Steam coming from lower radiator hose

[72WiscSub]

350 engine.

I have steam coming from my lower radiator hose where it connects to the water pump. No fluid leak just steam. My wife noticed it last week when she was out driving it. She stopped at a friends and and said white stream/smoke was coming out from the engine bay. Not a ton but enough to notice. When she got home I could not see anything.

I just got back from a 10 minute drive and when I popped the hood I noticed a bit of steam coming from the lower radiator hose.

The clamp seems tight. Is it normal for the fluid to get warm enough to cause steam or do I have a bigger problem? How do I check to see if the water pump is bad?

Any thoughts would be very helpful.

Thanks
