The plastic cover on certain BMW engine water pumps is known to crack over time and cause the pump to leak coolant. If you need to replace your pump, you don't want to run the risk of it failing that way in the future. This Dorman OE FIX solution upgrades the pump housing and hardware to robust aluminum to help extend service life. It also has an updated circuit board design that increases reliability. This improved replacement has undergone rigorous laboratory and on-vehicle road testing, proving it matches OEM performance. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment.
