My stock radiator has developed a crack in the bottom and its got a decent leak. I'm wondering what's the best aftermarket radiator that'll keep my motor cool while wheeling in Colorado. I've heard a lot of good things about CSF. But I wanted to see if anyone else had good recommendations. Thank you!

 

Stock replacement. I put a Specter brand in mine 5 years ago still going strong. I think it was $70 at Auto Zone.

While you are at it you might aswell replace the radiator hoses. And if you dont know when they were last replaced, the thermostat and water pump too

 

I have had nothing but good luck with the mishimoto one. It was a little pricey though.

 

alright cool, yea that's a lot more manageable then a 350 or 400 "high performance" one. Would it work well with doing some heavy wheeling and hard trails?

 

CSF works just fine. Had mine in sence 2018 and no issues what so ever. Wheel in the hot *** western slope of Colorado and Moab all summer and don't even worry about the engine temps.

 

Im running a cheap high Performance aluminium eBay special cost like 130 bucks 4 ish years ago.. my xj runs cool even in 110 stop and go traffic. Eletric Fan almost never Kicks on but will if outside temp is high and its working hard.
this time of year 150 is pretty much the warmestcot runs.

renix coolant system was gutted and all fresh put in during radiator swap. Tstat, water pump and all lines replaced
