How to replace a water pump on a 2004 ford taurus

DON'T run the engine for too long if your getting steam. That will risk over heating problem putting other engine parts at risk of damage.
How are you testing for circulation? Coolant systems are usually pressurised when the engine is running so a pressure leak somewhere in the system could be the problem, The bleeder valve could be part of that.
Try checking the basics first. Do you have enough coolant in the system? When the thermostat opens, the coolant level can drop.
Check the routing of the belt for the water pump. Sometimes if the belt is set up wrong it can spin the pump backwards causing issues.
There are also times where a new part can be faulty. I had this happen with a new wheel bearing that lasted just 150 miles before it started making noise like it was going to fail.

check to see if the radiator and A/C condenser are clear of airflow obstructions (damage, excessive leaves and dirt, etc). Check to make sure that the electric fans are running. There are 2 speeds. As it warms up, it should go slow, then when it gets hot, the fans should go to high speed. Check also to see if radiator is blocked up. It should be at engine temp on one side, and it should be cooler, but still warm, on the other side. Neglected coolant causing rust and debris blockages in the radiator are common to these cars. If the coolant is rusty and orange/brown, it may also indicate a failing water pump

Did you recently have a transmission fixed?
If so it sound like the drive plate bolts were not applied with Loctite.
Maybe a oil viscosity problem if not a transmission job.

If you have a serpentine belt, It drives everything, including the water pump.
