What happens if your antifreeze tank is too full?
If the overflow tank is too full, the coolant antifreeze mix can spill out and make it look like a leak. If this is the case it should only leak a couple of times before correcting itself. If it continues, you may have a leak. Use K-seal to quickly remedy the issue. Find your nearest K-Seal supplier.
