BMW Cooling System Parts & Accessories for BMW 1 Series

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.

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.

This is the radiator drain plug (petcock valve) for manual transmission E82 and E9X models. The plug actually has two drains built in - the traditional blue petcock valve which is part of the black hex plug. If you drain the coolant from your radiator through this plug you could be in for a nasty surprise. The black hex plug has tabs that lock it into position in the factory BMW radiator. Once it's installed the tabs lock in place. But if you remove the black hex the tabs snap off and the plug will no longer seal correctly! Do not drain your coolant without having one of these on hand as a spare! It's cheap insurance on a definite leak later on.

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.

Fits auto transmission only.

Note: the Behr OEM radiator that we sell does not use this same drain plug. It has it's own drain plug that does not use the tabs. You won't need the factory BMW drain plug ever again.

The thermostat regulates the temperature of your coolant. At a predetermined temperature the thermostat will open to let coolant flow to the radiator and be cooled by airflow or the fan. Over time the thermostat will become stuck open or closed, leading to a variety of issues. A closed thermostat will never allow the coolant to reach the radiator and be cooled. Hot coolant will continue to circulate through the engine and absorb even more heat until boiling and the system overheats. An open thermostat is not as bad but is still not ideal - the coolant is always cool, with the temp needle always reading in the cool range. This tells the ECU to richen the fuel mixture to bring the car up to normal operating temp. So your fuel mileage decreases and the car runs rich.   

Replacing the thermostat is an easy but messy job. This thermostat includes the main o-ring (but a housing gasket may be required). Consider replacing the housing and any associated temp sensors while you're in there. The cooling system will need to be bled after.  

For vehicles with plastic thermostat housing

This Genuine BMW radiator expansion tank (coolant reservoir) is used on many BMW's with the N20, N51, N52 and N54 engines. 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.

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.

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 N55 6 cylinder engines and is an Wahler 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).

Manufacturing OE-grade replacement cooling parts is Wahler’s specialty. When you need to replace a component in your vehicle’s water system, high grade, and long-lasting parts from Wahler ensure the job is done properly the first time.

This coolant outlet hose connects the cylinder head to the thermostat housing and is a critical component of the cooling system. For many N54 owners, the "Mickey Mouse" flange is a common failure point. This plastic connector is vulnerable to degradation from heat, exposure to chemicals, and wear over time.

If your outlet hose has failed or the cylinder head flange is leaking, it’s best to replace the entire assembly for a reliable and long-lasting repair.

Key benefits of the adjustable hose clamp include:

  • Maintaining a secure and leak-free seal in your BMW's systems.
  • Preventing coolant or vacuum leaks that can affect performance.

This is the radiator drain plug (petcock valve) for manual transmission E82 and E9X models. The plug actually has two drains built in - the traditional blue petcock valve which is part of the hex head. If you drain the coolant from your radiator through this plug you could be in for a nasty surprise. The hex plug has tabs that lock it into position in the factory BMW radiator. Once it's installed the tabs lock in place. But if you remove the hex completely, the tabs snap off and the plug will no longer seal correctly! Do not drain your coolant without having one of these on hand as a spare! It's cheap insurance against a definite leak later on.

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.

Fits manual transmission only.

Note: the Behr OEM radiator that we sell does not use this same drain plug. It has it's own drain plug that does not use the tabs. You won't need the factory BMW drain plug ever again.

The N5X family of engines marked the start of a new era for BMW. The all-new aluminum block powerplants featured a host of technical upgrades, aiding in power output, reliability, and performance. Among these technological advances is an external electronic water pump, which removed load from the engine's accessory drive and allowed for advanced pulse-width-modulated (PWM) control.

From factory, the N52's electronic water pump is limited to a measly 200W output—strong enough for daily driving, but lacking in performance applications. Recognizing this shortcoming, ECS engineers set out to create a high-flow water pump upgrade that doesn't break the bank. Their high-quality adapter wiring harness and bracket allow you to install a 400W N54 water pump without any modification, an effortless, yet effective upgrade that doubles the output of the factory water pump!

By increasing coolant flow capacity, the 400W pump improves heat extraction from the cylinder head and engine block during high-load operation. This added thermal headroom is particularly beneficial for modified engines, sustained aggressive driving, track use, or operation in elevated ambient temperatures where the factory pump can operate near its limits. Improved circulation helps maintain more stable coolant temperatures and reduces the risk of localized hot spots.

Features & Benefits:

Upgrades to the more powerful 400W N54 water pump for increased coolant flow and improved engine cooling efficiency Sealed adaptor harness ensures secure connections and optimal operation under demanding conditions The N54 pump's higher power output offers longer-lasting, more effective cooling compared to the stock N52 pump Design:

40A fused power wire safely handles the increased power demands of the N54 pump, providing consistent and stable performance Sealed and robust construction, designed to withstand heat and moisture, ensuring reliability in even the most challenging environments Plug-and-play compatibility is designed for easy integration with the N52 engine and N54 water pump, minimizing installation time and complexity Kit Contents:
