Angry Radiator is leaking... Need new one. 98 TJ 4.0

Pretty sure my radiator is finally dead. Ive read a lot about how the seams fail and they are un repairable. Seems like just about everywhere on it is leaking.

98 TJ sport Jeep wrangler 4.0 Automatic.

Whats a good replacement, where to get it, and how much?

Would this be a good time to purchase a separate automatic transmission cooler too?

Thanks.

Ageless Stranger just replaced his rad last week. He can probably recommend a good place to get one. He also replaced the t-stat based on advice he received here, so you might look into that as well. Afaik, TJ's don't really need transmission coolers. JK's on the other hand seem to have an issue.... But get more advice on that, cause I honestly don't know for sure.

I bought the 2 row CSF replacement from HERE.It is $178.00 shipped to your door via FedEx. They have a shipping map on their site that tells you how long it will take to get there, and it was dead on. I ordered mine after the cutoff time for same day shipping (3:00PM, if I remember correctly) on a Wed. night and had it on Monday. It is all metal and is a direct swap for the factory radiator. I changed out my t-stat per the advice of Tim (distortedtj) because like he said, you're in there already so go ahead and do it. The t-stat and gasket was 5 dollars and change at O'Reilly auto parts. Buy the OEM t-stat, 195 degrees.

Pretty straight forward DIY job.

Also, it already has a transmission cooler built into it. The hose barbs are sticking out the bottom of the radiator.

Here are some pics of mine.

Mine rolled over to 65,000 this morning. I think it's probably as much a product of time as mileage. Maybe not, but mine is a 2000 model.

I am interested if most people get a single core or a dual core radiator? Or possibly a three core.

Hmmm my 97 had the rad replaced in 06 but I don't know how many miles were on it when it was changed out. I have an oem replacement in there and it cools perfectly. There have been many threads about this and a friend of mine has put countless aftermarket rads in many rigs and at this point has not found anything that cools better than factory one pass rads. If and when mine craps out I'll put another in just like it.

I wasn't trying to achieve better cooling, I've never had a problem with overheating. I was trying to get away from the plastic crimped on tanks. All metal is the way to go, IMHO.

Interesting. The stock radiator was a single core in my old XJ (4.0) and if you got the towing package it came with a 2 core. I bored it out and the 2 core could not keep it cool enough. It was only when I had a 3 core radiator put in that it kept the temperature at 210. All of those were all metal radiators.

The first TJs came with a 2 row and after some cooling issues DC changed it to a 1 row and that's what has been put in since. Cherokees had their own cooling issues at least the early ones with that funky system that they had. At least here in the desert in the rocks my one pass has been flawless in 110 temps with the AC blasting. I never get past the 1 in 210.

I pull a small trailer a lot and lately it has seem to be getting way to hot. So whats better a single core or multi core?

Seems like i can buy a 3 row or 2 row from about the same price (from radiator bard). I haul that trailer a lot so what would be best?

The 2 "row" will probably be the best option. I think that all the radiators on RB's website are single "core" and have 1 or 2 rows inside that single core. I would have to read the whole thread distortedtj linked above to say for sure. Maybe someone with more experience can chime in? Like I said, I had never had any overheaing issues before mine started leaking, and I pull a small trailer too. Maybe yours is just low on coolant?

Seems like a pretty good run on the original why not get another just like it? I mean if it cooled well and lasted that long why mess with it? And as far as radiator barn goes some folks have reported there rads leaking very shortly after being put in. Sure they will warranty it but I would prefer to drop in the new one and forget it for another 155000 miles.
