BMW Cooling System Parts & Accessories for BMW 4 Series F32 (2014+)

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 N20/n26 engined cars already suffer from reduced cooling area because of the factory intercooler, tight space under the hood, and of course heat from the turbo(s). BMW addressed these challenges a number of ways, including a dynamic, 'smart' electric water pump with increased output compared to normally aspirated models. The cooling demands mean additional stress on the major cooling components, especially the water pump and thermostat. 
 

Kit includes:

  • Mahle-Behr thermostat
  • Pierburg water pump
  • Genuine BMW coolant
  • Mounting hardware required for both the thermostat and water pump

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.

Kit includes

  • Wahler Thermostat
  • 1 liter of Coolant

If your water pump is leaking coolant, there is a good chance one of the seals has failed. This is especially common when your coolant level gets too low and your BMW's water pump runs without coolant. The water pump shaft seal can fail as it gets too hot and you will begin to notice coolant dripping from the weep hole found at the bottom of your pump. We recommend replacing the whole pump to ensure your BMW stays cool for many more years! This kit includes the basic parts necessary to replace your water pump: GEBA Mechanical Pump with an upgraded metal impeller Elring Water Pump Gasket Genuine BMW Water Pump Bolts (x6) Don't forget to pick up a gallon of BMW coolant as well to top your system back off once you have completed your pump installation! Servicing your accessory belt and tensioner is also great to do at this time as the belt must be removed before replacing your pump.

Genuine BMW expansion tanks have a bad habit of failing after a few years. This has primarily been caused by the plastic construction of the expansion tanks. After enough heat cycles, the plastic becomes brittle and can crack, causing coolant to leak out and air to enter the coolant system. If a failing expansion tank is not addressed soon enough, the coolant loss can lead to an overheating engine. This kit includes two brand new high quality expansion tanks and caps

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.
