Tesla Model Y · 2020–2025
Tesla Model Y Fluid Types and Capacities
The specification is not the same across every year we cover, the table below shows exactly where it changes.

Has the Tesla Model Y fluids specification changed by year?
| Model years | Transmission | Coolant | Brake |
|---|---|---|---|
| 2025–2025 | Drive-unit reduction gearboxes are lifetime-fill | Tesla-specific sealed battery/powertrain coolant loop, no owner service | DOT 3 brake fluid; test for contamination every 4 years |
| 2020–2024 | Front/rear drive-unit reduction gearboxes use lifetime-fill gear oil, no scheduled change | Tesla-specific battery/powertrain coolant loop, filled for life, no owner service or top-up (opening the system is a service-center job) | DOT 3 brake fluid. Tesla: test for contamination every 4 years, replace as needed |
Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.
Full specifications by generation
The fluids on a Tesla Model Y is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.
Tesla Model Y fluids: common questions
What transmission fluid does a Tesla Model Y take?
- Drive-unit reduction gearboxes are lifetime-fill. Transmission fluid specifications are not interchangeable. Friction modifiers differ between them, and the wrong fluid causes shudder long before it causes failure.
What coolant does a Tesla Model Y use?
- Tesla-specific sealed battery/powertrain coolant loop, no owner service.
What brake fluid does a Tesla Model Y take?
- DOT 3 brake fluid; test for contamination every 4 years.
