I am in the process of changing my water pump. I have removed all the bolts, the power steering bracket, etc. However, the pipe that goes into the top of the water pump (I included pictures, sorry for the poor quality it was night time) will not budge, and i am clueless as to how to remove it. Any input will be greatly appreciated, thanks!!

 

i had the same problems i just kept spraying it with wd-40 till it finally budged i say it took me a good 45 mins to get it off, i had to take a hammer and pointed chisel and hit the lip till it came off good luck with it, its a pain
