Here's an odd question for you car mechanic people
So, I did some searching online and couldn't find my answer... I searched on TFP and couldn't find anything either so here goes:
Why do cars make that tick noise after you turn them off when they've been running? |
The ticking noise that you hear is the sound of the metal contracting as it rapidly cools, that's also why the ticking slows down quickly and will then stop.
|
LL has it right.
|
Why thank you, sir. I've always wanted to know what that was....
Metal generally doesn't contract that much... but I guess it's enough from the separate parts. Good info, thanks. |
I always figured it was that. Thanks.
|
Newer cars do it alot, due to them having so many friggin heatshields on everything.

An SC400 i drove for a while ticked like crazy when you parked it. we finally realized it was the brake rotors cooling down. We were always goin like 120 100yds before the driveway.
