Got the top of the radiator all free to remove, but now I am at the bottom. It seems that one of the nuts on the bottom have cross threaded and I am at my wits end. I have almost got it, but the edges of the nut are almost gone and I am afraid I am going to be in big trouble!

Question.....Are these nuts accessible if you remove the frame rails. I can't tell by feeling in there, but thought it was a possibility.

Thanks for any input.

Excellent advise Ray! It might allready be too late, but Doug, I'd use a lot of patience and plenty penetrating oil and let it soak a day or two. Those radiators are not made to hammer and saw on, unless a last resort and then it becomes an expensive project. Be tender and say a pray. You just might be surprised!

Doug, Removing the frame rails will not help you. If the 6pt socket doesn't do the trick as Haas suggested, try using a universal with the socket. Last resort is the hacksaw option and replace the stud before reinstalling the radiator. Did you have to remove the cotter key in the castellated nut that is stuck?//FB

The cotter key is the problem. I know I did not get all the pieces out and went ahead and started the nut off.

Thanks for the advice, all I have are 12 point sockets, so I am going to find a 6 point for this somewhere.

Doug:

Just a thought,.... how about running a new nut up on the stud careful like and it just might shear off that cotter pin in the thread recess letting the top nut unscrew down all the way?

Thanks undertaker, that is what I had in mind, only running the top nut down over ther cotter pin since the pin looked to be really rotten.

Well is was just good enough to get the threads screwed up. The nut on the other side would not budge. I ended up cutting them with a chisel. I have plenty of bare knuckles to prove it.

Don't know about the H, but on the M, you can get a socket with an extension on the radiator bottom bolts. Don't know about the frame rail question. However, suggest you get a 6 point socket if you have been using a 12 point. Sometimes the 6 point will hold where the 12 won't. Also, I would think you could use a hacksaw and saw the bolt off where the radiator rests on the bolster. It is a stud bolt on the M. May be hard to get it out. On my MD, one of the bolts was welded or soldered in.

I wouldn't saw the bolts off. Made that mistake. Mine didn't have nuts, just the studs. The studs were in bad shape and I cut them off. Then there was nothing to keep the bottom part of the radiator from shifting around. Had studs welded back on. You don't really need the nuts just the studs, and a piece of inner tube padding between the bolster and the bottom of the radiator.
I think the trainees designed the radiator while Raymond D. (forgot his name) was taking his coffee break.

I was assuming that the studs could be replaced. They are just stud bolts threaded into the bottom of the radiator. Getting them to unscrew out of the radiator could be a problem though.

They are studs. But judging from the many posts on this subject it appears all have been frozen in or welded over. Mine was already worked on by many and the studs were welded in some time along the way. That bottom part is a weak piece of copper and susceptible to shearing around the stud socket.

Doug D...they are studs!

I got that radiator out by cutting the nuts off with a chisel. They are studs that came right out of the radiator with vise grips and muscle.

Looking back on the comments, There was no way I could get a socket on those nuts. There was barely room to get an open end wrench in there to get a hold of them. This is a 1940, maybe some of the later ones were designed with enough room for a socket after enough mechanics griped about it.

Somewhere along the line them Farmall engineers got wise and had holes casted underneath the studs in the bolster. My 1945 and 46 Hs are like the 1940 which requires a box or open end wrench and a lot of cursing. The 1951 I rebuilt two years ago had the casting holes. It sure made life easier!

Glad to hear you got it fixed! I'm going to look at my M again, but I recall using a socket to get the radiator bolts off. Maybe the H is different, or I just forgot. I do remember it was not easy and getting them back on is not easy either!
