I'm sorry but havent' you owned a car before??? I am only 20 years of age and I feel like that's pretty common sense that a car kind of ticks and makes noise after you turn it off when it is fully warmed up... it's just metal contracting and nothing more. Go drive!

 

how about that tick tick noise while you are at a stoplight?

 

i know how that sounds like when the engine turned off..

it's more louder than that

and also at the stop lights..

 

Coulda fooled me
