I’m in the middle of replacing the aluminum radiator on my 12 jku with the 6.4 hemi swap, bought a new pwr radiator and I’m wondering if I should replace the fan too? I have noticed that when the fan is on high it kind of hum’s like it’s out of balance. Now that it’s off I’m noticing that it has a fair amount of play side to side and the 3 screws that hold it in place are tight. Is this normal? If not what’s a good replacement?
