Tesla to fix the issue, which can cost between $200 to $900.

The reason for this is that Tesla uses a specialized coolant that doesn’t match with other fluids found in stores or auto shops. While it may seem expensive, it’s important to understand the whole story before attempting to replace the coolant yourself. In this article, we’ll delve into the details of Tesla coolant and why it’s not recommended to replace it on your own.

Tesla Battery Coolant Replacement Is Prohibited!

Digging The Tesla Battery Coolant Replacement Cost

Tesla coolant replacement cost can vary from $200 to $900. The cost is based on the damage and difficulty of the labor. If it’s about coolant drain and refill, then Tesla Service Center will take around $200 – $250 counting labor. However, the replacement of battery coolant will require up to $600 – $900 where they change the old radiator with a new one and then refill the fluid. It can be less or higher than the mentioned amount if the labor is difficult.

How Often Do You Change Tesla Coolant?

Tesla suggested changing the coolant every 3 – 4 years by draining and then refilling the fluid. But Tesla has edited this out from the owner’s manual. After 2016, Tesla advice to never change the battery coolant in most situations. It’s because Tesla cars use batteries to operate (electric power instead of gas power) that seem to stay cool in all scenarios, unlike motor cars. Due to this sole benefit, they guarantee that the battery coolant will last for life and won’t require replacement.

Do Tesla Batteries Have Liquid Cooling?

Tesla Model 3, Y, X, and S batteries don’t use liquid cooling which contains only water. In the MX, M3, and MS, the cars use G-48 ethylene-glycol fluid in battery coolant that contains 60% ethylene glycol and 40% purified water to ensure ideal operation. On the other than, the MY cars use blue G-48 and orange-red HTF-LS fluids that include 50% antifreeze with 50% purified water. That means Tesla cars don’t have a liquid cooling system in the battery.

Tesla battery coolant replacement is prohibited. If you try to change the fluid, the Tesla radiator/coolant will degrade and show weird behavior. As a short-term solution, this action might seem easy and problem-solving but the coolant will break down chemically and you’ll later require to change the whole cooling system. And that will cost more than thousands of dollars.

If the coolant seems to be leaking or showing an error message on the screen, then it’s better to contact Tesla Service. The Tesla Service Center will charge around $200 – $900 based on the damage and difficulty of the labor. The cost will be less if the labor is easy. The coolant will last for life and won’t require replacement. Tesla uses G-48 ethylene-glycol fluid in battery coolant that contains 60% ethylene glycol and 40% purified water to ensure ideal operation. Tesla cars don’t have a liquid cooling system in the battery.

The Quantity of Coolant in a Tesla

Tesla cars contain up to 17-19 liters of coolant in the battery system, with some cars containing 11 liters. The amount of coolant can vary based on the manufacturing date of the car. The coolant is a G-48 ethylene-glycol fluid that helps control the battery’s temperature and optimize its performance. The coolant is circulated through the battery system by a pump and fan to ensure proper heat transfer. It is important to note that the coolant should not be replaced by the owner, as it requires specialized equipment and knowledge.

You Can Check Battery Coolant Level In Tesla

Tesla owners can check the battery coolant level at home, which takes around 5 minutes to do. The procedure involves a few steps, but it is not complicated. Here is a step-by-step guide on how to check the battery coolant level in a Tesla:

1. Use the key fob, mobile app, or touchscreen to open the frunk.
2. Pull up the maintenance panel upward after releasing the clips. The tiny clips hold the panel into the top section.
3. Unlock the clips on the HVAC intake trim panel to expose the 2 hidden bolts.
4. Use a 10 mm socket or ratchet wrench to remove these bolts. You can also use a screwdriver if it doesn’t have a wrench.
5. Remove the carpet from the cabin storage area. You’ll find 2 similar bolts.
6. Take these out using the same tool.
7. Detach the latch trim panel using a pry bar. With the 10 mm ratchet wrench, unscrew the 2 bolts. Ensure to remove the wiring harness plug.
8. Take out the bolt near the brake location.
9. Use a pry bar or your hand to pull out the front tub. Detach the cabin intake trim panel.
10. Wear gloves and use cloth on top to remove the cap of the coolant.
11. Get a dipstick and insert it inside the coolant tank to understand the level of fluid.
12. After knowing the level, put everything back in place.

It is important to check the battery coolant level regularly to maintain the performance of the vehicle. If the coolant level is low, it can cause damage to the battery, and the vehicle’s performance can be affected.

Tesla recommends that owners follow the maintenance service intervals to ensure the vehicle is running efficiently. Checking the battery’s charge level, tire pressure, and exterior lights are some of the essential maintenance checks that should be done regularly.

If an owner is not comfortable performing maintenance checks, they can take their vehicle to a Tesla service center. However, it is essential to note that some maintenance checks, such as battery coolant level checks, can be done at home.

It is worth noting that DIY Tesla battery coolant replacement is not suggested, and it can void the warranty. If a Tesla owner experiences a low coolant warning on the touchscreen, it is recommended that they take their vehicle to a Tesla service center.

Overall Thoughts

Based on the information gathered, it is clear that Tesla does not recommend replacing the battery coolant. Attempting to do so may have negative impacts on the vehicle’s performance and may even cause harm. Coolant degradation is a complicated process that should not be taken lightly. It is recommended that owners prioritize regular maintenance such as preconditioning the battery, to ensure that their vehicle performs at its best. Taking care of the battery and other components will ensure that the car remains efficient, safe, and reliable in different weather conditions.

Frequently Asked Questions

What Type of Coolant is Recommended for Tesla Electric Vehicle Batteries?

Tesla electric vehicle batteries require a specific blend of G-48 ethylene-glycol coolant (HOAT) fluid.
