The 2025 Tesla Model Y holds approximately 11-12 quarts (10.4-11.4 liters) of coolant in its primary cooling system.
Quick Answer
- Total Cooling System Capacity: 11-12 quarts (10.4-11.4 liters)
- OEM Coolant Spec: Tesla G-48 (Blue, HOAT - Hybrid Organic Acid Technology)
- Mix Ratio: 50/50 Pre-Diluted (do not add water)
Capacity by Engine Option
Unlike traditional internal combustion engine vehicles, the Tesla Model Y utilizes an integrated thermal management system that cools the battery, motors, and power electronics. The coolant capacity remains consistent across all 2025 Tesla Model Y variants (Rear-Wheel Drive, Long Range, Performance).
| System | Approximate Capacity (Quarts/Liters) |
|---|---|
| Primary Cooling System (Battery, Motors, Power Electronics) | 11-12 Quarts / 10.4-11.4 Liters |
Flush Interval
Tesla recommends checking the coolant level periodically and replacing the desiccant bag in the coolant reservoir every 6 years or 75,000 miles, whichever comes first. A full flush and replacement of the coolant is generally not specified by Tesla as a routine maintenance item, as the system is designed for a long service life with minimal degradation. However, if the system is opened for repairs or if contamination is suspected, a full flush and refill would be necessary.
- Normal Duty: 6 years or 75,000 miles (desiccant bag replacement)
- Severe Duty (e.g., frequent towing, extreme climates): Consider inspecting the coolant more frequently and performing a flush if contamination or deterioration is observed, although this is not explicitly outlined by Tesla.
How to Refill & Bleed
Refilling and bleeding the cooling system on a Tesla Model Y is a critical process that often requires specialized tools and knowledge. It
