Finding small radiator leak

Postby Xperimental » Thu Jun 28, 2018 12:07 pm

I noticed after mowing an acre or two of fairly rough ground with a C22 sickle mower, that my 62 had some coolant around the crank hole in the bolster. I removed the grill and found coolant seeping from somewhere behind the left hand radiator support at the very bottom of the radiator. I put a bucket under it overnight and found it lost a few ounces of coolant in 24 hours. I examined the area in every way I could but could not see the source of the leak.
I removed the radiator yesterday and can't see any suspicious places where it is likely leaking. I am wondering if the problem was the seal between the radiator and bolster, but that is less than logical, since the coolant seepage was visible on the top of the radiator flange. The seal, on the left side,did not seem very secure when I removed the 18 bolts. It has been sealed down with some blue silicon and the silicon had let go on the left side. My problem is that I don't want to replace a good original radiator, yet I do not want to put it back together only to find out it is still leaking. I doubt that any local radiator shop can test it because of the open bottom design. Is there any good way to seal the bottom of these radiators temporarily so that leaks can be found? I am considering rigging up some sort of plastic around the bottom and filling it with water.

Most old time radiator shops have a method of sealing the bottom. I have clamped a board lined with rubber that worked just fine. Most shops use very small psi for testing. So, it can and is being done.

Leaking on the bottom of the radiator at the front tube.


I used an idea that I found here and sprayed soapy water into a few likely tubes from the bottom of the radiator. When I blew a little compressed air into the tubes, I quickly found out that at least three are leaking where they join the bottom plate.

Probably be ahead to get a new Clancy radiator.

Hi,
If the radiator tubes are corroded through, and can't be fixed, the guys on here have said that the radiator TM Tractor sells is a good quality and fits good. I have never bought one there.
They have said some online don't fit well.
There is supposed to be a gasket at the bottom of the radiator. You can see it in the listing. :)

You might need a new upper radiator hose, if it hasn't been replaced in years.

The three tubes that are leaking are not corroded through. The original solder joint on each of them has loosened. It looks like the joints could be re-soldered, but I am debating with myself. As many of you know removing and installing Cub radiators is a bit labor intensive. I have read and heard that the Clancy radiator is a good choice, if replacement is necessary.

I've had a couple radiators tested and reconditioned/repaired within the last year. Local shop charges about $75 for the work.
