Coolant bubbling in the expansion tank typically indicates the presence of air or gas in the cooling system, often caused by a blown head gasket, a cracked engine block, or a damaged cylinder head. This can allow combustion gases to enter the cooling system, leading to pressure fluctuations and bubbling. Additionally, overheating or low coolant levels can exacerbate this issue. It's essential to diagnose and address the underlying problem to prevent engine damage.
