Radiator leak question

Postby Brent » Fri Nov 12, 2004 10:07 am

:? Has anyone used one of the aluminum based radiator sealants? I have a small leak and that's what the auto parts guy suggested. Seams to me that the Cub's or any other cooling system would be ripe for electrolysis if you used anything with an aluminum base.

I'm not confident that any sort of radiator sealant would work on a non pressurized system. You might be better off with an external repair or replacement in the long run. Just my 2 pennies worth.

If I was going to use anything in there it would be waterglass. (sodium silicate) I have seen it used effectively for many years on old tractors although I don't usually recommend using such things other than on a temporary basis.
Be prepared to work the tractor to get it good and hot and to keep the water circulated for a while so it will distribute.

If you can't fix it with a hammer, you've got an electrical problem.

Around $130.00 for a new radiator. I pulled my leaking radiator and soldered the leak. Reinstalled the radiator only to find that it had developed leak in another location.

:censored: Thanks Gents, I forgot it isn't a pressurized system. The radiator was new about a year ago so I think I'll take it out and fix it right. It's only a pin hole leak so it should be fixable.

Get you a board and notch it out for the flues and bolt it down with a gasket and wood screws so the radiator shop can leak test it. He want have anything to do that and may turn you away unless you have it already made and bolted on. Rudi is the wood craftsman. Have you made one Rudi.
