In the process of removing the water pump removed what i thought were all the bolts but it won't come off. it pivots side ways left and right, I put my finger on the bottom of the water pump and i feel a bolt that it may be pivoting on but it is impossible to get a wrench to for the pulley is in the way. Over the years ive changed water pumps with bolt on pulleys, im not familiar with a press on type of water pump pulley I would like to know if that is indeed the case. It is the same type of pulley as the tensioner pulley in which i removed by removing the bolt. But this pulley does not have a nut , it has a round ****. Any help would be greatly appreciated. And if so would a normal three prong wheel puller do the job. Thanks

 

i think you have to use a "barrel" puller,its small and round comes in two pieces you have to put one side on top of pully insert threaded bolt onto top of pully,put other side on then slide collar down assembly and tighten bolt to remove pully,it helps to have some extra hands...
