I have a 1998 Bonneville SLE that leaked all the radiator fluid yesterday, thought it was coming from the water pump. The water pump had a squeeling noise but after filling the radiator with water to see where it was leaking, the leak was coming from a black pipe (90 degree bend) just above the water pump behind the idle pulley for the serpentine belt. What is this pipe called and how do I replace this pipe, what items need to come off the car to replace.
Thanks for any help!!

That is a coolant elbow. They are available from the Help section at the local auto parts stores. A common issue. Have you done the intake gaskets and dex-cool flush?
