AFTER THAT MANY QUESTIONS, SUGGEST GETTING SOME HELP WITH THIS REPAIR. YOU NEED TO BE PRETTY AUTO SAVVY TO ATTEMPT IT.
AND YOU MAY BE, JUST DON'T USE YOUR 5.56 ON IT IF YOU BUST A KNUCKLE OR TWO. BUT IF YOU PUT A CLIP OR TWO THROUGH IT POST IT ON YOUTUBE. FAN CLUTCH ALONE IS A TOUGH ONE!
GOOD LUCK, RUGER 223.
It's not that tough once you get the radiator and shroud out of the way. Autozone and advance auto both rented me the wrong tool to remove the fan clutch. It was the only one they carried. Oreily's had a universal set that worked fine. $80 but of course you get that back when you return it. and the bolts aren't too bad either
