radiator hoses get hot. Both heater core hoses get
hot. Thermostat is new and working. What am I

Same thing on my 2002 jeep liberty sport. And I know a lot of jeep liberty owners with the same problem.


I'd think it is still in the climate control blend door actuator or the door assembly itself. Sound like outside air still being directed in.
