BMW Cooling System Parts & Accessories for BMW 3 Series E91 (2006-2012)

Replace the flimsy plastic bleeder screw used in the coolant expansion tank or in one of the cooling system hoses with this high quality, durable, aluminum bleeder screw. The stock plastic screw can deform over time due to heat or even regular use. We have even seen the head of the screw snap off, leaving the threaded body stuck in the expansion tank. This aluminum screw will help to prevent sudden failure of the bleeder screw, which can result in immediate overheating of the car.

ECS Tuning's Aluminum Coolant Bleeder Screw replaces Genuine BMW Part Number 17111712788

Due to the higher operating temperatures of these engines plastic components are more susceptible to failure. If you are overhauling your coolant system, now is the time to consider preventative replacing this expansion tank.

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).  

For the following BMW engines:
N54 N52
