Yes, a bad heater core can cause antifreeze to leak under the dash. The heater core is responsible for transferring heat from the engine coolant to the cabin, and if it develops a leak, coolant can escape and drip onto the floorboard. This can result in a wet carpet and potentially lead to further issues if not addressed promptly. Additionally, a leaking heater core can cause a sweet smell inside the vehicle and may lead to engine overheating if coolant levels drop significantly.
