How Often Should I Top-Up My Coolant?

Regularly checking and topping up your coolant is essential for maintaining proper levels and preventing engine overheating. We recommend checking and topping up your coolant at least every 12,000 miles or as indicated by your vehicle's manufacturer. Consistent monitoring helps ensure the protection of your engine against excessive heat.
