Ford Edge misfiring and smell in car due to antifreeze leak after motor replacement on Ford Edge

Some Ford Edge owners report experiencing misfires accompanied by a smell of antifreeze following a motor replacement, which may indicate several underlying issues. A common concern is coolant leaking into the cylinders, leading to both misfires and the unpleasant odor inside the cabin. Additionally, some owners note that a failing heater core can also contribute to the smell of engine coolant, particularly when the heater is in use. Repairing these coolant leaks and addressing the misfires can be quite expensive, with estimates ranging from $8,250 to $8,800 for antifreeze leaking into the engine. Dealerships typically conduct diagnostic tests, including pressure tests, to identify the source of the problem and inspect components like ignition coils and spark plugs. In more severe cases, dealers may recommend an engine replacement if coolant is detected in the cylinders, with quotes around $8,300 for such a service. To effectively resolve these issues, it is essential for owners to have their vehicles examined by a qualified mechanic for accurate diagnosis and timely repairs to maintain the Ford Edge's safety and performance.
