My car runs fine when I'm driving. Then when I turn off my car, there is a tapping noise in my piping. It's weird, it taps, then stops. It keeps on repeating on and off. But eventually it turns off. What can it be?????????????

 

lol
that's your radiator.. it's hot and it's cooling down.

 

lmfao, that is the gremlins in your car trying to get out.

 

there are little naked jawas hiding.
