WHAT MAKES THE CAR OVER 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 Murano. If your car is overheating even after replacing parts, the issue might involve trapped air in the cooling system, a clogged radiator, or a failing head gasket. An improperly bled cooling system can leave air pockets, which prevent proper coolant flow and cause overheating. A clogged radiator reduces heat dissipation, and a head gasket failure can allow combustion gases to enter the cooling system, leading to overheating and pressure build-up. The lack of heat from your vents could indicate that coolant isn't flowing correctly to the heater core, potentially due to air pockets, a faulty thermostat, or a blocked core. Another possibility is that an electrical issue is impacting the screen on your dash and the HVAC control system. 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.
