How to Turn Over an Engine by Hand | Bar Over an Engine

This is a full tutorial on how to perform an engine rotational test! It is super easy and essential on telling the health of your engine's rotating assembly.
Locate the front of the engine, down low, there will be a harmonic balancer which will have a serpentine belt attached to it. In the center of the balancer is a large bolt which will very in size depending on the manufacturer, usually between 22mm and 24mm.
You may need to remove the front under shield of the to access the front of the engine.
Attach a socket to the bolt and a short extension which should be 1/2 drive to help handle the force needed.
Connect a breaker bar which is a long bar socket wrench for leverage and turn the engine clockwise only. You don't want to turn the engine backwards because the timing chain tensioner can retract and the engine may jump time.
Continue to rotating the engine for two complete 360 degree rotations to ensure the engine is free and clear, then you are all set and the test is complete.

If you suspect that you have water sucked in through the intake which ended up in the cylinders. This will help expunge any water. As he said in the video, water will not compress so it can bend a piston rod or blow rings out
