My radiator has a very small drip at the top where the top hose connects to the engine. Could i try to put some Stop-Leak in it, or would this tear my motor up? The drip is very slight. Would putting it in the radiator hurt it or cause problems when i have to eventually replace the radiator? THANKS!

just to be different. i use the aluminum powder stop leak in everything. Works for me. All the newer cars have stopleak installed at the factory. My neighbor has a 1066 that was leaking anifreze into the oil two years ago and with nothing but a little stop leak it is still running today.

Drop the coolant level below the leak. Clean it very good and then use some JB Weld to seal it.

In the Army we even used Body Filler on the outside to plug leaks in a core for in the field fixs since raditor shops were a long way away. (worked to). I've seen surplus jeeps that still had the filler in place and had even been painted over and they were not leaking.

You should not put anything in the radiator except water and antifreeze.
All these stop leak products are just a temporary fix at best, a core clogger, usually a piston freezer and block killer at worst.
Do it right. Take it to a shop and have it repaired. Metal to metal not bubble gum to plug the hole...lol

I tried some of the stuff in my 1940 H with original radiator, it had virtually no effect at all, didn't stop the leak either!

take the radiator too a radiator shop and have them solder the leak and check to see how plugged up it is. that is the safest way and would only cost you 50 bucks.

I never use stop leak in anything ( anymore ). I always found it good in the past to totally plug up your heater core :)

I bought an old A that had stopleak put in it over the years Pat. I found it all setting in the bottom radiator hose. It had the thing plugged almost shut.
A proper fix may cost more...but will be better in the long run.
Just my 2 cents.....

Stop leak does create some contraversy, Some say that on the average pickup or auto it treats your heater like a leak and plug it right off. You hear all kinds of bad things about it. I have used it in pickups and never felt it had any serious ill effects.

I have always wondered just what I would do if it came to using it on a tractor, such as Super A with thermosyohon cooling system. I have never had to decide that one. That would be my big concren, effects on the thermosyphon system.

The other factor being, I suspect stop leak works under preasure where by presure takes it to the leak, and the effect of leak velosity is what makes stop leak work. That being the case and if your thermosyphon is the type not presurized it may do nothing, not even fix your leak. Regular black pepper will do the same job as stop leak.

I'm sure that it's been done before, but I've always been reluctant to put stop-leak in an engine that uses the thermosyphon system for cooling. It just seems to me that, without a water pump to keep the coolant moving, anything that might clog up the works can't be a good idea.

Just my opinion, others may differ.

after all the comments, i guess i will just run it till the radiator finally goes (keeping it filled up) and avoid the stop leak stuff. thanks for all the opinions!
