ELI5: Why do cars make a ticking sound for a few minutes after turned off?

I'm a car guy myself, and even I don't really know the answer to this.

It's contraction of the various metal bits that were heated by combustion, and are now cooling. Sometimes that contraction causes an individual piece of the car to exist in either tension or compression, which is only alleviated when the force gets to great and something slips marginally. That slip produces the popping sound you hear.

You'll notice the same kind of pops if you have an oven range with resistive heating elements.
