Leaking Radiator Core

Try a product called "Stop Leak".

that will gum up his cooling system and possibly cause overheating issues.......It wouldn't b my choice

I doubt it.

OP, ALUMASEAL Radiator Sealer Powder, .70 oz - Additives - 2AEP8 ..

I've used this with great results. And it is cheap.

my comment was not on the Alumaseal product I was referring to Stopleak http://www.youtube.com/watch?v=76GpMD4LIwY

OK.

Don't know about "stop leak".

Do know Alumisxxx works.

Don't know why I typed Stop Leak when I was thinking about Alumaseal! Doh!

I have used stop leak with success as well as the aluminum product. I was told by a salesman that stop leak was made from black pepper and his claim was that black pepper worked just as well. I tried it at least twice and it stopped the leaks. I have disassembled engines that had sealants used in them with no sign of gumming or buildup. Actually the water jackets were quite clean and all coolant holes in head gaskets were free from buildup. These products only congeal when they are exposed to the leak source. Warm the engine first, install the sealant and replace cap give it a try, oh yes read the instructions there may be some variation.

I got home across 250 miles of the Mojave desert with home made stop leak made by shaving half a bar of soap and half a can of black pepper. Worked good enough to get me home and around town until the next weekend when I had time to fix properly. -- JHF

I've used just pepper, and ran them for a couple of years without ever doing anything else.

I suppose it depends some on how bad the leak is. Mine was pretty bad and hard to get at. My first try was to pinch off the 2 tubes that were pierced. (By me while replacing the water pump. What a 'vacation') Like I say, hard to get at, so the soap and pepper trick. It actually lasted several weeks and was re done a couple of times before Mrs. Circuit Breaker started make threats if she had to add more before she could go to the store! -- JHF

I'd get it re-cored or replaced....

Cut out enough to reach the hole and solder the individual cores. The radiator won't notice the difference. You will only lose a few coolant cores.

I've done it. It works.

Thanx for the ideas guys...but what about my first option which is to push an epoxy into the gap?would it work good?

Make sure it's clean and dry.

What are you waiting for? It won't make it worse.

Jeez... If I get on here and ask everyone how to fix my profusely bleeding leg, I'll be dead by the time I get a decent answer.

"..............how to fix my profusely bleeding leg,"

Just pour some epoxy over it.

Don"think that will work very well, I have used cyanacrillic adhesive for the bleeding leg sysdrome, works well and is as good as stiches. 'superglue' should be in every first aid kit and toolbox. (personal opinion)

If you decided that the online forums were a better place to go than the emergency room then yes you rather deserve to bleed to death.

You're only making life better for the rest of us with a decision like that plus you give me a bit of entertainment before you go.

Inhaled chlorine gas from pool chemicals

Wow!!!

How did I miss that one?

Your posts were funny, but I liked yamdanky's the best.... told the dummy to come back and let us know they were okay, and promptly closed the thread.

If only I had the power..........................

Your talking non sense dude on this...

You are new here. It's forgivable.

(Unless of course you are really just someone elses second or third identity here.)

As far as your radiator goes if that leak is not from physical damage the inner part of the core is rotted out and you are in for a lot more leaks forming in the near future so start shopping around for a good rebuild place or a new radiator because you will be needing it sooner that you think.

just tie it off above the point of bleeding. Then get help as fast as possible.

============

For the radiator if you can get to the leaking tube. You could cut, crimp, then fold the ends and crimp again. It should not make much if any difference in operations.

Or if you can get to the end of the leaking tube from the tank ends you can plug the leaking tube from both ends. Same different.

Putting the epoxy on the outside may not last. depends on expansion contraction and operation pressur of the tube/Finns around where the epoxy is placed.

Im not saying an epoxy wont work I just wouldnt do it for more than temp patch until I could make a permant mechanical seal with solder

I've used epoxy on a car radiator after the fan came loose & cut a swathe through the fins. I simply poured the epoxy over the fins, no finesse at all. It was quite a large patch but the car ran OK for several years.

Working on old cars and trucks, it's been my experience that a leaking head gasket really needs to be replaced along with checking the flatness of the head - maybe leading to regrinding the mating surfaces. For radiator leaks, depending on how bad rhe radiator is damaged, epoxy can be a permanent repair. Just remember, if the radiator core is leaking due to old age rather than some form of trauma, it's likely to find another weak spot to leak thru. BTW; if you need a temporary stop leak, I recommend a product known as 'Bar's Leaks' it works better than other products for me.
