Made in-house to lock the flywheel when replacing the cambelt. Allows correct torque to be applied and prevents a loose crank pulley.
Note . It is not adviseable to use an impact gun to retighten the crank nut, this is often the cause of loose pulleys. Lock the flywheel and set the bolt at the correct torque.
NOTE this is for the 1.8 engines and won't fit a 1.6.or an auto box.
