2 row aluminum for sure! 3 row is excessive, and not needed, I have 2 row aluminum, and it works great.

I've heard the 2 row is good but when its 110 and your sitting there in traffic with the ac on will it keep me at 210 or just below 210
my temp stays just below 210 with out the ac on but if I turn the ac on it will climb just above the 210 mark

and is the 2row metal better than the aluminum stock replacement

If you are running good speed in say a race car or dragster then a 3 row would be great.

However I don't feel that at the extremely slow speeds that we crawl at there is enough air movement thru a 3 row to make it worthy for our application. The 2 row works much better in our case.

that's not he first time I've heard that

now for about the same price I can get a 2row metal radiator or a aluminum replacement

there's like a $10 difference
same with the 3row

just get the 2 row metal. radiatorbarn.com usually has good prices, thats where I got mine from, works great. whatever you do DON'T get the replacement stock one. the damn things are made out of aluminum/plastic and afer time will leak just like the one you have in the jeep now.

my radiator doesn't leak in fact there's nothing wrong with it it just doesn't cool efficiently enough when I run the ac
If I don't turn on the ac my temp stays below the 210 mark all day but if I turn the ac on the temp is just a hair above 210 unless I'm sitting at light or wheeling, in a drive through then it gets about mid way between the 210 and the line before the red

so all I need is better cooling when I run the ac

it looks like the 2row and the 3row radiators have the same core dimensions so I think the 2row is the way to go

Actually I believe our stock radiator is like every other stock radiator.. Its made out of brass and welded together with lead. Aluminum is actually an upgrade from stock. And when you say 3 row metal.. .you are still talking about aluminum. I dont think there is any metal out there with a higher specific heat(look that up fro non physics geeks) than aluminum.

walker, sorry I don't agree. the stock TJ (at least mine and a few of my buddies) have part metal (aluminum) wtih the top plastic seal being clamped on to the rest of the rad. I had problems with mine because it was leaking rad fluid out of the seal where the plastic and metal (aluminum come together. I found it pretty necessary to replace mine with one that is complete.

4X4, maybe an electric fan would be something to look into?

I made the same assumption when I got my Jeep back in March. However, I was cleaning the engine compartment a couple of months ago and I made the discovery the radiator had plastic end caps. I assume it's the original radiator since my Jeep has only 40K miles.

A 2 row or 3 row will not cool any more efficiently than the stock 1 row aluminum radiator. In fact, several people (but not all) have had cooling issues after putting in a 2 or 3 row radiator that were solved by going back to the OEM one.

It sound to me like you are having another problem. My first guess would be the fan clutch starting to go. I would recommend making sure the radiator is clean (especially between the AC condenser and radiator), the antifreeze is good (clean) and the correct concentration (change it if it is still the original antifreeze- and use distilled water), and maybe change the thermostat if it is the original one.

X2 - do the maintenance routines first (if you have not done them already) before you spend your cash too fast.... Hate to see ya replace a perfectly good radiator just because of too many flies and mud stuck in the fins or a bum t-stat. Make sure you use a high quality fluid that contains H.O.A.T. and mix it 50/50 w/distilled water.

If it came with aluminum radiator stay with that type they cool much better than the old style brass and copper if you can get away from the plastic tanks they will leak eventually but it is only a gasket the problem is recrimping the thing so it won't leak. I imagine some of the YJ's and CJ's probably have the brass style and they work great stay with that if you have it easy to solder and last a long time. But if it came OE alum it will not cool properly with a brass style.

x2 if it really is aluminum from the factory, leave it be until it leaks. Nothing cools better than aluminum.. again because of aluminums high specific heat. More cool air across the fins is the answer.. so my recommendation is an electric fan as well.

for all aluminum?? When I punch in the info it only lists 2 radiators for a 00 and both are all metal. I've got a buddy that wants an aluminum radiator and most options are upwards of 500 bucks. He won't listen that my dinky little 3 row with a Taurus fan cools my V8 with no problems.

that taurus fan and a 3row will cool at least 600 horse power motor with no problem

that aluminum is just like whats in the jeep but its aluminum it has to cool a little better
