hi all, wonder if anyone can help me have a 08 chrysler voyager 2.8crd auto. i have been given an advisory on its test that the long coolant pipes that run under the drivers seat and run the length of the car need replacing but its like finding hens teeth, has anyone bought any and where. also my thermostat is wandering around and shows the car is heating up intermittently. i have had the system drained and flushed new coolant done, but still doing it, not quite as much though any advice greatly appreciated
