Yes, it came off clean as a whistle and the new one slid in perfectly, the old gasket was still in one piece leaving no trace of gasket to clean off the face, obviously the new one came with the same design of gasket, sort of rubberised coating on a springy metal form.Is your water pump the two part one with the backing plate?
Only bought the main pump, didn't get the rear section, much more involved job to change anyway.
Getting the new auxilliary belt on reqd me finding my extra pair of hands in the form of the Mrs, had to enlist her to keep pressure on the tensioner release whilst i did a fair impression of an octopus trying to keep the belt on track on all those pulleys, once again reminded me that you would not want be trying to fit said belt on the hard shoulder of a busy motorway by torchlight, hence new belt now.
