Patch small radiator leak?
 

HI, my 2002 S60 T5 with 115,000 miles has a tiny leak in the radiator. I had to change the old radiator in October because of a large leak. A new one (not Volvo) was installed then, and now we find a tiny leak. I noticed the leak when a few leaks ago, I received the message "engine coolant low". I poured water in the coolant compartment and 2 weeks later, all the water was gone. The mechanic identified the tiny cracks.

It was suggested that we fix the leak with industrial epoxy. Good idea or not? At first i thought it was fine because at 115,000, I don't know how long the car will last. But now, I am not sure if it is the right thing to do.

Thanks
