This is the coolant temperature sensor used in many BMW models from the mid-1990s to the mid-2000s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer.

This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement.

This coolant temp sensor fits the following BMWs:
1996-1999 E36 BMW 323is 323ic 328i 328is 328ic M3, located in cylinder head
1999-2003 E39 BMW 540i, located on side of water pump
1999-2001 E38 BMW 740i 740il, located on side of water pump
1995-1996 E38 BMW 750il, located on side of water pump

We have found that the expansion tanks should be replaced based on age as well as condition. Expansion tanks seem to have a lifespan of less than six years before they show signs of fatigue and wear. Pre-emptively replacing the expansion tank as part of an overall maintenance plan can prevent you from getting stranded from a sudden failure later on. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future.

The OE plastic connector is a frequent failure point due to brittleness and cracking caused by repeated thermal cycling and hydrolysis. Hydrolysis, the breakdown of plastic or rubber by water exposure, weakens the structure over time, leading to failure. To combat these issues, Rein’s upgraded connectors are constructed from high-strength aluminum, eliminating the vulnerabilities of plastic connectors and ensuring long-term durability.

This radiator coolant reservoir/expansion tank for E46 M3 is a common failure item as the plastic weakens over time and stress crack will lead to coolant leaks. If your car has over 80k miles and hasn't had one of these replaced, we highly recommend it during your next major service. We have found that the aftermarket coolant reservoirs fail easier than the original BMW piece so we only offer the BMW type on this part.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This item fits the following BMWs:

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 of the engine. And cooling components are working harder than ever. Engine performance is also dependant 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.

We have found that the expansion tanks should be replaced based on age as well as condition. Expansion tanks seem to have a lifespan of less than six years before they show signs of fatigue and wear. Pre-emptively replacing the expansion tank as part of an overall maintenance plan can prevent you from getting stranded from a sudden failure later on.
