why do hot engines “click” when turned off?

401 views

After driving for a little while, you turn into a parking lot, park your car, turn it off and get out. Then you hear the engine making clicking sounds. It only does it when it’s hot, does it have something to do with metals expanding when they’re hot or?

Different metals/materials expand and contract at different rates when heated or cooled. The clicking is just the parts doing their thing.
