While the concept of water pumps is the same across brands the method of how the impeller sits on, or is attached to the shaft may be different. This pump has a slotted shaft and the impeller has a screw that sits in the slot. To remove it I simply use my needle nose Vise Grip pliers. It just pops right out and could not be any simpler.


Some pumps use set screws or c-clips. Impellers with c-clip retaining rings will require a set of c-clip pliers. It's always good to know what your pump looks like before taking it apart so you can have the right tools on hand. Most engine manufacturers and pump makers have on-line parts manuals that will show an exploded view and will allow a sneak peek into the inside of your pump before you open it up..
