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.

    Leaking from the rear heating line. Dodge has a recall only for 2004-2005 models to replace with aluminium lines. Cost $600 to replace the all rear line system.

    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....

    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.

    I'm having anti-freeze leaking. I don't know how much it is to fix so until I can save some money, I just keep filling the antifreeze daily. I'm on 100% disability and a single mom so I don't have money laying around. Figures though, I just finished paying for the vehicle about 5 months ago.

    I took it to a garage and told me my evaporator was out and would cost me $1500 to $2000 to repair or could could try sealant to plug leak for $25 with no guarantees. This worked for couple years and then went leaked again. Tried to plug again with no luck. We purchased a new front evaporator and installed...had it checked for leaks and held charge so finished charging and rear evaporator that point went out as well. We have not yet repaired due to cost. This is the 3rd pre-owned Grand Caravan I have had and this is first time I ever have had the problems I am having now.
