Is Coolant Bubbling Bad

Check the radiator cap seal or just replace the radiator cap (borrow one from a friend to test?) Originally Answered: Is it bad if the coolant bubbles in the reservoir? Yes. It means there is air in your cooling system, and this is always a bad thing.

How do I get rid of bubbles in my coolant system?

When the engine warms up and the coolant starts to circulate, slowly add more until it is completely full. Fill the overflow tank, also known as the reservoir tank, with coolant. Keeping the overflow tank full helps to remove air bubbles and also works to ensure that your radiator will always be full.
