hissing noise?

I didn't really notice until recently but when I park my car after driving 10-15 minutes I hear a hissing noise coming from the front of my car. Is this normal?

Re: hissing noise?

yeah, it kinda does. One thing I've noticed is that it really doesn't do it much unless I've run the A/C at some point during my drive.

What year? Mine does it also, but only after the AC has run.

'08 V6. It may just be condensation on hot pipes I guess. I'm not going to worry about it, but I'm definitely going to monitor it.

Re: hissing noise?

I think it's fine and most likely normal.

It's just the condensation. Still freaks me out on the Cobra because I rarely run a/c so I'm not used to the sounds.

Re: hissing noise?

At first I was afraid it was my tire! (I just patched a leak recently)

Re: hissing noise?

Both my Mustang & F150 do it, especially on humid days...which, this is Mississippi, so it's ALWAYS humid...

Re: hissing noise?

Yeah, Oklahoma's always really humid, especially the last few days. I bet that's the problem.

Re: hissing noise?

if its a 94-04 v6 it might be the AC dripping on the headers and the steam is the noise you hear. This causes cracks on the headers FYI lol (not all the time but it can happen so if you get an exhaust leak check the header for cracks)

Re: hissing noise?

Well, mine's an 08 so I think I'm okay, but I'll watch out for that anyways!

no worries, it's the liquid running through the a/c lines, it also does it on the refrigerator and a/c unit in your house, if you unplug the refrigerator while its running it will make the same noise.
