Stubborn Water Pump
Hey everyone. I'm currently working on a motor before I put it into my shell. I'm trying to remove the water pump, but the silicone seal has got it held up pretty tight. I tried using a pry bar set behind the water pump shaft, leveraged off the power steering pump bracket. After maybe like 10 solid strikes with a heavy mallet the pump was still in place it didn't look like it moved at all. Is there anything you guys use to soften up the silicone seal?

I usually give it a few good whacks with a rubber mallet. You removed the PS bracket, correct?

check to make sure you got all the bolts?

I had the same issue, ended up taking a knife and cutting into the glue gasket and trying to pry it off in couple areas. Carb cleaner might help eat away the gasket.

I also broke my old water pump in one area trying to pry it. I decided against just doing that incase the block would break too...

Try a block of wood and a hammer...I would avoid stickng things betwen the pump and block or it might gauge it and might notseal correctly

The bracket that holds the power steering pump is off. The actual piece that bolts to the block is still on. I'm thinking its made out of iron. I rest my pry bar on that iron piece. That way any impact damage does not hurt the block. The tip of the pry bar, I placed behind the flange that the water pump pulley bolts to.

The engine is on a stand. I didn't mention that in the first post.

Swiss I did try using a rubber pellet filled mallet. I started striking on the outer side of the water pump. I stopped that technique once I made a dent into the water pump aluminum. I just caught the outer edge of one of the bolt holes, so I don't think that dent will mess up the pump.

The pump itself has 62,000 miles on it. The shaft doesn't have any play in it, and it spins well with hand pressure. I just wanted to get the pump off to check the condition of the blade before I drop the motor into my shell. I'm thinking maybe I should just leave it as is.

What do you guys think? I wasn't having an issue with it before I pulled the motor out of the donor car. I'm starting to think I might make things worse by trying to be thorough.
