Default Hissing noise after I turn off my car?

My car makes a hissing noise for a while after i turn it off, is this normal or is there some type of leak? it seems to run fine etc... no visible liquid leaks. Is this just a normal cooling noise?

If you are hearing that noise after you have been driving with the AC on, it is water dripping from the drain onto the exhaust.

The hissing sound is air coming back through the Tb after the car is shut off and there is no vacum anymore. Normal

Haha, a Cobra makes a hissing sound, that's great. Is the hissing coming from you expansion tank? (coolant) if so, oh no!
