It was a easy use but impossible without job without it. If you are doing a water pump must have it

Metal is good and sturdy. Socket is 3/4 so you will need a reducer to use a 1/2 breaker bar.

The socket fits a little loose on the bolt but it may be the bolt that is worn. Haven't used the flywheel locks.
