2019 Tesla Model X Coolant Capacity & Type

The 2019 Tesla Model X holds approximately 16.9 quarts (16 liters) of coolant.

Quick Answer

• Total Cooling System Capacity: Approximately 16.9 quarts (16 liters)
• OEM Coolant Specification: Tesla G-48 (Blue/Green HOAT - Hybrid Organic Acid Technology)
• Mix Ratio: 50/50 Pre-Diluted

Capacity by Engine Option

The Tesla Model X, being an electric vehicle, does not have traditional "engine options" in the internal combustion sense. However, its cooling system manages various components, including the battery, motors, and power electronics. The total capacity listed above applies to all 2019 Model X configurations.

Flush Interval

Tesla generally recommends checking the coolant every 2 years or 25,000 miles, whichever comes first, and replacing it every 4 years or 50,000 miles for normal duty. For severe duty, such as frequent towing, extreme temperatures, or track use, it is wise to consider flushing and refilling the coolant more frequently, possibly every 2 years or 25,000 miles.

How to Refill & Bleed

Refilling and bleeding the cooling system on a Tesla Model X is a more complex procedure than on a conventional internal combustion engine vehicle due to the integrated thermal management system. It is generally recommended to have this service performed by a Tesla service center or a qualified independent specialist with the appropriate diagnostic tools.

If you are performing this at home and are experienced with EV high-voltage systems (which can be dangerous), consider the following general steps. Always consult the official Tesla service manual for your specific model year before attempting any cooling system work due to potential high-voltage hazards.

1. Safety First: Ensure the vehicle is powered off and in "Service Mode." Disconnect the 12V battery and take appropriate precautions for working with high-voltage systems. If you are not trained in high-voltage safety, do not proceed.
2. Drain the System: Locate the drain points for the various cooling loops. There are typically multiple drain points for the different circuits (battery, drive unit, and cabin heating/cooling). Drain the old coolant into a suitable container for proper disposal.
3. Refill: Use only the specified Tesla G-48 coolant (pre-diluted 50/50). Slowly add coolant to the reservoir(s). The Model X often has multiple reservoirs for different loops.
4. Bleeding: The Tesla Model X cooling system is sophisticated and relies on electric pumps and valves. It does not typically have simple bleed screws like traditional vehicles. Bleeding is often performed using the vehicle
