The recommended interval for checking and replacing the coolant in an electric vehicle (EV) varies depending on the make and model, but general guidelines are as follows:
- Checking Coolant: The coolant system in an EV should generally be checked at least every 10,000 miles or annually for level and condition; this is typical in some models like the Ford Lightning, which suggests annual or 10,000-mile checks to ensure proper coolant level and condition.
- Replacing Coolant: Many manufacturers recommend replacing EV coolant every 80,000 to 150,000 miles or every 5 years, whichever comes first. For example:
- Hyundai and Kia recommend changing coolant around 80,000 miles.
- Mercedes-Benz suggests a coolant replacement schedule near 124,000 miles.
- Some EVs, such as the Tesla Model 3, reportedly do not require coolant changes at all during the vehicle’s life.
- General Industry Recommendation: A common broad guideline is to change coolant every 150,000 miles or five years, as noted for electric vehicles with thermal management systems, similar to conventional vehicles.
Because EV coolant systems are usually sealed and require specialized tools and fluids to service, it is recommended to have the coolant checked and replaced by professionals and to follow the specific vehicle manufacturer’s guidance to avoid voiding warranties or damaging the battery system. Checking for leaks and monitoring battery performance during coolant inspections is also important for safety and longevity.
In summary, you should have your EV coolant level checked about once a year or every 10,000 miles and replace the coolant every 80,000 to 150,000 miles or approximately every five years, depending on your vehicle manufacturer’s specific recommendations. Always consult your EV’s owner manual for the most precise schedule.
