Hey all. Bit o' a problem. When car is idling, temp stays normal, but no coolant can be felt in either radiator hose. Upon revving the engine a bit, the upper gets hot, and still no coolant fills either hose. Mind you, the radiator has a hairline crack in the top, and steam shoots out, but only when rpm is increased, and instantly, I know rad. Needs replaced, but surely the water pump isn't working either, what you guys think?

you are not building pressure up and low on fluid

You might be right. I flushed the system, and put almost a full bottle of coolant back in, maybe its not enough.. I know I wouldn't build pressure with the radiator crack, but with as much coolant as I put in, I figured I would be able to feel it in the hoses.. coolant does in fact drip more around the water pump housing as rpm goes up... maybe its just the gasket, not the pump itself...
