I'm a firm believer that the radiators, that came with the 3.6 is not up to snuff. Does anyone make a larger capacity radiator? I know people have talked about larger radiators having to be put in Wranglers, that are produced in Arab countries, due to their higher temps year round, and higher standards put on their vehicles.

Just checked - Mishimoto doesn't offer one, so we must not need it! 😉

What are the 392 guys running - it's sure to be bigger & made to mount in (kinda?) the same place ...

I believe Jeep JL radiators are a one size fits all kind of deal between 2.0,3.6 and 3.0 engines. I think the difference is with the CFM rating of the electric fans (3.6 has the smallest CFM rating). I'd say 'if' it were possible to get an electric fan/controller from a 2.0 and have it work with the 3.6 PCM......then you'd have some improvement over stock.. Also, you can get the grill inserts from a 2.0 to improve air flow ahead of the radiator at highway speeds.

Never had an issue with heat in either of my 3.6’s. And one was frequently loaded down with all our camping gear going through the Rocky Mountains for 7 years and 220k on the clock, original rad too lol.
