BMW Cooling System Parts & Accessories for BMW 3 Series F31 (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

BMW's cooling system has long been a known weak spot, with the water pump and thermostat being two of the most common trouble areas. This remains true even in the latest B-Series engines found in 2016 and newer BMW models. This kit includes a brand-new OEM Pierburg water pump, a Bremmen thermostat (now referred to as a Heat Management Module), and one gallon of BMW's G48 coolant concentrate (enough to make two gallons of 50/50 coolant). Avoid spending thousands at the dealership or over $600 on Genuine BMW parts! These components can be replaced with high-quality OEM parts in just an afternoon using basic hand tools.

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

It is important that your coolant system is serviced at regular intervals to ensure a long life. Over time, coolant systems are exposed to high temperatures and repeated thermal cycling, which causes warping, cracking, and hardening of plastics and rubber components in the coolant system. This can lead to coolant leaks and overheating, which can result in extensive engine damage if not resolved in a timely manner. This Water Pump & Thermostat kit helps to address a few of the most problematic parts, replacing these items entirely to keep your cooling system running optimally and efficiently.

The water pump in your vehicle keeps all that coolant flowing freely. If it begins to fail, overheating problems are inevitable. Don't take a chance on doing damage to engine internals by not replacing your water pump. This has been a common problem amongst most German vehicles. Water Pump failure can lead to your vehicle making an unnecessary trip to the repair shop. If your pump stops working, coolant temperatures rise rapidly and can overheat the engine, leading to head gasket or even piston ring failure. This is a great preventative maintenance item when doing any type of timing belt replacement. This is a common replacement around 80,000-100,000 miles.

A failing water pump can show early warning signs like coolant leaks or a whining noise from the engine bay—but with electric water pumps, failure can be sudden, often with no warning beyond rapid overheating.

If you suspect your water pump is on its way out, prompt replacement is critical to avoid engine damage. Stay alert to any changes in cooling system performance.

Note: Aluminum mounting bolts are single-use and must be replaced during installation.

The coolant expansion tank in your vehicle gives additional fluid a place to go after expansion and contraction from temperature change. Because it is subjected to such drastic changes regularly, the plastic will become brittle and will often crack or break. You want to keep all the coolant in your vehicle in the cooling system to prevent overheating issues. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it.
