new bottom radiator hose leaking

[38bill]

I believe alcohol should be the solvent for shellac.

I have used Indian Head Shellac since I was 15 years old. I
think the trick is to paint the inside of the hose and the pump
and radiator fittings and let it setup until it gets real sticky.
This way the hose don't wipe the Indian head off the fitting
as it pushed on. To remove old hoses that were put on with
Indian Head heat with an electric heat gun. The heat softens
the old Indian Head cement. G.M.

All good thoughts...particularly about the alcohol(in Me). I slopped the Indian head shellac on both end of the metal that was showing past the hose. Rotated/slid the hose in two directions. Stuff was still wet and I bet as you say, I wiped it off in the process. Anyway it still leaks. I tried some gas on the goo and it cut right thru the shellac. Contact cleaner did not. Maybe carb cleaner will. I agree that I need to redo the whole thing. I have extra hose and will heat it well so I can bend it in the middle and slip it on the pipes. I'll let the goo on the pipes stiffen first.
I will win this fight...

bad hose is off and fittings cleaned. Next step is cut the new hose to the right length, heat it and assemble

hose clamps you get what you pay for if you buy a 50 cent clamp then thats what you get you pay for premium clamps and you get premium performance best ones ive come across here are only avalible thru Mercedies benz [ genuine item trademarked] They cost but work and are close to unbreakable

I have had some leaks before at that area and it ended up being the black water pump gaskets that came with the pumps. It wicks thru the gasket and I thought was the hose leaking.

I cut the new hose a bit long and soaked it in hot water. I squooze it into position but the hose was too long and collapse and stiffened. I tried wet wash clothes microwaved but to no avail. I will have to cut the new hose out.
Getting new hose tomorrow.

Not totally sure what part of the hose you heated up in the hot water, but I would defiantly only heat the end that goes over the fitting. The term soaked is also interesting, you should only have to place say 2 inches of the end of the hose in some hot water for a few seconds (maybe 5 to 10 seconds). This has always worked for me. If the whole hose is "soaked" in hot water I would think it would become very difficult to work with. Also, you need to be a bit gentle on the radiator end, the water pump end you can manhandle a bit.

I had a leak on a 226 hose that I kept chasing. It ended up being a hairline crack in the outlet. Not saying that is what you have, just the possibility.

get a good clamp.. if you you use indian shellac on the rad hoses & a few mounts you need to replace a water pump or fix a rad leak you will find out why they call it shellac because you will be getting a shellacing taking the hose off.why should a sealer be needed on a soft hose get a good clamp. every day in our shop will deal with all this sealer crap mech. use on gaskets that don,t need sealers. especaly that rtv stuff

Wow so much angst over a hose. I have only used #2 Permatex on gaskets and hoses for over fifty years and it never failed. JMHO

[tubman]

I'm with "3twinridges". I think there may be something else going on here.

[Clem Clement]

new hose home. Nappy time

[Zeke3]

Nap time! Clem, don't leave us hanging, did it fix the leak?

[Clem Clement]

it will, I hope. This is a piece-meal project hopefully nearing completion.

[Clem Clement]

Nope: Failed
I heated the hose and slathered both ends at pipe with shellac. I got the pump end on and fully in. I could not get the other end over the radiator pipe. I tried all the tricks I know. Then it was dinner time and Momma was upset with me as the thermal status of her mighty fine dinner (I left the open end open as I worry about forcing the hose over the rad.end and breaking the solder loose.) Today I tried to remove the hose to no avail. I have 2 horns nearby that get in the way.

My plan is to cut the new hose off and use gas to remove the shellac. Then rest this project. I don't know why the shorter hose with plenty of shellac still leaked. Thanks for all the good advice.

I might remove the rad. and start all over with the assembling process.

What is the difference between Hylomar AF and Hylomar Blue? Does one work better on water hoses than the other?

[Clem Clement]

Tomorrow I heat the hose with wet towels from the microwave. Tap hot water not enough heat

[tubman]

Clem, I gotta say it again. There must be something else wrong. Clean everything up and take a closer look. I have put some hoses on some pretty crappy radiator spigots and NEVER had this kind of trouble.

Okay "Kube"(and others)



I shellacked "ALL" my hoses, rads, heater hoses and all BUT the two at the head are nice and sealed. The two on the head are "STILL" leaking. I applied the Indian Head on both the hose and outlet and waited at least an hour before I installed them. NOT sure if it is "temperature" sensitive but it was about 58 to 60 and it was "tacky" when I installed the hose. Then it sat for at least 24 hours before I added any coolant. SO, I went ahead and cranked the car to see IF maybe getting it warm "might" help with the sealing process and as it got warm it started 'Leaking worse" and the more I tightened the clamp the worse it seemed to get. Did I do something wrong??? I read the directions on the bottle and don't see anything I missed.
