The auxiliary heater hose connections (that are routed to the rear heater under the vehicle) can develop coolant leaks.

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
