BMW Cooling System Parts & Accessories for BMW X Series F16 (2015+)

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.

Water Pump And Thermostat Kit - BMW N55 F Chassis

Ensure optimal engine cooling and performance with this high-quality Water Pump And Thermostat Kit - BMW N55 F Chassis. In the mid-2000s, BMW introduced electronically controlled water pumps and thermostats for better temperature regulation and efficiency. However, these components tend to have a shorter lifespan compared to traditional mechanical designs, often failing before BMW’s recommended 80,000-mile service interval.

This complete kit from Turner Motorsport includes premium-quality components that match OEM specifications, providing reliable and efficient cooling system performance. Maintaining a properly functioning cooling system helps prevent overheating, enhances efficiency, and extends engine life.

Signs Your Water Pump and Thermostat May Need Replacement:

  • Engine overheating or failing to reach operating temperature
  • Water pump running intermittently or erratically
  • Cooling fans operating at maximum output
  • Engine fault codes, including 20A804

Upgrade your BMW N55 F Chassis cooling system with this all-in-one kit for worry-free performance and longevity.

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.
