Off Topic Leaking oil cooler.

[Way She Goes]

Has anybody ever tried to soldering a small leak in the cap of a power steering oil cooler. Right on the back of the engine, had to take the back of the boat inside compartment off to get at in my 87 thundercraft Magnum 190. Got it off was going to try it. But have to wait till the stores open to get some gas for the torch.
Good thing I put the ears on before dragging it to the lake.

If I could offer one piece of advice, make sure it is as clean as you can possibly get it. It will help the bond of the solder.

Had the same issue on what looks like the exact same cooler a few years back.

is it off an OMC?

I sanded and cleaned it up real good , hit it with lots of solder paste, soldered it up and never had a problem.

i was lucky the next year and picked up a used cooler , so have the soldered one for a spare.

I try and make sure I get antifreeze in all of the lines from the stat housing when i winterize now. The line my cooler is on dumps antifreeze on the ground , but replaces the bit of water that stays in the cooler, preventing it from splitting again hopefully...

What about JB Weld? Would that work for what you’re trying to achieve?

It is an OMC. I am going to solder to try it, and pressure test. Thanks @doubletime . I always use antifreeze but must not have put enough in this year.

call Gary Laur in Aylmer He owns the Aylmer Rad shop. he will be able to give you anything you need or do it himself. I worked there 25 years ago. He is a good guy

I like JB Weld as my soldering skills suck . LoL ! If you go HOT keep a fire extinguisher nearby or cover parts with wet rags ... just in case ?

Duh ! Just looked at the photos close up , thought you were working inside the boat. However you attempt to fix it ......... safety first !

Thanks got it solder up and ready to put back on boat. Did a pressure test for 30 minutes no leaks. .

Hope no solder entered the oil side. But the pic looks like just the water jacket.
