Radiator/Cooling System

[timejati]

So if I have a non pressurized radiator where can I get a cap for that? I was going to order one of the wing fancy style but they all say for pressurized system. The other style says for 4 psi systems. Also, what will happen if it would be a pressurized system but the cap on it was broken and no spring or seal in it. Not sure if that was intenional or not. - Thoughts?

What do you have that doesn't have a pressurized cooling system? Most of these old tractors have preesurized cooling systems to raise the boiling point of the coolant for effective heat transfer under hot ambient conditions.

Ford 9N. If I understood right either 1/2 or most of the 9N's were non pressurized. Since I doe not have a S/N I don't know the year. The Rad does have a long neck with a ledge about 2 1/2 or so inches from the top of the rad.

Timejati.......would it surprize you to learn that there are BOTH unpressurized and pressurized "winged" radiator caps (you doubt? check it out) and they are NOT interchangeable??? The sealing lugs are different.

Most old 9N no pressure coffin-tank radiators have been replaced with more efficient 4-psi radiators. .....Dell

Check with nnalert. That's where I got my winged cap for my non-pressurized rad..Nothing wrong with the non-pressurized..Been working for 60+ years on mine....I guess that means they aren't much good...

Ya know Dell, Nuttin surprises me anymore. I may try to post a pic of the neck of my rad. Would that help to determine for sure before I f*^%# things up?

So, when looking at your radiator what is the physical appearance to determine non pressurized vs. pressurized??

The chances of you having an N w/ a non-pressurized radiator are slim because the pressurized radiators came out in early 1943. But, in the event that you do have one or, the even more unlikely event that your later model N has been retrofitted w/ an old radiator, look at how the cap fits into the neck. If the lugs are on the outside of the neck, it's pressurized. If the lugs are inside of the neck, it's non-pressurized. At least that's what I remember!

All three of mine have lugs out, so pressurized. Never seen a lug in unit. Thanks for the info. Bruce{AZ}.

I have a 52 8N and my cap looks like the 2N one in your picture whould that mean that I have a non pressure system?

I think the 9N one is the no pressure.

My 49 8N has the same as the 2N one there.

So, in summary, this all boils down to an inny or outtie? :lol:

Drew.......understand this, yer 4-speed 8N came from the factory with 4-psi pressurized radiator. The coffin-tank no-pressure radiator was NOT even available for replacement in 1952. The 2N-cap pictured is a pressurized cap. The shadows makes it hard to see the radiator neck lugs. They are DIFFERENT from the very visible lugs on 9N NO PRESSURE cap. .....respectfully, Dell

 

[Dell (WA)]

timejati........look at the pictures. See the lugs on the NO-PRESSURE 9N cap??? Iff'n you don't have the coffin-tank radiator, you ain't gotta no-pressure radiator. Dunno how to 'splain' more better .......respectfully, Dell

Here is a pick with (if I ain't a complete pud) the lugs on the outside. So non pressurized huh. The cap obviously not original. Fact it is a 13 psi that is broke or modified? Who knows.

It looks to me to be a cap (wrong cap) that has seen it's better days, and offers your radiator NO pressure.

But I could be wrong....

Does this shed light?

That's what timejati a.k.a Pud... like... Pictures to put with dem big words like lugs. Thanks guys. In closing it must be the pressurized system 4 ish' PSI and it ain't look nuttin like tat "coffin" one. And yes my cap is a 13 psi, and was broken. Remember I am the very definition of shade under the grass under the shade tree mechanic. I outta start all my subject lines with DUH! FYI, I think my wife hates everyone on this site. Apparently I talk more to all you then her.

You are welcome! Remember, I didn't use 'big words' before...I said, 'it all boils down to inny & outtie'. :lol:
