Default Re: Is it possible to repair the upper radiator tank without radiator removal?

Actually, removing the radiator is among the easiest things to do on a Model A.

Remove the headlights by unbuttoning the connections on the ferrules below the lamp, removing the horn wire, and then remove the entire light bar including lights and horn together without changing their "settings." Four bolts between the light bar and fender brackets.

You judge - I have removed a radiator without removing the headlights. Its possible but a toss-up to the ease of removal/pulling off hoses/extra work in the headlights.

Remove the four bolts holding the shell to the radiator. Lift shell up and off the radiator fill connection.

Remove the two (in your case perhaps three) clamps. You've already had the hoses off and things haven't "baked-in" yet so this should be easy. Remove the hoses.

(OBTW, probably all your tugging and pulling at the hoses has affected the solder joint at the hose ferrule to the upper tank. Hard NOT to do in replacing hoses with new even using a saws-all on the hoses.)

Then, undo the two bolts with springs holding the radiator base to the frame. You want to carefully make a sketch of how the parts are put together (or refer to the Service Bulletins for a pix.)

The radiator at this point should be a "walk-away" to the work-bench/repairer.

You can resolder this yourself if you can test with soap bubbles and find the leak with a modest supply of air. Don't pressurize over 3 to 5 psi.

Otherwise I would have the radiator brought to a shop and you decide the degree of "reconditioning" you need to do. Any Model A NEEDS an optimal radiator as the original design is a little "short" (IMHO) Best would be BEST, if you can afford the full boil out, rodding, thermal paint, whatever.

With the radiator OUT is the time to do these things, of course.

Re-doing work to get to deferred work is such a downer.
