swapping water pump

[martinlaw]

Can anyone help - what is the third hole below the mounting bolts on one side for?

I am swapping the water pump from one engine to another. On one engine the third hole below the two mounting bolts is blocked off by the gasket and on the other it is open.

Should this hole be open or closed off? What is it for?

Cheers,
Martin.

Hi Martin

Don't worry about it! Some gaskets come open some closed. It just a throw back in the casting no longer used. I always use a thread sealer like loctite 572 on the bolts threads as some of the bolts enter the block water jacket.

Thanks Dave,

I am swopping all the bits from my old engine onto the one I have bought off Kyle.

This is all new to me so I hope you don't mind me asking more basic questions?
