I have a 07 Dodge 3500 Deisel that started to leak coolant off the right front side of the block. It does not leak all the time, you can drive it all day, does not leak. Leave it sit a day or so and it will start dripping off the right side of the block for a while and then stop.

The dealer said all they could find wrong was that the radiator cap was not holding pressure, need help thanks.
