Okay...I will admit that I'm not the most mechanically inclined person. Took my 93 YJ Wrangler to an auto shop just for diagnostic tests. They reported back to me that my radiator is leaking near the top seams and I need to have it changed out right away or I stand a chance of having my jeep overheat. Well....In the past, I have driven the jeep in traffic (going about 10 mph) while the weather was hot. My jeep never overheated. I told the auto ship I would get back to them. I immediately went home and popped the hood. I saw no leakage anywhere. My garage floor doesn't have one spot of any type of automotive fluid on the floor. Well...I thinking about changing the radiator myself. I have a jeep buddy who says he can help. Want to hear some of your opinions.

Get a second opinion and have the radiator pressure tested.

I had a 98 TJ that leaked along the top seams. It only did it once it was under pressure (hot). It never left any thing on my garage floor but it just kind of seeped out slowly. I could smell it if I stopped after the engine was very hot. I don't think its an Emergency IF yours is doing that. I'm sure the seal gets worse but mine didn't just blow up or anything...

You need a test rig, fill the radiator replace the cap with the testing cap, then pump the radiator up to about 18 pounds and look for the leak.
If you drove it home the water level could have dropped below the seam. You might not see anything on you floor because level is to low and or the system is no longer holding pressure like it should. Kinda like driving with the radiator cap loose.
Either way I would want to know before I hit the trails with it. Nothing like running hot in the middle of nowhere,

It's a non-repairable rad, so if it's leaking at the crimp seam it's not going to heal itself. Easy to see; you will be able to see faint yellow/green stains all around the crimp seam on the top tank. If you see the yellow/green residue, it's leaking (might not be much, but it shouldn't be there AT ALL). It won't heal itself, nor will a rad shop even try to fix it.
