AHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!I've done a search for the sizze and have broke many tools trying to get these bolts off. a 19mm socket feels too loose and a 18mm won't fit. I have tried a 3/4 also but the inside of the socket is just stripping. I have tried a impact wrench and a breaker car but i can't get the bolts to budge. Any body know the correct size of socket is used for the bolts so I don't keep breaking my tools?

Nevermind, I figured it out. they were 19mm bolts. I just used a breaker bar with three different pipes are extenders to break them loose. I also wedge the engine between my car and my engine lift so it wouldn't flip over when I was breaking the bolts.

Ah yes, I forgot about the bolts labeled MT and AT for the KA24E.

19-6pt. Will either take an impact or someone with some balls plus someone to crank. Given the amount of tourque, I would suggest using jamming a pipe against the ground.
