no hot water going to heater hoses

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Liberty. Since you've already replaced the thermostat, water pump, radiator, and heater core, the issue may lie in the flow of coolant. First, You should check if there is a blockage in the heater hoses or any air trapped in the system that could prevent the coolant from circulating properly. Ensure the system is completely burped. This process can often take more time than you think. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
