BMW Cooling System Parts & Accessories for BMW 7 Series F02 (2009+)

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 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.

  • Wahler Thermostat
  • 1 liter of Coolant

With the Mishimoto Racing thermostat, the activation temperature becomes 74C. That's 23C cooler, meaning you can rest easy knowing your engine will stay cooler to help avoid all the problems that can be associated with an engine running hot.

If your water pump is starting to fail, you may notice coolant leaks, or even hear a whining noise coming from under the hood. If you think your water pump is starting to fail, replace it as soon as you can. The main downside to an electric water pump is you may also notice nothing - nothing but overheating! Keep your eyes peeled for warning signs it may be time to replace your water pump. N54 and N55 engines are prone to water pump failure - replace every 60,000 miles. Comes with electric water pump and installation hardware. Aluminum mounting bolts are one time use. Replace every time the water pump is removed.

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

Ensure a tight and leak-free seal in your BMW's cooling, vacuum, or intake systems by installing a new adjustable hose clamp. Over time, clamps can deform or lose their tightness due to aging or frequent removal, potentially causing leaks in your coolant or vacuum hoses. Avoid the risk of leaks by replacing old clamps with new hardware, offering peace of mind against coolant and vacuum system issues.

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.
  • Adjustable size from 70mm to 78mm for versatile applications.

Upgrade your hose clamps to ensure optimal performance and reliability in your BMW's systems.

The perfect upgrade for your connection between your thermostat and cylinder head. Designed using durable silicone and billet aluminum to greatly outlast the OE rubber and plastic combination.

Some of the weakest point of the cooling systems in BMW's can come down to the OE plastic fittings breaking down from the constant changes in temperature softening these plastic components. When this happens even simply moving the hose slightly could cause the fitting to crack causing the coolant to leak all over. The ECS design silicone hose with billet aluminum adapter retains OE fitment with superior strength to not only handle the performance, but stand up to the wear and tear of a daily driver.

Features: 

  • Manufactured from billet 6061-T6 with type III anodize for exceptional durability and corrosion resistance.

    • Much stronger part than OEM plastic

    • Will not become brittle and fatigue over time due thermal cycling.  This will prevent the part from breaking during removal and re-installation.

  • Constructed of 4-Ply reinforced silicone for improved durability over the failure prone OE rubber hose.
  • Flourosilicone lined internal layer for exceptional chemical resistance.
  • Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability.
  • Follows OEM form for perfect fitment.
  • Utilizes OEM O-ring 11537545278 to ensure a proper seal.
