Run with no belt?

2003 Durango SLT 4x4 4.7
I have a strange sound coming from the engine compartment that I think is coming from the water pump. Sounds kind of like a scraping sound only when revving the engine. When Idling it doesn't make the sound, but when giving a little gas it increases with rpm's and doesn't matter if it is in Park, 1st, or neutral. The same time I noticed this sound I also noticed antifreeze leaking where the lower radiator hose connects on the motor side. I then checked the coolant dipstick and it was bone dry, so I filled it back up.
Tomorrow I'm going to replace the hose and also the water pump to hopefully fix the noise and the leak. While I have the belt off, can I start the motor for just a few seconds to check if that is where the noise is coming from? This would confirm that the noise was coming from one of the devices that the belt is connected to if the noise isn't present with the belt removed.

Thanks for the replies, but I didn't have to run it without the belt on. When I took off the belt, I could jiggle the pulley on the water pump all around and it made awful sounds when I spun it. It was probably a few miles away from just blowing apart. I replaced the water pump and the lower radiator hose. All is good now and she runs like a charm! Now to get the Ram running so I can sell the Durango.

Is the 4.7 a dry sump with an external pump? If not the oil pump will be running and overheating is the worry. It is really a mute point as the OP has found his problem but this kind of miss info is not good to put out there.

The Durango has been an awesome vehicle and has never left me stranded or stuck. I just have 2 other vehicles that are older and less reliable, but I'm ready for some adventure. That and I need the cash.
