Just curious

Ive never had anyone specifically explain to me why diesels make the little squeak when u shutem off. Anyone have a technical explanation? Just trivial knowledge I like to know. Thanks in advance.

Little squeek?

Talking

It is the compression of the diesel motor stopping the crank from turning immediatly, with everything else still turning (all the pulleys) so you'll get a little squeak from the belt on the crank pulley when you shut it off. Hope this explains it for you.
