No. Driving with a faulty heater core can lead to several dangerous consequences. Firstly, it can cause the car to overheat, leading to engine damage. Secondly, if the heater core is completely blocked, it can prevent coolant from circulating properly, again causing the car to overheat. Thirdly, if the heater core is full of debris, it could be released into the coolant, causing further damage. Lastly, the heater core might catch fire, which could lead to the entire vehicle being engulfed in flames.
Therefore, it is not recommended to drive a car with a faulty heater core.
