Mishimoto Mechanical Water Pumps

Water pump failure is one way to ruin your weekend cruise or track day. Stay on top of your BMW's maintenance by replacing your M50/M52/M54/S50/S52 water pump before it fails and overheats your beloved inline six. The engineers at Mishimoto have developed a high-quality replacement water pump to continue supporting E36/E46 customers in every aspect of their cooling system needs. The mechanical water pumps feature a durable cast aluminum body and a composite impeller for improved durability. Debates over impeller material are not uncommon. The Mishimoto team determined that their composite impeller provides optimal durability in extreme conditions, while being less taxing on internal bearings compared to a metal impeller unit. Along with robust construction, a new water pump O-ring is included for hassle-free installation.
