Welding the Radiator Support

Postby robertw144 » Mon May 16, 2016 2:04 pm

I have been researching this forum regarding welding the Radiator support where a crack runs along just in front of the radiator. Some are for it. Some are against it. I have a professional welder friend who is going to come take a look at it. Considering the casting technology back then and the thickness of the metal, what kind of advice can I give him. I figure it is worth a try.

You are talking about the steering bolster? hoo boy... Antifreeze cracks are not the easiest to repair.

Regular welding rod will crack or sometimes not stick to cast (Especially if contaminated with antifreeze). I've had the most success brazing cast iron- the bronze is softer and a little more elastic than the cast iron, so a weld won't reopen.

I have heard some using muggyweld (http://muggyweld.com/cast-iron-repair) fairly successfully, but you have to go fairly slowly or the iron will turn brittle.

Gouge the crack open as much as you can, and preheat the part with a propane torch. after welding/brazing, bury it in vermiculite or sand so it cools slowly.

The bolster, in front of the radiator, on my Cub had been brazed at some distant time in the past. The brazing is still holding, not leaking coolant.
I have an excuse. CRS.

I would be more concerned with the welder's ability than the crack itself. Cast can be welded successfully if the welder knows what he is doing. They are fairly easy to find out there if you look enough but hey, try welding first. Good luck!

I have several that were welded or brazed, by previous owners. All are holding antifreeze without issues. If the portion of the bolster, where the front of the radiator bolts on, is bowed up, from freezing, the radiator won't seal properly. As long as that area, is flat, it should be fixable, by an experienced welder.

Cast iron rods should be used welding but brazing is the better way to go IMO. Welding may give you small holes and once they are there it will be hard to get them to stop leaking. Brazing will get down in the crack better and the initial heat from the torch should burn all the impurities out of it.

Welding was successful. Not pretty, but no leaks!
