It can be the cooling fan, clogged radiator or a blown head gasket. I would go over this video and guide to see what is going on. When the engine is overheating can you hear the cooling fan come on?

Also, check for a plastic bad stuck in front of the radiator. Please go over these guides and get back to us.
