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

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.

This packages covers the major components you would install along with a new water pump or thermostat. On the N51/N52 cars (128i, 325i 328i, 330i, 525i, 528i, 530i) the water pump and theremostat are mounted together. In fact, to get to the thermostat, BMW expects you to remove the water pump. This package covers the whole job. With the electric water pump now an integral part of the efficiency and performance of the engine, staying on top of its maintenance and replacement is the smart thing to do.

Our water pump/thermostat overhaul includes:
  • OEM electric water pump, p/n 11517586925.
  • aluminum mounting screws for water pump (set of 3), p/n 11510392553
  • OEM Behr thermostat, p/n 11537549476
  • Original BMW connecting hose from thermostat to water pump, p/n 11537521049
  • OEM-style hose clamps for hose (x 2)

    The water pump on the N52 engine has more cooling responsibilities than ever before. Not only must it provide cooling for the engine, but it's also pumping fluid used to cool the automatic transmission oil. The good news is that the pump only works when, and only as much, as it needs to. The engine computer dictates how much fluid needs to be pumped through the system depending on the load. That means the system can actually stop the pump when warmer temperatures are needed. No longer is the pump spinning all the time from an engine-driven belt. The bad news is that it's now an electrical part, so a failure is usually immediate and with no warning. And if the electronics are at fault, there is no way to rebuild or repair it. Fortunately, the engine computer will force a shut down or reduce power if a problem occurs, preventing catastrophic engine damage.

    How to avoid a water pump failure in the future? Replacing the water pump as part of a regular interval schedule will ensure you always have a functioning pump in place. Since this technology is relatively new for BMW, therefore the lifecycle of the pump isn't yet known, we have been recommending replacement every 80-100k miles. This package of OE/OEM parts covers everything with Original BMW coolant offered to finish off the job. A proper bleeding procedure must be followed with the new electric pump.

    This water pump package fits the following BMWs with the N51/N52 engine:
    2008-2013 E82 BMW 128i
    2006-2011 E90 BMW 325i 325xi 328i 328xi 328i xDrive 330i 330xi - Sedan

    This cooling overhaul will cover just about everything you could replace on the 325/330's cooling system. We start with the basic water pump and thermostat bundle. These are already vital to the health and durability of the N52 325/330i. But to properly maintain these cars for the long term, the rest of the cooling system must be refreshed and preventatively replaced. Here you can add a radiator, expansion tank, all of the 325/330 cooling hoses, and the BMW antifreeze. This package fits 325i/330i/xi with N52 engine and automatic transmission. Some of the components are different for the automatic models because of the auto transmission oil cooler.

    The sophisticated electronics of the ECU and water pump means catastrophic overheating should be a thing of the past. But the downside is that the electronics can shut down without any warning or symptoms. And troubleshooting is equally frustrating since the water pump electronics are not readable or serviceable. There are several clues to a faulty thermostat or water pump - the fan runs at full speed all the time (even immediately on a cold start), pending (soft) fault code for low coolant flow, or the water pump can be heard running constantly. But when the pump fails it's an immediate shut down of the engine which can be a major inconvenience and lead to additional repairs that might have been avoided with preventative maintance. We recommend a full cooling system overhaul on the E90/E92 every 80-90,000 miles and to check for soft/pending codes at every 5,000 mile service .


    Base Cooling Overhaul Package - Water Pump and Thermostat

    Includes:
    + Genuine BMW electric water pump, p/n 11517586925
    + mounting screws for water pump (set of 3), p/n 11510392553
    + OEM Behr thermostat, p/n 11537549476
    + Original BMW connecting hose from thermostat to water pump, p/n 11537521049
    + OEM-style hose clamps for hose (x 2)

    The water pump on the N52 engine has more cooling responsibilities than ever before. The good news is that the pump only works when, and only as much, as it needs to. That means the system can actually stop the pump when it doesn't need to be running. The bad news is that it's now an electrical part, so a failure is usually immediate and with no warning. The preventative replacement is your only insurance from a very inconvenient and costly breakdown in the future. Plus you get the very latest BMW water pump design with any improvements they've made since your original pump was installed.
    Cooling Hoses
    (click to expand)
    With regular driving the hoses should last a very long time. Even the plastic connectors seem to be holding up well. But as a preventative measure new hoses are recommended. We have also seen issues with re-using hoses as the spring connectors get weak over time and may not have the strength to hold the hose in place. They seem to have a tough time holding tension especially when they have been removed and reinstalled. In the interests of a thorough overhaul we recommend replacing these 325/330 water hoses during this job (see diagram):
    • 17127531579, upper radiator hose
    • 17127531581, lower radiator hose
    • 11537613176, water pump to engine
    • 11537534880, gasket for #176 hose
    • 11537545890, thermostat to cylinder head (includes new o-ring)
    • 17117524710, radiator to auto trans cooler
      There are other hoses too but they are not often replaced during a radiator swap (radiator vent hose and heater core hose) and they don't see much wear. We offer these as well if you want a complete set (see Additional Items at the bottom of the page).
    Expansion Tank Options
    (click to expand)
    The expansion tank on the 325/330 is not prone to failures (unlike previous 3-series cars) so a new one is not strictly required. There aren't many seams or stress points for it to crack and we haven't heard of too many issues. But we wanted to offer it as part of a complete overhaul in case you want to cover everything. Simiarly, the level sensor is not required unless you're getting erroneous 'low coolant' warnings from the dash/iDrive. We do strongly recommend replacing the cap because that is designed to be the weak point in the system. The cap is what regulates the pressure inside the system and it should be replaced every few years anyway.
    Coolant Temp Sensors
    (click to expand)
    There are two coolant temp sensors on the E90 325/330 - in the lower radiator hose and in the cylinder head. Both feed coolant temps to the ECU to regulate the water pump and cooling fan. You should replace the one in the lower radiator hose because it's one of the main sources for coolant leaks, especially when the old sensor is re-used in a new hose. The sensor in the cylinder head is not as prone to leaks and it's easily accessible so you don't have to replace it right away. But we offer it with the package in case you want to have a complete cooling system overahul.

    2006-2006 E91 BMW 325xi - Wagon


    Note: not for cars that have the dealer-installed auxiliary heating option. Some of the hoses are different with that option. It's not a very common option in North America (except in parts of Canada) but there are hoses that are specific to that option.

    Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

    To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

    This cooling overhaul will cover just about everything you could replace on the 328 SULEV's cooling system. We start with the basic water pump and thermostat bundle. These are already vital to the health and durability of the N51 328i SULEV. But to properly maintain these cars for the long term, the rest of the cooling system must be refreshed and preventatively replaced. Here you can add a radiator, expansion tank, all of the 328 SULEV cooling hoses, and the BMW antifreeze. This package fits 128i/328i SULEV with N51 engine and automatic transmission. Some of the components are different for the automatic models because of the auto transmission oil cooler.

    The sophisticated electronics of the ECU and water pump means catastrophic overheating should be a thing of the past. But the downside is that the electronics can shut down without any warning or symptoms. And troubleshooting is equally frustrating since the water pump electronics are not readable or serviceable. There are several clues to a faulty thermostat or water pump - the fan runs at full speed all the time (even immediately on a cold start), pending (soft) fault code for low coolant flow, or the water pump can be heard running constantly. But when the pump fails it's an immediate shut down of the engine which can be a major inconvenience and lead to additional repairs that might have been avoided with preventative maintance. We recommend a full cooling system overhaul on the E90/E92 every 80-90,000 miles and to check for soft/pending codes at every 5,000 mile service .


    Base Cooling Overhaul Package - Water Pump and Thermostat
    (click to expand)
    Includes:
    + Genuine BMW electric water pump, p/n 11517586925
    + mounting screws for water pump (set of 3), p/n 11510392553
    + OEM Behr thermostat, p/n 11537549476
    + Original BMW connecting hose from thermostat to water pump, p/n 11537521049
    + OEM-style hose clamps for hose (x 2)

    The water pump on the N51 engine has more cooling responsibilities than ever before. The good news is that the pump only works when, and only as much, as it needs to. That means the system can actually stop the pump when it doesn't need to be running. The bad news is that it's now an electrical part, so a failure is usually immediate and with no warning. The preventative replacement is your only insurance from a very inconvenient and costly breakdown in the future. Plus you get the very latest BMW water pump design with any improvements they've made since your original pump was installed.
    Cooling Hoses
    (click to expand)
    With regular driving the hoses should last a very long time. Even the plastic connectors seem to be holding up well. But as a preventative measure new hoses are recommended. We have also seen issues with re-using hoses as the spring connectors get weak over time and may not have the strength to hold the hose in place. They seem to have a tough time holding tension especially when they have been removed and reinstalled. In the interests of a thorough overhaul we recommend replacing these 328 SULEV water hoses during this job (see diagram):
    • 17127531579, upper radiator hose
    • 17127531581, lower radiator hose
    • 11537613176, water pump to engine
    • 11537534880, gasket for #176 hose
    • 11537545890, thermostat to cylinder head (includes new o-ring)
    • 17117524710, radiator to auto trans cooler
      There are other hoses too but they are not often replaced during a radiator swap (radiator vent hose and heater core hose) and they don't see much wear. We offer these as well if you want a complete set (see Additional Items at the bottom of the page).
    Expansion Tank Options
    (click to expand)
    The expansion tank on the 328 SULEV is not prone to failures (unlike previous 3-series cars) so a new one is not strictly required. There aren't many seams or stress points for it to crack and we haven't heard of too many issues. But we wanted to offer it as part of a complete overhaul in case you want to cover everything. Simiarly, the level sensor is not required unless you're getting erroneous 'low coolant' warnings from the dash/iDrive. We do strongly recommend replacing the cap because that is designed to be the weak point in the system. The cap is what regulates the pressure inside the system and it should be replaced every few years anyway.
    Coolant Temp Sensors
    (click to expand)
    There are two coolant temp sensors on the 328 SULEV - in the lower radiator hose and in the cylinder head. Both feed coolant temps to the ECU to regulate the water pump and cooling fan. You should replace the one in the lower radiator hose because it's one of the main sources for coolant leaks, especially when the old sensor is re-used in a new hose. The sensor in the cylinder head is not as prone to leaks and it's easily accessible so you don't have to replace it right away. But we offer it with the package in case you want to have a complete cooling system overahul.

    Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

    To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

    See kit contents below for all included components.

    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.

    When it comes to BMW's we all know the weak point is commonly in the cooling system, many models proving hard to bleed the air pockets out after the refresh. The coolant refill tool solves this problem, ensuring that you get an air pocket free fill. The entire task is as simple as draining the system like normal, reinstalling the drain plugs and hooking the tool up to your refill location. The reason this tool works so well is due to the venturi valve, it converts air pressure from the compressor to vacuum inside the cooling system, then with a twist of a valve sucks coolant right into the system using the vacuum pressure.

    When it comes to cooling system hose replacement, the "U" shaped hose connecting the water pump to the thermostat is usually the first to fail. A lot of this comes from its close proximity to the hot downpipes, while some of this failure comes from the sharp bends in the hose. 

    Why not upgrade when you're due for a replacement? The ECS Tuning silicone hose replacement fixes these issue with two key features in their design. Offering this hose in a much more heat resistant silicone instead of OE rubber and having the hose wrapped in aluminum. The aluminum coating acts as a heat shield to further protect the silicone as well as reducing the temperatures forced on the coolant running through the hose. 

    Replaces OE hose #11537545665

    Some of the biggest issues when owning a BMW can come from cooling system components. Even through years of improvement, the same failure is seen with the plastic fittings and adapters from years of hot to cold temperature fluctuation. The N52/N54/N55/N20 engine sees failure at the plastic cylinder head outlet adapter connecting the cylinder head to the thermostat hose. The stock plastic adapter simply shears off at the end of the barbed fitting, creating a massive coolant leak. The engineering team at ECS Tuning decided a billet aluminum piece was a much better option to contend with the temperature fluctuation. Since other offerings on the market want you to modify your OE hose to be reused, they even developed a silicone replacement hose. These 2 pieces can be purchased separately if you decide to reuse your existing OE hose or in a package kit together for a single click upgrade. Features: Manufactured from billet 6061-T6 with type III anodized for exceptional durability and corrosion resistance. Much stronger part than OEM plastic ​​Will not become brittle and fatigued over time due to thermal cycling. This will prevent the part from breaking during removal and re-installation. Follows OEM form for perfect fitment. Utilizes (and includes) OEM O-ring 11537545278 to ensure a proper seal. Recommended clamp size is 25-40mm

    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:

    If your vehicle is experiencing cooling issues, chances are the thermostat is the cause. Common symptoms include a prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance and potential damage to vital components in your vehicle.
