Metal clacking sound after driving car

JMcLellan · 08-27-2024, 10:50 AM

Anyone else ever hear a sound like a couple metal plates lightly clacking together? I have heard this from my car when it's cooling down after driving it with the car turned off. It clacks once or twice when I have observed the sound.

I googled this and a couple themes I came across were the exhaust components, or brake rotors cooling down.

completly normal.... physics.. metal will expand when hot.. so when it cools down it shrinks and does some clicking sounds...
