So I've noticed lately that once my car is completely warmed up, a clicking noise comes from underneath the car around where the Y-pipe is. Its pretty loud/noticeable once the car is shut off and you get out, but not loud enough to really notice while driving unless your head is out the window at a red light. I was told it could just be the cats cooling off, but does anyone have other ideas as to what this might be?

Another thing I noticed a couple days ago is my car leaking water from the right middle of the car, a little behind the front right wheel. I'm pretty sure it's only when I run the A/C for a while, so is that just normal condensation? Still worries me a bit when I see a line of water coming down the driveway from my car.

Any ideas/input would be much appreciated! Thanks

 

Clicking and ticking under the front usually happens when hot metal parts start to cool off. Might be your issue, but I don't think you'd hear it at a light with the car running.

And the AC drain is right where you described. That water is normal. Worry if you don't see it.

 

not sure about the clicking noise. But the only thing that will leak clear water is condensation from your ac line.
