There could be combustion gas in the cooling system. A block test can answer this question, there are affordable ones at the parts house or harbor freight. Using the fluid if it turns from blue to green you have a bad head gasket. Just because it isn't overheating visibly doesn't mean it's not overheating.

Yep I agree with KRAKENAUTO, here is a video that can help us confirm the blown head gasket.
