Thank you for posting the pic! I was able to locate and identify both cowl drain bladders on my 2006 V6 Mustang. They were easily reached by hand and both pulled off easily. For those who haven't found them, they are 2 3/4" long and 2" high, black rubber, and they are removed by pulling down. Mine were not clogged, nothing except a bit of grime in each one, but the 'lips' on the bladder were together in such a way that any leaves or even dirt buildup would have clogged them.
