I have 2GM an it was quite simple take pump off dismantle, replacement seals and rebuild. As long as shaft is not damaged where water seal rubs, in the end local engineer put mine back together as I had no clean area to reassemble.
Still if you can take it off and take it to the man it should save a chunk on repairs.
