Hi Mike & All,
I just installed one myself.
I just cut the 3" section out and held a bucket underneath.
Found that not very much coolant came out.
Regardless, put a piece of plastic topped with an old towel underneath
to keep the coolant off of your carpet.
But... Man did it make a difference on my 3000 mile trip
through the UT, ID, Eastern OR. Desert!!
I didn't get the A/C fixed in time
but, I did have a cool draft on my legs
And no toasted feet !!!

best,
John C...
59 yrs old and will die at the age of around 32 !!!!
that's my story & I'm sticking to it !!!  :o)
