I am putting in an electic water pump and i was wondering if it was necessary to plug the hole in the block where the waterpump shaft used to be. Or can i just leave it? Thanks in advance.

 

Not necessary, but it can be done. There is a how-to floating around here somewhere explaing just how to do it. But if you are not getting into the timing cover for any reason i would just leave it.

 

I just left it, it just spins with no load.

I left the hole in the block but I jb welded the hole on the timing cover.

 

I have done it both ways. I had my last cover welded up and my new one has the shaft going round with no load.

 

I think ill just leave a hole there if it doesnt hurt anything. Im not going to leave the shaft in their just to freewheel.

 

I pulled the drive (since I use a Cloyes dbl/roller), but I found that a half dollar fits perfectly, and then get some aluminum repair stuff and aluminize it into the cover

It will freak the next owner out when he tears it down

 

From what I understand you can have it both ways, if you are going to remove the shaft then you will need to plug the hole and if you leave the shaft to free spin then you should be fine without pulling the timing cover. With the shaft left in, it makes the install much quicker, and the shaft blockes the hole in the cover. If you remove the shaft and you will need to block it off! If I am wrong someone please correct me but I am pretty sure I am right on this one.

 

Why would you need to? What could it hurt? Anyone have more input?

 

If you remove the shaft and not block the now wide open hole in the timing cover. Then you will be posting about the oil leak developed after doing a waterpump install. Most pumps come with one plug and that is for the WP housing. If you remove the shaft that is currently pluging a hole in the timing cover then you will need to plug it.

 

I dont think you understand what im saying. Not the hole in the Timing cover. The hole in the block that holds the WP shaft after you remove it.

 

I layed a nickel in the hole in the timing cover and used some RTV to hold it in place. Sounds ghetto but works really well.

 

I used a freeze plug in the hole on the timing cover. Looks clean. Forgot what size now though, took me a couple of tries to find the right one...

 

The brg hole in the block don't need any repair. Leave it just like it is after removing brg and shaft.

 

no you don't need to plug the hole in the block.
