Well i had 173,000mi on the original radiator in my 98 TJ before I started noticing i had a slight leak on the bottom area between the fins and tank. Previous owner was using just plain water in the radiator - so the inside was pretty well rotted- (distilled water is always better in the mix). Decided to replace it with an all aluminum radiator- runs much cooler now! Best decision in my opinion- going aluminum!

Since I didn't (and still don't) have the money to replace the radiator yet, I tried it. Hasn't leaked since, temp guage still shows the same temp, heater still works fine.

99 Sport w/105,000 mi and original radiator.

Yeah, it's a neat trick that. I heard a similar trick and used dried/powdered ginger for a leak. Put a pinch in when cold then run up to temp. It migrates to the leak and swells up in there. It doesn't crud things up like Radweld does.

cant help ya with your questions DrDonahue, and since they were from january i'm assuming you may have solved the problem anyway. I havent fixed mine yet either, i had a different thread where i asked a few questions about it. mostly answered my questions. although my rad leaks, it doesnt overheat. I just am between a rock and a hard places because i dont want to spend the money to begin with, and if i AM going to fix it, i'd rather throw an all metal beast in there that will cost me 300$. and that money isnt just laying around lately.
also cheers to a 7 year old thread. still not as old as my radiator though ..12 years 120000 miles and it just leaks a little.

I've got 130k miles on my TJ's factory radiator. Recently flushed it. Going strong!

Thus a recorse is to replace the OEM plastic one an inexpensive site I was directed to (raditorbarn.com) sales 2 and 3 core rads about 130 and 160 I think and shipping is included. Not a bad price considering some Ive seen at 2-3 hundred others gave good review of the place I have not yet bought one trying to get evry mile out of the old ones.
I've got a 2000 TJ and mine doesn't have a plastic top or bottom.

Yes it does, all Wrangler TJs do. Maybe yours is an aftermarket replacement.

Not being picky, but I probably need to replace my radiator and I'd love to hear about steps and pictures of a radiator actually being replaced. If anybody reads this before the summer, post some pictures!

Have read several threads concerning the choice of 1, 2, or 3 row cores on the replacement radiators. I'd like to replace my original 2001 leaking 1 row core radiator with an all aluminum one to get away from the plastic tanks but most of them are either 2 or 3 row cores and have been trying to decide about the choice of either 2 or 3 row. Maybe it won't make any difference. Even though my current leaking one has never heated above the center mark on the gauge I want to make sure I don't change that with the wrong radiator.

What is the difference between different number of row cores?

I've read some thoughts that the original factory one-row core has larger tubes and is supposed to cool better than 2/3 row cores with smaller tubes (I think the core can only be just so wide in order to fit any particular vehicle).

So those are thoughts that you have heard. In general is it supposed to be that more core rows is a better cooling or vice versa?

That's what I'd like to know before I order a new radiator.

Had my jeep since new. Owned a factory obviously. It leaked slowly almost it's whole life. Had a Griffen. Was a pos lasted less than 6 months. Had a drake it was just as big a pos. got a Napa now and it has impressed and was cheap. Aluminum core. Plastic tanks. I don't recommend stuff often but this radiator was flawless when I lived in Alaska so it's the king to me.
