So recently my water pump begin to make some very serious noise and today I attempted to change it out to a new one. When putting the new one on the block, I put a thin layer of gasket sealer on the pump itself, then I put the gasket which came with the pump, and put that on the prepared and smooth surface of the block.

After I put everything back together I was surprised to see that the pump was leaking even before I started the car up. I didn't have time to fix it so I intend to do that tomorrow.

If I'm not mistaken there are four bolts which hold on the pump to the block, And one which holds the pipe to the pump and goes into the block. Does that sound right? There seems to be an extra hole in the new pump but I wasn't sure if I had lost a bolt.

I'm not sure if I can buy a gasket by itself. But when I redo the job tomorrow I would like to wind up with no leaks at all.

Thanks for all your help.
