BMW Cooling System Parts & Accessories for BMW 7 Series E38 (1995-2001)

Clear BMW chassis

Please ensure your correct model is selected

The cooling system is arguably the weakest point in numerous BMWs. If you drive an aging BMW or plan on taking your car to the track like we do, we recommend beefing up your cooling system before going to the track. Generally, the main components in your cooling system that are prone to failure include the following: expansion tank, factory hoses, water pump, thermostat, fan (especially if your vehicle comes factory with a clutch fan), and radiator. Factory BMW expansion tanks are plastic and prone to either breaking off at connection points or combusting. As factory rubber hoses age they either crack or break over time - we offer silicone cooling hose upgrades for most applications to avoid future failures. If you have an older vehicle, your water pump likely comes from the factory with a plastic impeller - we offer upgraded water pumps with metal impellers that are far more reliable. Newer model BMWs utilize electric water pumps - BMW spent millions of dollars engineering these water pumps, but they fail so often that we recommend replacing at 60,000 mile service intervals to avoid being stranded on the side of the road. In terms of thermostats, we offer various upgraded thermostats for racing applications. If your BMW utilizes a clutch fan from the factory, we have several options available in terms of universal electric fans - we recommend replacing these to avoid sending brittle plastic fan blades through your hood. For radiators, we recommend swapping out your radiator for one that does not use plastic connection points like your factory radiator.

The oil cooler/heat exchanger for the automatic transmission is one of the most overlooked sections of the 540i and 740i cooling system. The cooler (heat exchanger) is a part of the overall cooling system and uses coolant circulated from the regular cooling system to cool the transmission oil running through this small cooling block. Some of the hoses are shared with the rest of the cooling system as well. The E38/E39 heat exchanger is located along the driver's side frame rail and is accessed from the wheel well. We recommend servicing or cleaning the heat exchanger along with any cooling system overhaul. Or if you're having transmission faults (especially for temperature) you may want to clean the transmission cooler anyway and these hoses will be a nice finishing touch.

Replacing or cleaning the heat exchanger components could lead to better shifting of the automatic as the cooler itself can become clogged. If you're experiencing harder or hesitating shifts, and the internal transmission temperature is rising without being regulated, the components in this system are the likely cause. Staying on top of the cooling needs of the transmission will help prevent a very costly transmission repair in the future. These hoses are easily replaced and you can clean the heat exchanger easily with brake cleaner and some brushes.

Included in this handy package are:
  • 11531711381 - transmission cooling hose from water pump to radiator (with t-connector)
  • 11531711385 - transmission cooling hose from radiator to cooler
  • 11531711384 - transmission cooling hose from cooler to water pump
  • 11537511207 - transmission cooling hose from cooler to chassis
  • hose clamp
  • o-ring


    This hose set fits the following BMWs:
    1999-2003 E39 BMW 540i
    1999-2001 E38 BMW 740i 740il

    A thermostat that opens sooner promotes better cooling in your vehicle. Running a lower temperature thermostat will keep everything much cooler. Keeping the engine cooler will help reduce and improve the life of the seals in your engine, saving you time and money, while also help increase engine performance. A tune might be required to gain the most from this modification, as well as to get your car's ECU accustomed to seeing lower temperatures.

    This is the viscous fan clutch for the for the engine fan on M60/M62 V8 engines. When the engine is cool or even at normal operating temperature, the fan clutch partially disengages the engine's mechanically-driven radiator cooling fan. This saves power, since the engine does not have to fully drive the fan. If engine temperature rises above the clutch's engagement temperature setting, the fan becomes fully engaged, thus drawing a higher volume of ambient air through the vehicle's radiator, which in turn serves to maintain or lower the engine coolant temperature to an acceptable level.Typically, when the fan clutch fails the car with tend to overheat at idle or in slow moving traffic.

    This radiator expansion tank (coolant reservoir) is used on E39 540i from 1997-2003 and E38 740i 740il 750il from 1995-2001. It is a common failure item. 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. This OEM Hella tank will give you a long life-span and will put your worries to rest of possible failure and coolant loss.

    Part of any cooling system overhaul on the 540i or 740i/iL should include a service for the automatic transmission heat exchanger (cooler). This block takes coolant from the radiator and uses it to cool the oil for the transmission. A blocked or faulty transmission cooler can lead to major transmission faults, harder or hesitating shifts, or even complete transmission failure. We recommend getting 2 new o-rings while replacing the the heat exchanger. il As part of every cooling system service we recommend cleaning or replacing the heat exchanger itself and the replacement of the hoses leading to it (see separate product).

    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:
    1999-2003 E39 BMW 540i

    This radiator expansion tank (coolant reservoir) is used on E39 540i from 1997-2003 and E38 740i 740il 750il from 1995-2001. It is a common failure item. 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. This OE BMW tank will give you a long life-span and will put your worries to rest of possible failure and coolant loss.

    As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts.  All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!
