Coolant leaks coming from the underbody on vehicles equipped with rear heat/AC are common. The underbody hoses should be inspected as part of regular maintenance. If you drive on roads where salt is prevalent the problem is generally more severe. Some 2005 models are involved in a special service action, no government recall was issued.

    If you are experiencing coolant leaking from under the body of your caravan, you need to address this, before you lose all your coolant and your stranded and need a tow that will cost a few hundred.... There are coolant pipes that run to the back heater. These pipes will rust out. I believe I paid around $100 for the replacement pipes which are made of stainless steal. They are tricking to install, becaus ethey run from the fire wall down and under the body to the rear heater. Keep an eye out for this, it is only a matter of time....

    The passenger side of my van gets extremely soaked after it rains or after running the A/C? It seems to be a more common problem the more I reaserch.

    For several years now I smell hot coolant and several mechanics cannot find a leak. Coolant level does go down which confirms a leak and jives with the hot coolant smell. Noticed the metal pipe connected to the lower radiator hose is very rusted and corroded. Will look more into this area for the leak.
