Hello I'm Neal and I am here to help resolve your issue. If I cannot help I will opt out and refer your question to another expert.

 

That is almost certainly just a bad radiator cap. Replace the cap and it should resolve the issue. Until then it should be ok as long as it does not run hot, but I would get a new one asap.
