Winding down noise under hood when shutting car off
 

I've tried to figure this out on my own, but can only come up with two possibilities. When I shut the car off, I hear what sounds like a high revving component slowing down. I'm guessing either the fuel pump (which I have never heard on other cars before) or the DC motor for the VVEL. Anyone know?

I have no idea, but this is one of my favorite things about the Z. Sounds like a turbine engine shutting down.

the blue ones are transformers. mine doest this too. I call him sparky, he doesnt know i know he exists.

My going theory is fuel pump.


Better go check your garage.... Sparky may be escaping, now that he knows you know he exists.

my 03 350z did it and now my 370 too. ive heard it referred to as the "death rattle" lol... but nothing to worry about

could be the radiator fan

It's the secret alien technology turbine winding down. Pretty soon someone in a black suit and sunglasses will ask you to look at a little pen with a light on it and all these troubles will go away :)

I personally love the sound, its my rocket ship.

I guess we really have to break out the new technology in the new Nissan 370Z to really know what it has...I know with Toyota, sometimes after 15-20 minutes, you will hear a soft noise of a motor running for like 5-10 minutes...the vehicles have a computer system that once in awhile turns on to check all mechanical and electrical parts to make sure the vehicle is working properly...

With the new Prius, once the vehicle is turned of, you will hear engine still working while it draws the hot water from the car, and store it in a thermal bin so the next time you start the car, your car will have the hot water already. This is something deeply mechanical in the car that most salespeople learn but never pass onto their customer

I actually love this sound too lol, sounds like a plane switching off :tup:

Electric radiator fan.

I think its too quiet to be the fan.
