Radiator question

What is the difference between a 1 row and 2 row radiator? Mine is leaking so it needs to be replaced. Should I get an all aluminum, or is the one with plastic tanks ok? I have seen plastic tank ones online for $80, but for $40 more I can have all alum., just wondering if it's worth it.

The experts can correct me if Im wrong but the 1 row cools better. Also definatly go with the aluminum radiator. they last longer. But if your jeep doesnt see the trails then you should be fine with the plastic.

Increased heat transfer and effeciency is gained by the larger cooling area. Plastic radiators by design are a short life cycle part meant to drive replacement parts sales.

a 1 row radiator has 1 row of tubes.
a 2 row radiator has 2 rows of tubes.

generally, there is only so much width to shove tubes, so as the number of rows goes up, the width of the tubes goes down.

None of the radiators we use are plastic, the actual cores are aluminum, brass, etc. though they may have plastic tops and bottoms. The OE radiator has an all aluminum 1 row core which is an upgrade/better cooler to the original 2-row all aluminum core. An all aluminum core is hard to beat.

The inexpensive all-aluminum radiators are generally going to be constructed so shoddily that they require an expoxy liner to prevent them from leaking... which reduces how much coolant they can hold. Good quality all-aluminum radiators are going to be very expensive and other than their added bling, don't usually cool any better than the OE all-aluminum core radiator.

Early TJ radiators, from '97 to late '99, were prone to leak within their first 20-35,000 miles. My '97 had multiple radiators until they got that issue sorted out and taken care of late 1999. Personally, in view of the cheap radiators so many online sellers are passing off as good quality, I'd stick with an OE replacement. Most of the online cheap radiators come from China and their quality is all over the place.

For one that has tried the stock, aluminum, and now the copper & brass rads, stock fan, elect and etc, the one that works hands down better is the 2 row all metal copper brass direct design and replacement. I also replaced the fan with a 10 blade 18" and a HD fan clutch. The jeep stays rock sold cool under all circumstances. I purchased mine from the radiator barn $340 shipped to your door and brand new.

I wouldn't call 14 years a short life cycle, which is how long my original factory radiator with plastic TANKS lasted.

What's funny about this is my bone stock set-up does the same thing, I never have seen the temp more than a needles width to the right of the 1 in 210. 2 years in the desert, 110-112* rockcrawling with the AC on*(Cause my lady is fancy that way) pulling a long hard grade at 3000 rpm in 3rd nets about 215* which drops as soon as I crest the hill. One bottle of Water-wetter is all I have over stock.

Thanks for all the input, now at least I can make a semi educated decision.

My OEM radiator is 10 years old. The day it springs a leak, I'll head to the dealer for a replacement. I've used aftermarket radiators, but only for engine swaps, and then only the best made in USA stuff.

That water wetter stuff has proven itself in motorcycles, but make certain whatever brand you use is fully compatable with your coolant.

As DevilDogDoc said, mine does the same thing in screaming hot desert wheeling conditions and it is 100% stock. Stock radiator, stock fan, stock 195 degree thermostat, stock everything. When properly maintained, the TJ's STOCK cooling system is more than up to the task. And I doubt you wheel in conditions as hot as the conditions we see regularly in our SOCAL deserts.
