The housing is only held on by three bolts. If one of them was slightly loose that could be part of your problem. There is a line running to your heater coming off of the back of the housing, down near the trans. You can get to it without removing everything, but it takes a little patience, especially if the guys at the factory put your clamp on kinda sideways.
The other visible hose comes off of the front. Very easy to determine if it is leaking.
Whatever you do, DO NOT break that housing. List on it is almost $40.
