Common questions
Why does an EV need coolant?
The battery works best in a set temperature range. Coolant carries heat away during driving and fast charging and keeps cells from wearing early.
How often is service needed?
Many makers say every 4 to 8 years or 100,000 miles. Check the owner's manual for your car's schedule.
Is it safe for a regular shop?
Only if the shop has trained techs and the right tools. High-voltage parts can be dangerous, so ask about their EV training.
