You can check the water pump by taking off the serpentine belt and spinning the pulley on the water pump, if it has any play in it is time for a new one. Shoulda just replaced that while you were doing the coolant elbows. They're relatively inexpensive depending on where you buy them.
Yes it was my stupid water pump. Water Pumps fail with some regularity--you can expect to replace yours sometime before 100,000 miles
Like my Coolant Elbow the thing was left un cared for and it sits at 167,000 miles for an 02. Thanks again everyone for the awesome help
