Radiator talk!!!!

I was wondering if anyone had any advice on the matter!! The factory radiator in my 05' jeep wrangler X, I've noticed the temp during the summer time gets kinda high when I run my A/C. So I was wondering, I've been hearing all the talk about the stainless aluminum radiators I think by flexcool which are bigger capacity and allowing your jeep to run at cooler temps! Also was wondering if changing the old water pump mounted fan to the electric fan is worth doing aswell?┐?┐? Any advice would be much appreciated.

Thanks, Hostile JEEP T.J

I kinda doubt you've been hearing about stainless steel but you might have heard about aluminum core radiators which is the most efficient material so far as heat transfer goes. Actually, the OE (factory) radiator has an all aluminum core so it's a very good radiator so far as cooling goes.

To me, going to an electric fan is a step backwards. They don't usually have near as much air flow capacity, their biggest benefit is they can be shut off for water crossings so they don't damage the radiator while spinning under water as the OE fan can.

What leads you to believe your engine is running too hot? 210 is the usual temperature of the TJ engines, a little above that on hot days when running the a/c is not unusual.

Thank you Jerry , but I did say aluminum not steel lol, and my jeep is a little over 210 with my A/C in the summer but I just wanted to make sure I wasn't the only one! See I've had my jeep for about 4yrs now and for some reason that temp needle still causes a concern for me seeing that I was use to my street legal race truck I had never running hot like that, and I was pumping out over 400+ to the rear wheels! But thanks for the advice on the fan and radiator! Btw do u know if a good place thats reasonable to get one of those better radiators? My brother n law and I build custom rock crawlers and do lift kits and stuff for customers and they use them in those but most of the time there bigger and the clients actually bring us the parts like that and the engines they want to use, we fab everything else so I never know where they get them! It's my brother n laws side company and I just help him out all the time to learn more about everything!!

Gotcha, all I noticed was "stainless" which is associated with steel, not aluminum. Skipped right over the aluminum after I saw the word stainless. Just over 210 with the a/c on is perfectly normal and right where it should be. In fact, 210 without the a/c on is perfectly normal too, that is where Jeep designed it to run at.

You can't really get a better cooling radiator than the factory installed all-aluminum core radiator and since your TJ's temperature is right where it should be, I wouldn't worry about it at all.

There are aftermarket radiator manufacturers that make custom all alumium radiators but they are generally $400-500 and more but you really wouldn't notice much difference in your engine's temp.

x2 ...if your stock radiator and cooling system is in good condition and you haven't made any engine modifications that boost HP way up then the stock radiator and fan should be all you need.

Yeah sorry about the stainless part I just had a brain fart and used stainless in front of aluminum to describe the color! Like billet aluminum things like that is what I meant, but sorry for any confusions!!

I was having the running hot issue with the a/c on and on 95+ degree days I would run hot sitting at traffic lights. I replaced the fan clutch and problem went away. Check your fan clutch, the next time ya run hot switch the engine off, lift the hood and try to turn the fan by hand (with the engine switched off), if it spins easily the fan clutch is bad. You can get a heavy duty fan clutch at your local parts store for +/- $50.
