      Water Pump Removal Problem.

      I'm trying to change the timing belt on my 2004 Chevy Aveo and I'm having problems with the water pump. I've removed the 3 screws that keep it in place and I also removed the the tensioner pulley, idler pulley, and the camshaft wheels to remove the inner cover; the water pump simply refuses to come out. I tried turning it with the 41mm water pump wrench and nothing. I tried WD-40 and that didn't work. I tried pulling it by hand and nothing. Is there anything else I can try to remove the water pump?

      the Oring is probably seized in there pretty good. your going to probably have to turn it back and forth with the 41mm, and pry out on it at the same time until you wiggle or work it out of there.

      I would use the pump drive as a pull. Put a long screwdriver under it, the end on a block of wood, and pull on the handle. Instead of WD-40 shoot some purple magic (alkaline detergent), that can make the o-ring slippery
      Please do not power off, firmware update pending.....

      I tried the pulling and turning technique but still nothing, its on there like cement. I haven't heard of Purple Magic but ill give it a try and see if that helps.

      Maybe it's time to take some pictures. We might be able to see something that you may have missed.


      At least does it rotate?

      The only thing that rotates is the pump drive wheel. When I try to move the water pump body with the water pump wrench it doesn't turn. I'll be uploading some pictures in few moments.

      Here are a few pictures of the water pump I'm trying to take off. It's still on there pretty good.

      this might sound a little brutal, but get a soft faced hammer or Rubber mallet, and tap on the Water Pump Sprocket until the pump drops out of the Volute.

      I would agree, the other thing you can do is get a big flat blade screw driver and drive in that grove upper right. The other option is to ice chill the pump and hope that allow will shrink faster than the steel.
