While you don’t need to do it often, checking and refilling the car’s coolant is a vital part of auto maintenance. This important fluid helps your vehicle run properly by supporting its cooling system. If you’re unfamiliar with this liquid, use the guide below to find out what it does and why maintaining it is essential.

4 FAQ About Car Coolant

What does coolant do?

This fluid keeps your car’s engine at a regulated temperature. It prevents costly damage and excessive wear by keeping the auto parts from freezing in cold weather and overheating while in use. The fluid also protects the engine and other elements of the cooling system from corroding.

Is all coolant the same?

Coolant isn’t universal, as each vehicle requires a certain type of fluid based on its cooling system. Always use the correct product to prevent internal corrosion and gasket leaks. Some manufacturers void their warranties if problems arise from incorrect fluid usage.

How often should it be changed?

Coolant will become acidic over time, losing its effectiveness. Flush and replace the fluid periodically—this frequency depends on your vehicle’s recommended auto maintenance schedule. Some manufacturers advise a change every 30,000 miles, but many modern cars can go for longer intervals.

Why should I monitor my car’s coolant level?

Check the fluid level at least twice a year, regardless of the manufacturer’s suggested replacement timeline. The inspection will allow you to ensure the level isn’t dangerously low. If you’re refilling the fluid frequently, there’s likely a leak or broken part in the system that needs immediate attention from a professional.
