Planning a preemptive replacement of your water pump and thermostat is a smart move. Because the pump is electric, when it fails it does so completely and without warning. We strongly recommend replacing the water pump within 80,000 miles. This package covers the pump, thermostat, and minor hardware.

If your hoses are only a few years old they may not need to be replaced. However, the spring clip wears out over time and re-using the hose with the old clip may not have adequate tension to seal. See the links below for a selection of related hoses.

BMW coolant is sold separately (or purchase it locally to save on shipping).

This package is made up of OEM or Genuine replacement water pump and thermostat parts for the 2012+ models with the N55 "twin-power turbo" engine. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. These parts have a two year warranty.
