What does it mean when your engine coolant is bubbling?
Bubbling indicates rising air pressure in the cooling system, which is a sign that the flow of liquid is blocked by a pocket of air. One of the most common causes is a blown head gasket, in which the air pressure inside the cylinder heads is transferred to the cooling system.
What drives the coolant pump?
The cooling liquid absorbs the heat from the engine block and cylinder head and releases it into the ambient air through the radiator. Standard mechanical water pumps are driven directly by the engine. When the engine is running, they pump coolant continuously even if cooling is not required.
