Water Pump Removal Problem.

[2010AveoLT]

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.

I wouldn't do that for the simple fact that you could damage the mating surface that the o-ring uses to seal the pump to the block.

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.

Before my aveo I used to have a "Chevy corsa pick up 1999", it uses the same water pump as aveos. I literaly had to chisel it to pieces bit by bit as it was really stuck in there! luckily no damage to engine block occured! I didnt replace the water pump when I should have.

well, I got fed up with trying to hammer it and pull it off so I decided to use a drill to drill a hole in the middle and try breaking it piece by piece. So far I'm getting some very good progress; I've bought a dremel tool to help cut the pump into pieces.

Yep... thats more or less the way I had to do it. It takes a couple of hours but in the end it will give in. All I recommend is patience as if you get angry (and you will) you could damage the engine block or other parts.

Finally got the corroded P.O.S. out.

WOW, that Pump was Virtually RUSTED to the Block! its a good thing you're replacing it then!

Congratulations! I am impressed that it adhered to the block. I would defiantly flush your water system. And take some light sand paper to the block to make sure that mating surface is clean.

Great pics! I think Ive got some old pics somewhere. Will have a look for em.

Well, ain't that funny? After one problem is done, along comes another one. I've replaced the water pump, put on a new timing belt, and did all the aligning correctly. Placed everything in order; double and triple checked that all the connections were on and made sure nothing was loose, and finally added new coolant. Just as I was about to turn the engine over, Nothing. Car won't turn on. I crank it for 5 seconds and it doesn't want to turn on. I can hear the fuel pump priming, but it wont turn on. I've had the battery off for about 2 months since their was no point of using the car since It took forever to get the water pump off. Is there something I'm missing?

Thanks in advance.

usually after that long of a time out, the battery needs charging. Mine did when I did the shocks and body repairs. Just take it to auto shop and they are kind enough to charge it for you.
