Cub Radiator

Zach Bouchard · Nov 18, 2009

I need to take the radiator off of my cub but i"m a little worried about sealingit back up when i put it back on. It doesn"t leak now but i am restoring my cub and need to take it off to strip and repaint the front of the engine. Is it that big of a deal to get it to seal up or am I worrying for nothing?

Unless you have reason to think the radiator is somehow especially tender, I suspect you're worrying a little much.

The bolts that support it don't put any real tension of the core or tanks. That leaves the hoses, and as long as the radiator isn't fragile to the point of failure, it shouldn't be a problem slipping the hoses back on and clamping them.

The cub radiator is a little different since the lower bolster is part of the cooling system. There is a gasket between the tank and the bolster. As long as the mating surfaces are clean and smooth a thin coat of RTV on a new gasket should seal the radiator without a problem.

I'm livin' and learnin' every day.

Now off to the parts pages to look this rig over.

Thanks, BD!

Glad to hear you are boning up on your Cubs! Could come in useful in a little bit here.....

Be careful removing them 5/16" bolts, they are pron to snap off, why remove rad. you can remove casting & rad in one unit from engine if need be.

I removed the steering sector with the rad still fastened on that way you can get a better paint finish on the whole assy.
