Coolant was running on to the floor and forward to the front passenger floor. Initially I thought it was a leak under the dash but traced it back to the rear heater core lines leaking. When I removed the right rear moulding everything was wet. I verified the leak by running the van and witnessing a leak in the lines at the press fittings. I will purchase new lines and replace them
