Dodge Grand Caravan Underbody Coolant Leak

(108 reports)

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.

the rear heater hoses are leaking on the passenger side of my caravan i looked under an seen the problem. the two hoses that rout down from the fire wall are rusted mid way of the line. so if any one has some kind of solution that can be helpful . thanx -
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.... -

car overheated & had to be towed to dealership. rear heater hoses required replacement, as well as thermostat. As I told vehicle was ready, I picked vehicle up on Sat. (today) and now they tell us new problem detected during test drive, vibration. Dealer advised us 4 motor mounts are broken and need to be replaced. Drove home and note severe vibration, will not drive again until fixed. Why when it was brought to dealer was their no vibration. Now we have 4 broken motor mounts which will cost $1200 plus to repair? -

Today I noticed a small drip begin. It is this part that I am reading about. It happened on a day when it was -25. Thankfully it was not a large leak, and was caught early. I do live in an area that uses road salt in the winter. It will be repaired by a friend who know ls how to do car repairs. It is the metal hose that runs under the van. -
Had to have it repaired, serious leak under van, cooling was never working correct -
I am losing coolant and can not find the leak and my heater is not working. I have replaced the aluminum heater lines that run along the firewall because they were rusted out. Now I am not losing as much coolant but I still have to add collant but its about every 2-3 days rather than daily. -
Started noticing the exhaust pipe just after the cat was heavily saturated. After further inspection I noticed it was a leak coming from the lines mounted above it (Rear heat/ac lines) The liquid is definitelly coolant. I have not repaired the problem just yet but will within the next week or so due to the fact that I am slowly but surely losing coolant and it is rusting the exhaust pipe rapidly. -
