Fan Clutch Nut Won't Turn, Help!!!!!
I'm a newbie so please bare with me. I just purchased a 00 ML430 about two weeks ago and just after I got it inspected per Va state regs, the serpentine belt popped and broke the idler pulley. So in order for me to replace the idler pulley I need to take out a very long bolt which won't come out unless I take off the fan in front. I've bought the 2 piece fan clutch set with the 3 hole holder and wrench but no go. I've tried screw loose penetrating oil, heating the nut with a torch, using a mallet and hitting the wrench, no bulge! I think I've rounded the nut some as well with all the attempts. I'm open to suggestions.

You need a better wrench. And leverage. The wrench in that kit looks really cheap. Get a better wrench before you round the bolt and have to try to grind it into a square or grind it off. Add a pipe to it as a breaker bar. One person holds the holder. Other person uses the breaker bar and wrench to loosen the bolt. Wouldn't hurt to add leverage/pipe to the holder and have that person pull the other direction. Wear gloves with grip, and heavier padding so you aren't scared of mashing your knuckles. Worst case scenario get a 8 foot pipe, take the hood off, get a ladder, and get real leverage.

Take it to any garage/gas station and ask them to use an air chisel on it to break it. They will loosen it in one min for a couple $$. Also make sure you're going in the right direction.

The lip on the idler bolt wouldn't let me wiggle it out so I ended up cutting a very small piece out of one of the fan blade and slid the bolt out. Replaced the pulley and connected the new serpentine belt and everything is back up and running. Thanks for all the replies!

I bought an air chisel but decided why chance it lol. Problem solved for now. If I do have to change the fan blade or clutch, I'll definitely pull the air chisel out and tap it lol
