Top hose, no problem compared to the bypass hose on top of the water pump. The water pump just started to weep, so to change it :
Drain AF, the bottom radiator hose is easy. Air inlet off..
Remove the 3 bolts holding the top shroud, there are staples holding the bottom to it
Remove the belt and alternator, then the curb side radiator brace
Disconnect the oil fill tube and the top radiator hose
Take off the fan, 36mm open end and unscrew the hub part way, you may need j41240 holding tool to loosen it. Now take the fan off the hub. I put some some 1/4" foam against the radiator to protect it, then unscrew the fan hub completely and take the hub out. If you rest the blades against the foam, the upper fan shroud can now be wiggled out.
Now you can change the water pump, the bypass hose, or thermostat.... The bypass hose is a special snowflake, ac delco 12558968, the rest of the pieces were easy to get.
Hope this helps anyone who wants to do this job, winter jobs, so you can cruise with less worry...
