When I drive for a short period of time, my coolant starts overflowing and boiling. I’ve replaced the thermostat, my radiator was changed 3 months ago, and my car does not overheat. Even at half tank of coolant it’s start flowing out of radiator cap which I also replaced. Can it be my radiator clogged? Or is everyone's worst nightmare a gasket leak? Help!

Hi,

If the engine isn't overheating, it sounds like compressed air may be getting into the cooling system from a failed head gasket.

Do me a favor. Take a look through this link. It explains the most common symptoms related to a faulty head gasket and how/what to check.

Let me know.

Take care,
