BMW Cooling System Parts & Accessories for BMW F87 M2 N55 3.0L

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:

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

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.
