NOTE; This DIY is only for V6. do not try it on 4cyl



Aim: Get that f@%king tight bolt off

Required: Air Compressor, Decent Air Impact Gun, ( or an Electric Impact Gun ). 17 or 19mm socket, 1/2 inch Breaker bar, Big ass bar.

There is no pics for this DIY, just a video. I felt you cant describe this in pictures.

Step: 1 support the engine from the sump with a Jack, undo the top engine mount to allow the engine to be lowered so you can access the pulley.


Step: 2 remove the splash guard to gain access to the pulley.


Step: 3 first try to undo the crank bolt from with the rattle gun, you never know you might get lucky. you will soon find out that it tight.

Step: 4 disconnect the Coil


Step: 5 place your socket on the breaker bar, place the socket and bar on the crank pulley, turn the engine clockwise till you hit the lower control arm.

Step: 6 Secure the bar to the lower control arm with some rope as shown in the video. the bar will want to turn clockwise so factor that in so the control arm will stop the bar from wanting to turn, not the rope. the rope is only added to stop the bar from moving about.

Step: 7 crank the engine for about 2 seconds, or just enough to loosen the pulley bolt.


Step: 8 You can now undo the bolt by hand. Reconect the coil



NOTE; This DIY is only for V6. do not try it on 4cyl


NOT RECOMENDED FOR NSX, use the correct tool.
