BMW X4 antifreeze leak and non-working water pump issue on BMW X4

Some BMW X4 owners report experiencing antifreeze leaks and non-working water pumps, which can lead to significant engine problems if not addressed promptly. These antifreeze leaks are often associated with a failing water pump, but can also stem from damaged radiators, expansion tanks, or hoses. Symptoms of a failing water pump include leaking coolant from the pump's gasket or weephole, and visible liquid from the coolant pump, particularly in third-generation mechanical coolant water pumps. Ignoring these issues can result in inefficient cooling, potential engine overheating, and costly engine repairs. The repair process for a water pump replacement can be expensive, averaging around $1,100, so early identification of leaks is crucial to saving on future repair costs. After repairs, some owners find it beneficial to engage in post-repair maintenance to ensure their BMW X4 remains in optimal condition.
