What?? are you the guy with the blown head or what? Im with sound guy this post is all over the board now. I guess your the OP as you have 8n listed in the side?
But NO replacing a water pump will not fix bubbles in the Rad. Now if this is not what your asking forgive me, but this seems to be turning into a post on just about anything tractor related?
Edit: your the same guy i see! So my answer stands about the waterpump. The water pump is unrelated to a blown head.
There should not be BUBBLES of air (combusion gasses) inside your radiator, its a sealed system. Yes you can have turbulance and small air bubbles if you have a low radiator and for somereason sucked air into the water pump but you probably wont notice them unless your draining and refilling your Rad. The bubbles are from a blown head gasket and when the piston compresses it forces gasses around the bad gasket into the cooling jackets and out into the radiator where they bubble up.

the confusion is that he apparently has a case sc or similar with a water pump shaft seal going out.. leaking water and sucking air into the rad and he has merged the topics...
I was thinking that since he mentioned a water pump that there was a possibility of sucking air and causing bubbles that way. But i did miss where he said he had a leaking shaft on the water pump, which is why i said what i did.
Yea this is getting confusing. Best if we are to keep talking about this to start a new thread.
i am in need of a new radiator cap for my 50 ford 8n the one i have now does not have a spring in it like the new one do and it only has one hole in it is it ok to use the new radiator cap with 2 holes and spring?
them caps at TSC ARE Junk and flimsy! anyhow the governor on my 8n is leaking oil should i just replace the seal in it or replace the hole the governor or get a repair kit and do the seal its dripping from the bottom dont no exactly were
