Radiator problems of the 2008 Dodge Grand Caravan

Parts #4781537ac(connect water pump to radiator,made from metal) was purchased at napleton's Dodge (arlington height's ill ,60004) dealership at 05/07/2015. . Today middle of oktober 2015 and I must change this parts again because of antifreeze leakage(same problem was before) very costly !!!!!more over dangerous,can bring engine to overheat. Was lucky catch this at my driveway ,but if long distance or highway ,or on the middle of nowhere. . . . . . . . . . Should go back to mechanic and pay again for installation. . Why dealership sell same cheap parts as any regular parts store for higher price . . . ?.

I opened the driver side manual sliding door and then the horn started to blow constantly, the front and rear windshield wipers turned on, the hazard lights flashed, the reverse lights were on, the instrument panel had many warning lights on including a red dot on the bottom. I tried to hit my car alarm button to see if it would make it stop and it didn't. I closed the door as my son ran into the house and then all the doors locked. I had to use the valet key to open the door. I then pulled the hood release and opened the hood. The radiator fan was also on. I disconnected the battery so the horn would stop blowing. I waited about 20 minutes and went back outside and reconnected the battery and it did the same thing again. This time I tried starting the car and it started however it would not allow me to put it into gear. I tried to turn the engine off but it would not let me. I got out and then I removed the fuses to the horn so the noise would not disturb me or the neighbors. A few minutes later I got back into the car and it let me put it in reverse so I pulled the van out of our garage and into the driveway but the power steering did not work. I tried again to turn the engine off but it would not stop. I even moved the key to the off position and removed the key from the ignition and the engine continued to run. I disconnected the battery again but the engine continued to run as did the wipers and hazard lights. After about 10 minutes the engine finally shut off. This same type of incident happened before to us in 2012. . Read more...

There is a coolant leak coming from the y shaped diverter tube. The rubber has apparently been overheated due to its location over the hot engine. Many people have complained about this on forums. There needs to be a recall to have this replaced. The noxious smell of anitfreeze comes in through the vents, and smoke pours out from under the hood. Radiator is soon empty of all collant and the engine can overheat if not carefully watched. Coolant and water has to be constantly added in order to drive. This is clearly an issue with the placement of the tube over a hot engine and not insulating it well enough.
