Any help or ideas to remove this fill plug will be appreciated. Does anyone know the proper Allen head size? Can't drain it till I can fill it. Just got the CJ

The one on mine was a 1/2 inch square recessed hole and I just used a 1/2in breaker bar and some heat to loosen it up. I ended up replacing it with a plug that has a 1/2 in square head that I can get a wrench on
