I agree with @chknkatsu in both the Mishimoto aluminum radiators being downright silly crappy - it's very documented on this forum that folks continually have them leak - quality assured or whatever reason. They have leaks reported all over for JKs .

I had read all about this issue before hand & consequently went with the OEM radiator but upgraded it with an aluminum shroud + a whopper Spal, waterproof mega fan .

'Dunno what OP is hoping to hear from this except maybe feel better knowing they ain't alone in this product causing grief...It's as if every 3-6 months some other JKOwner reports a spewing Mishimoto radiator ...

Do other aluminum aftermarket radiators leak like this on our model Jeep ?

(Edit: fwiw , I'm not striving to bash Mish ; I run thier overpriced silicone rad hoses and they're fine )

yeah, I always related them to Honda and Supra tuner cars before the jk radiator went to market ?

maybe their welds just aren't up to a jeep's vibrations or rough ride over long periods and crack the welds? I'd love to know if all these leak in similar vicinity or part of the radiator , not to flog a dead horse

sad part is there are also honda, supra, and evo guys complaining about chronic mishimoto leaks. even those guys consider mishimoto to be a low end brand
