Hello I have a 2000 deville motor has around 100k miles it's been swapped before to this one anyways the belt broke and it ruined the tensioner pulley the smaller one and the bigger now this is how far I've gotten I have the tensioner off and everything in the way so far I know I just have the water pump area to go I know I have to have a special tool and I have it only problem I am having is that bigger pulley it looks like it has a trex head it's rounded and looks like it I'm not vary sure but that's how it appears now how do I go about removing that ? Do I need a special pulley removeal tool ? Is there any other way special trucks any more work I'd have to do in order to get it off ? I'm kinda knowledgeable when it comes to cars I can some mild work on them so is this something I should keep going with or have someone else do it ? Please any feed back would be much appreciated
