2012 jeep jk looks good but does not fit at all
So i got this in November 2024 but since its been cold in germany i just now got to installing the radiator. It does not fit at all, also careful threading in the overflow because my ended up tearing in half and now the threads are stuck inside. 2012 jeep jk. Buy something else that actually fits.

Great Price for All Aluminum
I bought this radiator to replace the stock one which was leaking. 86,000 miles on my 2008 wrangler JKU. It is not an exact fit but if you do some trimming it will fit. The radiator pushes back into the engine compartment a little bit compared to the stock one. I would say 1/2 to 3/4 of an inch more. The fan fits but you have to trim the bottom aluminum hook the fan sits on as it is a little too wide to fit in the slot on the bottom of the stock fan shroud. I haven't had any leaks yet. I replaced the water pump, thermostat, radiator hoses, and antifreeze coolant at the same time. The job took me a little longer than I thought it would because of the trimming. It looks nice and shiney right now.

NOT FOR JEEP WRANGLER
Do not buy this for a Jeep Wrangler, unless you are able to modify mounting points, and want to buy new hardware. We were able to install it on the vehicle, after making semi-heavy modifications to the mounting points.

The fit was off a little.
The fit was off a little .The bracket for the a/c lines didn't line up.It is a little wider I had to trime and plastic on the top of the radiator. That said it has been in for mouths and is working great.
