      Question Torquing Crankshaft Pulley on Automatic

      Very helpful forum.
      Recently replaced my timing belt, thanks to this forum. Everything went well except on reinstalling the crankshaft pulley bolt properly. I used an impact wrench to reinstall the crankshaft pulley bolt however I have no idea of the torque output of that wrench.
      Being an automatic transmission, pressing the brakes or any other suggestions to prevent crankshaft movement during torquing seems not to apply to automatics.
      Is there a special tool to use on the flywheel or similar to prevent crankshaft rotation?
      Is thread locking compound very effective on something like this?

      Thanks,
      JAH

      I used a chain wrench to hold the pulley while I used a breaker bar and socket for the bolt. chain wrenches are hard to find (where I am anyways) unless you have acces to a tool truck i.e. snap-on, matco, mac, cornwell. I got my chain wrench from snap-on I dont remeber exactly but I think it was somewhere around $100

      they sell chain wrenches at harbor freight, i should know, ive broken a dozen of them..

      you should have a inspection hole in the bell housing (possibly) that you can stick a larger screw driver to hold the teeth of the ring gear to stop the engine from spinning.

      i am pretty sure however the impact has it tight enough.. what ARE the torque specs though? (im not going to look).

      If I remember correctly once it is snugged down, you turn the bolt 30 degrees clockwise, then another 15 degrees clockwise, its been a while since I did mine, their may be a torque number before the 30 and 15
