No heat

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 vehicle. If you're getting no heat in your Versa despite a new radiator, heater core, and thermostat, and the bottom radiator hose remains ice cold, there might be a coolant circulation issue. This could be due to trapped air in the system, which can cause coolant to flow improperly and leave some parts cold. Try bleeding the air from the cooling system by letting the engine run with the radiator cap off until it reaches operating temperature, allowing any trapped air to escape. Another possible cause is a failing water pump, preventing proper coolant flow through the system. A clogged hose or blockage could also restrict flow to the heater core, resulting in no heat. 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.
