I don't know about removing the the 4th gen model (I have a 2011) crank bolt but I suspect it is the same bolt as always used on the J engines. I recently had a timing belt service done on this low mileage but 11 year old van and I had them install a new crankshaft pulley (harmonic balancer) with fresh rubber while they had the old but still good one off. Reason being, just in September, on my 2000 LX (2nd gen) I had the pulley come apart at the rubber seam and shed the drive belt. Let me relate some experience I had with the Honda crankshaft pulley bolt, otherwise know as the BOLT FROM HELL and my waste of money on some tools. By the way, the dealer quoted $660 to do this job. Removed the right front tire and partially pulled back the wheel well plastic cowling. I started with my 1/2 drive Harbor Freight Earthquake air wrench. Would not budge it. Disclosure: I am only feeding it air from a Craftsman 30 gallon compressor through 3/8" hose which is good enough for lug nuts and even axle nuts. Wasted $70 on the Ingersoll Rand 19mm special socket designed for this job-did not work. Wasted another $20 on an OEM (AutoZone) heavy duty special socket designed for this job. Didn't work. Bought the Honda hex hold down tool and tried the air wrench and sockets again-no luck. Now remember, I am up on jack stands with not unlimited space underneath. But I bought a 25" HF 1/2" drive breaker bar sticking out from under the front bumper and using another 18" breaker bar to steady the hold down tool I couldn't break it loose, even with a floor jack on the breaker bar pushing up to the point the 1/2" drive bar was bowing badly and was likely to fail. Finally found a HF 3/4" drive Earthquake air wrench and bought it to give the gimmicky sockets another chance. I had upgraded my 3/8 inch air line to all new 1/2" hose and fittings, but it still didn't work. Side note: unless you have over a $1000 plus, 60 gal air compressor, your air wrenches are underfed and won't give you the advertised "nut busting" torque. HF (bless their heart) let me return the $360 big honkin' air wrench that I really don't need even for automotive lug nuts. So after relating this all to a Honda service writer who used to wrench there, found out that the dealership techs there use breaker bars to get that bolt off. So got on that jungle river site and I bought a manly 40" long 3/4" drive breaker bar made by Tecton (Taiwan), (2) 16" long 3/4" drive Crescent brand socket extensions (China), a 3/4" to 1/2" impact socket adaptor from HF(China), and my 1/2" drive Craftsman 19mm impact socket (USA). This will get you out past the fender. Got out the van's tire jack and sat it on top of two stacked pieces of scrap 6x6 to rest the whole contraption on, and put my whole 187 lbs. weight on it. Use mechanic gloves for this. First time, the holder slipped and gave me a little bit of whiplash. Repositioned that and gave it the old college try. This time it broke free with a loud pop. I think I heard my new awesome breaker bar chuckling during this. That was over 650 ft.-lbs. of REAL torque, not tapping from an air wrench. The bolt did NOT have Loctite on it as I suspected. Some vehicles you have to get a pully remover. The Honda one just wiggles off, hence the need for a tight bolt. Unless you want to spend $500 on the electric 700 series Milwaukee (which I hear is awesome but may not work on a stubborn bolt like mine) and you don't already have an air wrench, I would recommend you go with the same breaker bar/extension set up. It works! I ended up spending nearly the same but, except for the gimmicky sockets, now I have some great tools and upgrades to keep forever. And it was fun too...
