Engine running a little hot or is the temp gauge not telling you anything? The thermostat might be the likely problem. Many cooling issues start with the thermostat. This is electronically controlled by the engine computer based on the cooling demands from the engine. And cooling components are working harder than ever. Engine performance is also dependent on temperature - as temperatures rise and pass a certain threshold the engine computer will begin reducing power. Stay on top of your cooling maintenance by replacing critical components preventatively. This replacement thermostat fits many of the N51 N52 N53 N54 6 cylinder engines and is an OEM Behr part. 

The thermostat is located along with the water pump on the side of the engine. To gain access for removal you may need to remove the water pump as well. If the water pump is removed you MUST replace its mounting bolts. You can add them from the options below. We also have a bundled package that includes the water pump, mounting screws, connecting hose, and clamps if you want to replace everything together (recommended). 

This thermostat fits the following BMWs:

This radiator is the OEM direct replacement for the stock radiator in the 135i, 335i, 335xi, and Z4 35i. Keeping your N54 or N55 at peak performance means including your cooling system in your regular maintenance schedules with the radiator, water pump, and thermostat being the primary components needing replacement. Not only can a failed radiator leave you stranded, but the sophisticated engine electronics will limit engine operability if temperatures reach a certain level. So having an efficient and fully functional cooling system is critical not only for safety but for performance as well. Don't wait until it's too late!
