2017 Tesla Model X Coolant Capacity & Type

The 2017 Tesla Model X 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 deionized water and Tesla G-48 coolant concentrate (pre-mixed coolant is also available).

Capacity by Engine Option

All 2017 Tesla Model X variants (75D, 90D, P100D) utilize the same primary cooling system and thus have the same coolant capacity of approximately 11-12 quarts (10.4 - 11.4 liters). It's important to note that Tesla vehicles have multiple cooling circuits, including those for the battery, power electronics, and motors. This capacity refers to the primary cooling system for the powertrain.

Flush Interval

Tesla recommends checking the coolant every 2 years or 25,000 miles (40,000 km), whichever comes first, and replacing it if necessary. However, for severe duty conditions (e.g., frequent towing, sustained high-speed driving in hot climates, or track use), it's advisable to inspect and potentially flush the system more frequently, perhaps annually or every 12,500 miles (20,000 km).

How to Refill & Bleed

Refilling and bleeding the cooling system on a Tesla Model X requires specific procedures to ensure air is properly purged and all components are adequately cooled. Due to the complexity and multiple cooling loops, it is highly recommended to have this service performed by a Tesla Service Center or a qualified independent specialist.

For those with advanced mechanical skills, the general steps involve:

1. Safety First: Ensure the vehicle is powered off and cool to the touch. Wear appropriate personal protective equipment.
2. Drain: Completely drain the old coolant from all accessible drain points. This may involve multiple drain plugs for different circuits.
3. Flush (Optional but Recommended): If the old coolant was contaminated or discolored, a thorough flush with deionized water is recommended until the water runs clear.
4. Refill: Slowly add the specified Tesla G-48 50/50 coolant mixture into the primary coolant reservoir. Do not overfill.
5. Bleeding: This is the most critical step. Tesla vehicles often require a specific diagnostic tool to activate the electric coolant pumps and open various valves to properly circulate coolant and purge air from the system. Simply filling the reservoir and running the vehicle will likely not adequately bleed the complex system. The process typically involves cycling the pumps and monitoring coolant levels and temperatures via the diagnostic interface.

Common Cooling System Issues

Owners of 2017 Tesla Model X vehicles may experience or should be aware of several cooling system-related issues:

• Coolant Pump Failure: Electric coolant pumps can fail, leading to overheating of specific components (battery, motors, or power electronics) or the entire system. This often triggers dashboard warnings.
• Coolant Leaks: Leaks can occur at hose connections, O-rings, or from components like the battery cooling lines or heat exchangers. Due to the high voltage nature of the vehicle, coolant leaks near electrical components can be particularly problematic.
• HVAC Performance Issues: The cooling system is integrated with the HVAC system. Issues with insufficient cabin heating or cooling can sometimes be traced back to problems within the coolant circuit.
• Battery Thermal Management Issues: The battery pack relies heavily on the cooling system to maintain optimal operating temperatures. Failures here can lead to reduced battery performance, range, or even damage if not addressed promptly.
• Corrosion/Contamination: Using incorrect coolant types or neglecting flush intervals can lead to corrosion within the system or contamination, potentially clogging passages and reducing cooling efficiency.
