Polestar 2 High Voltage Battery Coolant Service

Vehicle: 2022 Polestar 2 Long Range Dual Motor

My 2022 Polestar 2 Long Range Dual Motor is approaching 3 years old and has about 45,000 miles on it. I'm wondering about the high voltage battery coolant. Is this something that needs to be flushed or replaced at a certain mileage/time, similar to an engine coolant in a gas car?

What's the recommended interval for this type of service? Also, is this a DIY job that I can tackle in my garage, or does it require specialized tools and knowledge, making it a dealer-only service? Any insights would be greatly appreciated!

ClearTheCode admin answer:

Maintaining your Polestar 2's high voltage battery coolant is crucial for the longevity and performance of your electric vehicle. The battery thermal management system ensures the battery operates within optimal temperature ranges, preventing degradation and maximizing efficiency.

  1. Service Interval: Unlike traditional internal combustion engine coolants, EV battery coolants often have much longer service intervals. For the Polestar 2, the high voltage battery coolant is typically designed for the life of the vehicle or for very extended periods, often exceeding 100,000 miles or 5-7 years, before a check or potential replacement is recommended. Always refer to your specific owner's manual or Polestar service schedule for the most accurate information.
  2. Specialized Coolant: Polestar EVs use a specific type of coolant, often a specialized long-life, low-conductivity fluid. Using the wrong type can cause serious damage to the high voltage system.
  3. DIY vs. Professional Service: This is not a recommended DIY job. Here's why:
    • Safety: Working with high voltage systems requires specific safety protocols and training to avoid serious injury or death. The system must be properly de-energized.
    • Specialized Equipment: Flushing and refilling the system correctly often requires vacuum fill tools to prevent air pockets, and diagnostic tools to properly cycle the system and monitor temperatures.
    • System Complexity: The battery cooling system is integrated with other thermal management components, and improper service can lead to efficiency loss or component failure.

When to See a Shop: If your vehicle displays any warning lights related to the cooling system, or if you notice unusual noises or performance issues, take it to an authorized Polestar service center immediately. For routine checks, follow your vehicle's maintenance schedule. A qualified Polestar technician has the necessary training, tools, and genuine parts to perform this critical service safely and correctly.
