Not. Sounds like it's trying to make some though. This happens randomly, like tonight i went to park my truck and before i put it in P, it sounded like it a coffee pot running. Put it in park and it goes away a little bit. (i back in, the sound was in reverse) so i put it in drive after i was sitting still. Makes the noise again. Clutch issue? idk.

Lets try and figure out do you have a automatic or a manual transmission and proceed from there.

I agree with wyoming, if you have an auto tranny, you don't have a clutch. Is the sound coming from behing the dash? Possibly air in the coolant system?

It's an auto. What makes you think it doesn't have a clutch... ? All of them have clutches. And it's behind the dash

You hear fluid bubbling?

Heater core is behind the dash. Maybe you got air in it? Or a leak?
