Replacement radiator

I live in Mesa az and it gets really hot here. My radiator has a bad leak and I was wondering what the best radiator I could get for cooling my jeep better. Thanks

I don't want to spend over 300. So probably just going to go with the OEM and so a fan upgrade

Poison Spider hood vent installation would help greatly, especially if you have (or are planning on getting) a winch. I have a friend that has one on her JK and it does wonders. I'm getting one for mine since I have stock radiator, stock cooling, stinger, and winch and at highway speed, I get zero cooling through the radiator. It's an airdam with the winch but I've seen with the hood vent plate installed (cut holes in hood and install plate from Poison Spider), it DOES lower temps because it gives more airflow.

Just my $0.02...

Hood louvers will lower under hood temps a lot, but if you are looking for them to change engine operating temps you have other problems with your cooling.

What fan "upgrade"?

I know a while ago someone did a bunch of research using a fan and clutch from (I think it was an Explorer). That supposedly moved more air. You won't find an electrical fan that is going to move more air than the OE clutch fan (assuming it is working properly).

Be very careful with the wife mod. Uninstallation can be extremely expensive. Wife mods have been known to take the Jeep and all other mods during the uninstall process. Also, make sure you service your wife mod properly as often as humanly possible. Wife mods not properly serviced may malfunction or uninstall themselves at any time.

That's why I qualified that if the OP was considering, or had a winch installed, that's something that will cause issues with the cooling as well. Stock radiator, stock t-stat, stock fan, and the hood louvers will help with the cooling. If it's not cooling enough under the hood, the fan clutch will be engaged and then adding load to the engine which will increase op temps. I understand what you are saying, but that's not the point I was making. Yes, he has a rad leak, but just replace with stock and go with the louver installation.

Just what I've seen done, have experienced as effective to keep TJ running at normal op temps (This was experienced in San Antonio, Texas, not too much different temps than OP location), and rather cost effective.

Maybe something like a Warn Powerplant that has the compressor on top, maybe. But a normal winch shouldn't create a problem for a well functioning cooling system. Run a poll thread and see how many people with winches have issues and how many don't?

Then you have a problem somewhere that you need to fix, but an electrical fan isn't the answer.

As to the Explorer fan that was mentioned, experiences were mixed. Some people (myself included) tried it and were unhappy with the results and went back to stock. There were some people who stuck with it though I think.
