BMW Cooling System Parts & Accessories for BMW 5 Series G30 (2017+)

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 cooling system has always been a weak point for BMW. Two of the biggest issues are the water pump and thermostat. This continues to be true even on the newest B-Series engines found in 2016+ BMWs. This kit includes a brand new Genuine BMW water pump, a new thermostat (now referred to as a Heat Management Module), and 1 gallon of BMW's G48 coolant concentrate (makes 2 gallons of 50/50 coolant). Don't spend thousands of dollars at the dealership, these can easily be replaced in an afternoon with basic mechanic's tools.

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: Genuine BMW Mechanical Pump Genuine BMW 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.

Engine oil coolers help reduce the oil temperature, preventing the oil from breaking down prematurely and losing its lubricating properties. Engine oil coolers play a crucial role in regulating oil temperature, ensuring proper lubrication, and optimizing engine performance and longevity. Engine oil that is too hot drops in viscosity and does not provide adequate lubrication to sensitive engine components such as bearings, which can fail catastrophically if not properly lubricated. If your engine oil cooler has been damaged or has failed we recommend replacing it to ensure no damage occurs to your engine.

Auxillary water pumps are electric water pumps that pump coolant to critical components of your BMW. A failing pump can cause excessive noise and intermittent cooling issues, leading to potential damage if not replaced quickly enough. If the electric motor dies completely, chances are any parts downstream from the pump will overheat and fail, leading to costly repairs and replacements. Prevent this from happening by installing this brand new Auxillary Water Pump from OEM Bosch!
