How to Replace Tesla Coolant?
3 Answers
For older vehicles, the following pipeline conditions need to be checked during replacement: inspect the coolant pipes for cracks or signs of fluid leakage. When replacing with new coolant, ensure the old coolant is completely drained, then flush the pipes with clean water by pouring water into the reservoir. When adding new coolant, directly pour approximately 3.5L of antifreeze into the reservoir, and stop filling once the liquid level reaches the upper limit MAX mark.
I just replaced the coolant in my Tesla, and the whole process required careful operation. First, park the car on a level surface and ensure it's completely cooled for several hours to avoid hot fluid splashing. Then, disconnect the negative terminal of the 12-volt battery—this is a critical safety step. I gathered tools like wrenches and a large container, opened the drain plug under the coolant reservoir, and let the old fluid slowly drain into the bucket. Tesla coolant is typically glycol-based, which is toxic and harmful to the environment, so I wore gloves and took the old fluid to a recycling point. Next, I flushed the system twice with distilled water to remove any residual impurities. I prepared Tesla-certified new coolant, such as the G48 model, making sure to get the right brand to avoid damaging the motor. Slowly pour the new coolant into the reservoir until it's full, which takes about 4-5 liters, then start the vehicle and let the fans run for a few minutes to remove air bubbles. The entire process took over an hour, with material costs around 120 yuan. Finally, I checked the system for leaks and ensured functions like the air conditioning were working properly. It's recommended to replace the coolant every 4-5 years and regularly monitor the fluid level.
As a frequent visitor to repair shops, I've learned a lot from changing Tesla coolant. Safety first means disconnecting the battery and high-voltage contactors to prevent electric shock. Using specialized vacuum equipment to drain the old fluid is efficient, but DIYers can opt for the simple drain plug method. Flushing thoroughly with two cycles of distilled water is crucial. Tesla-specific coolant must be low-conductivity type to avoid corroding battery components. Replacement interval is roughly every 50,000 km or 4 years. DIY costs less but carries higher risks. Improper air bubble removal may cause overheating issues; using wrong fluid voids warranty. Required tools include containers, funnel, and protective gear, with material cost around 100 yuan, while shops charge 200-300 yuan for full service. Regularly check headlights or cooling fans for abnormalities - this maintenance extends vehicle lifespan.
