The bolt for the crank sensor on a 2001 Jeep Grand Cherokee is indeed 11mm in size. Make sure to use a socket or wrench that fits snugly to avoid stripping the bolt. If you need a replacement, you should be able to find one at an auto parts store or online, typically listed under crankshaft position sensor bolts for your vehicle model. Always double-check the specifications to ensure compatibility.
