I'm with "Floyd" on worm-drive hose clamps.

I'm using some original clamps repainted. I'll study them for defects. The hose is loose so I may have stretched the hose with WD40

I aughta explain. I haunted junk years as a young men. I was a Major in the Air Force before I actually bought a fuse/light bulbs, most screws/bolts/etc. I learned a lot about what goes where. So when the '39 peecup invitee hisself into my life, I promised to do good work at a minimum cost. Thus I have a box of hose clamps, a sack of rubber bumpers. All in good fun!

Are the hoses you're using Red Stripe Vintique's?

Yellow stripe.

It is a straight shot from the bottom of the rad to the water pump. I need to bend/squeeze the hose to get it on.

I'm using uses A12 clamps. I see no reason for the leakage. The hose seems a little loose, so maybe it is wrinkling under the clamp. Could the WD 40 have caused the hose to swell between installing time and tightening time? I'd like to know what I did wrong before I proceed.

Clem, I doubt the WD40 caused any issues. You didn't soak the hoses in it - did you?
I tend to boil the hose to make it more pliable and get it in place before it cools off. Also, I'll say it again... INDIAN HEAD SHELLAC. Trust me on this Clem.

Not sure that is the issue. Never hurts either. It stays semi liquid for removable.

Always should have some indian head shellac on the shelf while it's available. It is really the first peramtex. It is fuel resistant also.

Do you use it on ALL the hose ends on your cars or JUST one that doesn't seem to want seal??? I have the uppers off the Merc as we speak and have one lower (radiator side) that just doesn't want to stop dripping so stopping today for a bottle.

I use it as a matter of course on all hoses. Removing a hose later is easy.
Especially with fresh restorations, I dread the thought of anything leaking.

YAHOO. Thanks all. Great friends of Fordbarn!!

Let me tell the rest of the story: A few years back a couple of clubbers got a call that a free '38 dump truck needed to be stripped of goodies and removed. They got the dash and lots of parts(No fun as the truck was buried in the sticker-bushes.) I was asked what I was asked and the answer was the big generator and the fan should. Yes the Model A started with shrouds and apparently the working flatheads has one as well. I got cleaned up, straightened and painted and waited for another day. My middle son visited during my heart procedure last fall and offered to fix something. Weeehoooo. Turns out the repo radiator was previously installed leaning backward Guesses were that longer upper hoses were too short or the top brace rods were too short. Anyway lots of air went around the radiator, not thru. I could not do any work to the happiness of son Joe and he moved the rad to near vertical. Rad duct tape finished it off. We also had to replace the hoses as the hose fitting area for the heater was bad.
Oh, did I mention that I had two uuuugly horns under the front end. One had been on my 41 Ford coupe as a youngster. That sucker is loud and more than once it fooled a big trucker thinking I was a big truck. Thus there is relays, horn wire etc. near the bottom on driver's side.

I slopped the Indianhead shellac on the radiator open ends and tried to set the clamps. The original problem showed itself. The clamp bolt was the longest I could find. it caught in the clamp allowing the nut to be outside the holding tab. Thus the nut would spin and not tighten (it did bind in the threads rubbing the clamp edge.

Fixing that and things tightened up. Water in probably tomorrow.

Tears...Water leak. Resealed it. I may have to clean that mess about and use a hose boiled in water first….

Clem, I'm not being a wise guy but did you follow the directions on the bottle? They are important with this stuff.
Coat both the radiator outlet and hose inlet. Let it get quite tacky before assembling. If the radiator outlet is round, there's no reason you should have a leak after doing as instructed.

I tried. I slid the hose back and forth and rotated it several times. Does gas cut the shellac? does that make sense? If I remove the hose I would need to cut it off. If I pull hard I don't know if the radiator can stand the yanking pressure.
I have added a galloon water and no leak so far. It has a low pressure cap for the rad

I don't think so. However, a new coating should soften what's already been applied.
