Crackling / popcorn sound when I park.
 

My temps are all in line, but something under the car is making a boiling / popping / crackling noise after I turn it off. Doesn't require driving the car hard or anything like that. What is making the noise, and can I replace something to fix it? I'm worried there is transmission or differential fluid that is old or something and is boiling. I have a 6MT sport package.

i'm pretty sure its cooling sound and not something broken. mine does it too

There's a search feature here that's nice. Many threads on this issue. It's considered normal.

Completely normal. Enjoy the car..

Okay, it's normal. I can accept that. What is making the noise?

Ahh.....There's nothing quite like trying to diagnose a problem over the internet.

The Z's have a special feature when your oil temp rises, its cooking some popcorn. When it gets too high, you turn off the car and go to the back. Grab under the car and you have a fresh bowl of steaming popcor ready to eat. Seriously its the computer.. I think.

Exhaust cooling. Normal.
